24.05.2 / 2024-06-13 Release

📌 This release is identical to 24.05.0, with the addition of two fixes:

1. A fix that makes the NFS Troubleshooting dashboards load in NAbox and via bin/harvest grafana import.
2. A fix for a regression introduced in 24.05.1, that causes FlexGroup volume performance metrics to be skipped.

Upgrade Recommendation: You should upgrade to 24.05.2 if any of the following apply to you:

• You want to use the NFS troubleshooting dashboards.
• You are on version 24.05.1 and your cluster includes FlexGroup volumes.

---

24.05.1 / 2024-05-29 Release

📌 This release is the same as 24.05.0 with a fix that makes the NFS Troubleshooting dashboards load in NAbox. If you are not using NAbox or you do not use the NFS trouble shooting dashboards, you can ignore this release.

---

Announcements

‼️ IMPORTANT Release 24.05 removes duplicate quota metrics. If you wish to enable them, refer here.

💡 IMPORTANT After upgrading, don't forget to re-import your dashboards to get all the new enhancements and fixes. You can import them via the 'bin/harvest grafana import' CLI, from the Grafana UI, or from the 'Maintenance > Reset Harvest Dashboards' button in NAbox.

Known Issues

• ⚠️ Harvest does not calculate power metrics for AFF A250 systems. This data is not available from ONTAP via ZAPI or REST. See ONTAP bug 1511476 for more details.
• ⚠️ ONTAP does not include REST metrics for offbox_vscan_server and offbox_vscan until ONTAP 9.13.1. See ONTAP bug 1473892 for more details.

IMPORTANT 7-mode filers that are not on the latest release of ONTAP may experience TLS connection issues with errors like tls: server selected unsupported protocol version 301. This is caused by a change in Go 1.18. The default for TLS client connections was changed to TLS 1.2 in Go 1.18. Please upgrade your 7-mode filers (recommended) or set tls_min_version: tls10 in your harvest.yml poller section. See #1007 for more details.

Announcements

‼️ IMPORTANT Release 24.02 disables four templates that collected metrics not used in dashboards. These four templates are disabled by default: ObjectStoreClient, TokenManager, OntapS3SVM, and Vscan. This change was made to reduce the number of collected metrics. If you require these templates, you can enable them by uncommenting them in their corresponding default.yaml or by extending the existing object template.

🔺 IMPORTANT The minimum version of Prometheus required to run Harvest is now 2.33. Version 2.33 is required to take advantage of Prometheus's @ modifier. Please upgrade your Prometheus server to at least 2.33 before upgrading Harvest.

💡 IMPORTANT After upgrade, don't forget to re-import your dashboards, so you get all the new enhancements and fixes. You can import them via the 'bin/harvest grafana import' CLI, from the Grafana UI, or from the 'Maintenance > Reset Harvest Dashboards' button in NAbox.

Known Issues

• Harvest does not calculate power metrics for AFF A250 systems. This data is not available from ONTAP via ZAPI or REST. See ONTAP bug 1511476 for more details.

• ONTAP does not include REST metrics for offbox_vscan_server and offbox_vscan until ONTAP 9.13.1. See ONTAP bug 1473892 for more details.

IMPORTANT 7-mode filers that are not on the latest release of ONTAP may experience TLS connection issues with errors like tls: server selected unsupported protocol version 301 This is caused by a change in Go 1.18. The default for TLS client connections was changed to TLS 1.2 in Go 1.18. Please upgrade your 7-mode filers (recommended) or set tls_min_version: tls10 in your harvest.yml poller section. See #1007 for more details.

Announcements

‼️ IMPORTANT Due to ONTAP bug 1585893 the Harvest team recommends using ZapiPerf instead of RestPerf when collecting performance metrics. The RestPerf collector can be used once you upgrade your cluster to a version of ONTAP with the fix. Details in 1585893.

‼️ IMPORTANT Release 23.11 disables the CIFSSession templates by default. This change was made to prevent the generation of a large number of metrics. If you require these templates, you can enable them. Please be aware that enabling them may result in a significant increase in metric collection time, Harvest memory footprint, and Prometheus used disk space. These metrics are utilized in the SMB2 dashboard.

‼️ IMPORTANT Release 23.11 has updated its power metric calculation algorithm. As a result, you may notice a decrease in the reported power metrics compared to previous versions. To collect these metrics, Rest API permissions are required. For detailed information on the power algorithm, please refer to the power algorithm documentation.

‼️ IMPORTANT NetApp moved their communities from Slack to Discord, please join us there!

💡 IMPORTANT After upgrade, don't forget to re-import your dashboards, so you get all the new enhancements and fixes. You can import them via the bin/harvest grafana import CLI, from the Grafana UI, or from the Maintenance > Reset Harvest Dashboards button in NAbox.

Known Issues

• Some AFF A250 systems do not report power metrics. See ONTAP bug 1511476 for more details.

• ONTAP does not include REST metrics for offbox_vscan_server and offbox_vscan until ONTAP 9.13.1. See ONTAP bug 1473892 for more details.

IMPORTANT 7-mode filers that are not on the latest release of ONTAP may experience TLS connection issues with errors like tls: server selected unsupported protocol version 301 This is caused by a change in Go 1.18. The default for TLS client connections was changed to TLS 1.2 in Go 1.18. Please upgrade your 7-mode filers (recommended) or set tls_min_version: tls10 in your harvest.yml poller section. See #1007 for more details.

23.08.0 / 2023-08-21 Release

📌 Highlights of this major release include:

• Harvest Security dashboard highlights compliance using NetApp's Security hardening guide for ONTAP

• Harvest's credential script supports ONTAP daily credential rotation. Thanks to @mamoep for raising.

• 🎩 Harvest makes it easy to run with both the ZAPI and REST collectors at the same time. Overlapping resources are deduplicated and only exported once. Harvest will automatically upgrade ZAPI conversations to REST when ZAPIs are suspended or disabled.

• 💎 Updated workload dashboard now includes Service Center, Latency Breakdown, and 50 panels

• 💎 Cluster dashboard updated to work with FSx. Some panels are blank because FSx does not have that data.

• 📣 The Harvest team published a couple of screencasts about:

  • Why Harvest
  • Harvest Quick Start: Docker Compose

• ⭐ Several of the existing dashboards include new panels in this release:

  • Aggregate dashboard includes busy volume panels
  • SVM dashboard includes per NFS latency heatmaps. Thanks to @rbrownATnetapp for raising.
  • Volume dashboard includes top resources by other IOPs panel and junction paths. Thanks to @tsohst for raising.

• All Harvest dashboard tables include column filters

• Harvest dashboards use color to highlight latency and busy threshold breaches

• Harvest's Prometheus exporter supports TLS

• 🌾 Harvest includes new templates to collect:

  • Iwarp metrics
  • FCVI metrics
  • Per volume NFS metrics
  • Volume clone metrics
  • QoS workload policy metrics
  • NVME/TCP and NVME/RoCE metrics
  • Flashpool metrics are included in RestPerf. Thanks to @lobster1860 for raising

• 📕 Documentation additions

  • Move more documentation from GitHub to Harvest documentation site
  • Clarify how to tell Harvest to continue using the ZAPI protocol
  • Clarify generic vs custom plugins. Thanks to GregS for raising
  • Clarify which version of Go is required to build Harvest. Thanks to MikeK for raising
  • Clarify how to prepare ONTAP cDOT clusters for Harvest data collection
  • EMS documentation should point to Harvest documentation site. Thanks to @cwaltham for raising
  • Clarify how to gather log files on all platforms
  • Explain how to use the --labels option of bin/harvest grafana. Thanks to @slater0013 for raising
  • Describe how to run docker compose generate command without required Harvest binaries

• The Harvest doctor command validates collector names listed in your harvest.yml file

• An earlier version of Harvest collected cloud store information via REST. This release adds the same for ZAPI

• When ONTAP resources are missing, Harvest tries to collect them every hour. Earlier versions of Harvest waited 24 hours before retrying, which often caused metrics to be missing after a cluster upgrade. Thanks to @Falcon667 for raising

• Earlier versions of Harvest created world writable auto-support files. These files are now only read/writeable by the current user. Thanks to Bunnygirl for raising

• bin/harvest import should work with Grafana 10. Thanks to @wooyoungAhn for raising

Announcements

‼️ IMPORTANT 23.08 fixes a REST collector bug that caused partial data collection when ONTAP paginated results. See #2109 for details.

‼️ IMPORTANT Release 23.08 disables the NetConnections and NFSClients templates by default. You can enable them if needed. These templates were disabled because several customers reported that these templates created millions of metrics. None of these metrics are used in Harvest dashboards.

‼️ IMPORTANT Release 23.08 changes how Harvest monitors workloads. For detailed information, please refer to the discussion #2265.

💡 The Compliance dashboard was removed after its panels were moved to the Security dashboard.

👀 Ambient temperature metric may experience an increase due to issue #2259

‼️ IMPORTANT NetApp moved their communities from Slack to Discord, please join us there!

‼️ IMPORTANT If using Docker Compose and you want to keep your historical Prometheus data, please read how to migrate your Prometheus volume

💡 IMPORTANT After upgrade, don't forget to re-import your dashboards, so you get all the new enhancements and fixes. You can import them via the bin/harvest grafana import CLI, from the Grafana UI, or from the Maintenance > Reset Harvest Dashboards button in NAbox.

Known Issues

• Some AFF A250 systems do not report power metrics. See ONTAP bug 1511476 for more details.

• ONTAP does not include REST metrics for offbox_vscan_server and offbox_vscan until ONTAP 9.13.1. See ONTAP bug 1473892 for more details.

IMPORTANT 7-mode filers that are not on the latest release of ONTAP may experience TLS connection issues with errors like tls: server selected unsupported protocol version 301 This is caused by a change in Go 1.18. The default for TLS client connections was changed to TLS 1.2 in Go 1.18. Please upgrade your 7-mode filers (recommended) or set tls_min_version: tls10 in your harvest.yml poller section. See #1007 for more details.

23.05.0 / 2023-05-03

📌 Highlights of this major release include:

• 💎 Seven new dashboards:

  • StorageGRID and ONTAP fabric pool
  • Health
  • S3 object storage
  • External service operations
  • Namespace
  • SMB
  • Workloads

• ⭐ Several of the existing dashboards include new panels in this release:

  • Qtree dashboard includes topK qtrees by disk-used growth
  • StorageGRID Overview dashboard includes traffic classification panels
  • Network dashboard includes net routes
  • Average CPU utilization and CPU busy are included in the cDOT, Cluster, Node, and Metrocluster dashboards
  • SVM dashboard includes LIF counters and the NFS panels filter graphs by NFS version
  • Volume dashboard includes efficiency statistics
  • Aggregate dashboard includes the amount of free space
  • Compliance dashboard only reports on data SVMs

• 🔐 Harvest can fetch cluster credentials via a credential script. Thanks to Ed Wilts for raising.

• 🌾 Harvest includes new templates to collect:

  • IP routes. Thanks jfong for contributing!
  • QoS fixed and adaptive policy groups. Thanks @faguayot for raising!
  • Cloud targets and storage
  • Export rules
  • Namespaces
  • CIFS clients
  • LIF counters
  • Volume efficiency stats

• Harvest containers are published to GitHub's container registry in addition to DockerHub and cr.netapp.io. If you're using cr.netapp.io, we encourage you to switch to ghcr.io or DockerHub. In 2024, we will stop publishing to cr.netapp.io

• Harvest uses a distroless image as its base now - reducing the size of the container and reducing the attack surface

• Harvest collects 38 additional EMS events and alert rules in this release

• Harvest EMS alert rules were updated to include better label names and align their severity with Prometheus best practices. Thanks to @7840vz for contributing this feature!

• The bin/harvest doctor tool validates your custom.yaml template files, checking them for errors.

• 📕 Documentation additions

  • How to set up Harvest with Kubernetes
  • Harvest metadata metrics
  • Authenticating with ONTAP and StorageGRID clusters and auth precedence
  • Pollers include a prefer_zapi flag that tells Harvest to use the ZAPI API if the cluster supports it, otherwise allow Harvest to choose REST or ZAPI, whichever is appropriate to the ONTAP version. See rest-strategy for details.

• 🎩 Harvest makes it easy to run with both the ZAPI and REST collectors at the same time. Overlapping resources are deduplicated and only published to Prometheus once. This was the final piece in our journey to REST. See rest-strategy.md if you are interested in the details.

Announcements

IMPORTANT The volume_aggr_labels metric is being deprecated in the 23.05 release and will be removed in the 23.08 release of Harvest (#1966) volume_aggr_labels is redundant and the same labels are already available via volume_labels.

IMPORTANT To reduce image and download size, several tools were combined in 23.05. The following binaries are no longer included: bin/grafana, bin/rest, bin/zapi. Use bin/harvest grafana, bin/harvest rest, and bin/harvest zapi instead.

‼️ IMPORTANT NetApp moved their communities from Slack to Discord, please join us there!

‼️ IMPORTANT If using Docker Compose and you want to keep your historical Prometheus data, please read how to migrate your Prometheus volume

💡 IMPORTANT After upgrade, don't forget to re-import your dashboards, so you get all the new enhancements and fixes. You can import them via the bin/harvest grafana import CLI, from the Grafana UI, or from the Maintenance > Reset Harvest Dashboards button in NAbox.

Known Issues

• Harvest does not calculate power metrics for AFF A250 systems. This data is not available from ONTAP via ZAPI or REST. See ONTAP bug 1511476 for more details.

• ONTAP does not include REST metrics for offbox_vscan_server and offbox_vscan until ONTAP 9.13.1. See ONTAP bug 1473892 for more details.

IMPORTANT 7-mode filers that are not on the latest release of ONTAP may experience TLS connection issues with errors like tls: server selected unsupported protocol version 301 This is caused by a change in Go 1.18. The default for TLS client connections was changed to TLS 1.2 in Go 1.18. Please upgrade your 7-mode filers (recommended) or set tls_min_version: tls10 in your harvest.yml poller section. See #1007 for more details.

23.02.0 / 2023-02-21

📌 Highlights of this major release include:

• ✨ Harvest includes a new file system analytics (FSA) dashboard with directory growth, top directories per volume, and volume usage statistics.

• Harvest includes a new StorageGRID overview dashboard with performance, storage, information lifecycle management, and node panels. We're collecting suggestions on which StorageGRID dashboards you'd like to see next in issue #1420.

• 💡 Power dashboard includes new panels for total power by aggregate disk type, average power per used TB, average IOPs/Watt, total power by aggregate, and information on sensor problems.

• 🎩 Harvest makes it easy to run with both the ZAPI and REST collectors at the same time. Overlapping resources are deduplicated and only published to Prometheus once. This was the final piece in our journey to REST. See rest-strategy.md if you are interested in the details.

• 📕 We made lots of improvements to Harvest's new documentation site this release including one of the most requested features - a list of Harvest metrics and their corresponding ONTAP ZAPI/REST API mappings. 📐 Check it out

• 💎 New dashboards and improvements

  • A new file system analytics (FSA) dashboard with directory growth, top directories per volume, and volume usage statistics
  • A new StorageGRID overview dashboard with performance, storage, information lifecycle management, and node panels
  • Power dashboard includes new panels for total power by aggregate disk type, average power per used TB, average IOPs/Watt, total power by aggregate, and information on sensor problems.
  • Disk dashboard shows which node/controller a disk belongs too
  • SVM dashboard shows topK resources in panel drill downs
  • SnapMirror dashboard includes transfer duration, lag time and transfer data panels in addition to new source and destination volume variables to make it easier to understand SnapMirror relationships
  • Aggregate dashboard includes a new flash pool drill down with five new panels
  • Aggregate dashboard includes four new panels showing volume statistics broken down by flexvol/flexgroup space per aggregate
  • SVM dashboard includes NFSv3 latency heatmap panels
  • Node dashboard latency panels updated to use weighted average, bringing them inline with ActiveIQ
  • Volume dashboard includes new inode usage panels

• Harvest includes a new command bin/harvest grafana metrics which shows which metrics each dashboard uses

Announcements

‼️ IMPORTANT NetApp moved their communities from Slack to Discord, please join us there!

‼️ IMPORTANT If using Docker Compose and you want to keep your historical Prometheus data, please read how to migrate your Prometheus volume

💡 IMPORTANT After upgrade, don't forget to re-import your dashboards, so you get all the new enhancements and fixes. You can import them via the bin/harvest/grafana import CLI, from the Grafana UI, or from the Maintenance > Reset Harvest Dashboards button in NAbox.

🌻 In the 22.11.0 release notes, we announced that we would be removing quota metrics prefixed with qtree. Several of you asked us to leave them. 👍 We will continue publishing them as-is.

Known Issues

• Harvest does not calculate power metrics for AFF A250 systems. This data is not available from ONTAP via ZAPI or REST. See ONTAP bug 1511476 for more details.

• ONTAP does not include REST metrics for offbox_vscan_server and offbox_vscan until ONTAP 9.13.1. See ONTAP bug 1473892 for more details.

IMPORTANT 7-mode filers that are not on the latest release of ONTAP may experience TLS connection issues with errors like tls: server selected unsupported protocol version 301 This is caused by a change in Go 1.18. The default for TLS client connections was changed to TLS 1.2 in Go 1.18. Please upgrade your 7-mode filers (recommended) or set tls_min_version: tls10 in your harvest.yml poller section. See #1007 for more details.

22.11.0 / 2022-11-21

📌 Highlights of this major release include:

• ✨ Harvest now includes a StorageGRID collector and a Tenant/Buckets dashboard. We're just getting started with StorageGRID dashboards. Please give the collector a try, and let us know which StorageGRID dashboards you'd like to see next.

• 🎩 The REST collectors are ready! We recommend using them for ONTAP versions 9.12.1 and higher. Today, Harvest collects 1,546 metrics via ZAPI. Harvest includes a full set of REST templates that export identical metrics. All 1,546 metrics are available via Harvest's REST templates and no changes to dashboards or downstream metric-consumers is required. 🎉 More details on Harvest's REST strategy.

• 📕 Harvest has a new documentation site! This consolidates Harvest documentation into one place and will make it easier to find what you need. Stay tuned for more updates here.

• 💎 New and improved dashboards

  • cDOT, high-level cluster overview dashboard
  • Headroom dashboard
  • Quota dashboard
  • Snapmirror dashboard shows source and destination side of relationship
  • NFS clients dashboard
  • Fabric Pool panels are now included in Volume dashboard
  • Tags are included for all default dashboards, making it easier to find what you need
  • Additional throughput, ops, and utilization panels were added to the Aggregate, Disk, and Clusters dashboards
  • Harvest dashboards updated to enable multi-select variables, shared crosshairs, better top n resources support, and all variables are sorted by default.

• 🔒 Harvest code is checked for vulnerabilities on every commit using Go's vulnerability management scanner.

• Harvest collects additional metrics in this release

  • ONTAP S3 server config metrics
  • User defined volume workload
  • Active network connections
  • NFS connected clients
  • Network ports
  • Netstat packet loss

• Harvest now converts ONTAP histograms to Prometheus histograms, making it possible to visualize metrics as heatmaps in Grafana

Announcements

‼️ IMPORTANT NetApp moved their communities from Slack to Discord, please join us there!

💣 Deprecation: Earlier versions of Harvest published quota metrics prefixed with qtree. Harvest release 22.11 deprecates the quota metrics prefixed with qtree and instead publishes quota metrics prefixed with quota. All dashboards have been updated. If you are consuming these metrics outside the default dashboards, please change to quota prefixed metrics. Harvest release 23.02 will remove the deprecated quota metrics prefixed with qtree.

‼️ IMPORTANT If using Docker Compose and you want to keep your historical Prometheus data, please read how to migrate your Prometheus volume

💡 IMPORTANT After upgrade, don't forget to re-import your dashboards, so you get all the new enhancements and fixes. You can import them via the bin/harvest/grafana import CLI, from the Grafana UI, or from the Maintenance > Reset Harvest Dashboards button in NAbox.

Known Issues

• Harvest does not calculate power metrics for AFF A250 systems. This data is not available from ONTAP via ZAPI or REST. See ONTAP bug 1511476 for more details.

• ONTAP does not include REST metrics for offbox_vscan_server and offbox_vscan until ONTAP 9.13.1. See ONTAP bug 1473892 for more details.

• Podman is unable to pull from NetApp's container registry cr.netapp.io. Until issue is resolved, Podman users can pull from a separate proxy like this podman pull netappdownloads.jfrog.io/oss-docker-harvest-production/harvest:latest.

IMPORTANT 7-mode filers that are not on the latest release of ONTAP may experience TLS connection issues with errors like tls: server selected unsupported protocol version 301 This is caused by a change in Go 1.18. The default for TLS client connections was changed to TLS 1.2 in Go 1.18. Please upgrade your 7-mode filers (recommended) or set tls_min_version: tls10 in your harvest.yml poller section. See #1007 for more details.

The Unix collector is unable to monitor pollers running in containers. See #249 for details.

22.08.0 / 2022-08-19

🚀 Highlights of this major release include:

• 🎇 an ONTAP event management system (EMS) events collector with 64 events out-of-the-box

• Two new dashboards added in this release

  • Headroom dashboard
  • Quota dashboard

• We've made lots of improvements to the REST Perf collector. The REST Perf collector should be considered early-access as we continue to improve it. This feature requires ONTAP versions 9.11.1 and higher.

• New max plugin that creates new metrics from the maximum of existing metrics by label.

• New compute_metric plugin that creates new metrics by combining existing metrics with mathematical operations.

• 48 feature, 45 bug fixes, and 11 documentation commits this release

IMPORTANT ‼️ NetApp is moving their communities from Slack to NetApp's Discord with a plan to lock the Slack channel at the end of August. Please join us on Discord!

IMPORTANT ‼️ Prometheus version 2.26 or higher is required for the EMS Collector.

IMPORTANT ‼️ After upgrade, don't forget to re-import your dashboards, so you get all the new enhancements and fixes. You can import them via the bin/harvest/grafana import CLI or from the Grafana UI.

Known Issues

Podman is unable to pull from NetApp's container registry cr.netapp.io. Until issue is resolved, Podman users can pull from a separate proxy like this podman pull netappdownloads.jfrog.io/oss-docker-harvest-production/harvest:latest.

IMPORTANT 7-mode filers that are not on the latest release of ONTAP may experience TLS connection issues with errors like tls: server selected unsupported protocol version 301 This is caused by a change in Go 1.18. The default for TLS client connections was changed to TLS 1.2 in Go 1.18. Please upgrade your 7-mode filers (recommended) or set tls_min_version: tls10 in your harvest.yml poller section. See #1007 for more details.

The Unix collector is unable to monitor pollers running in containers. See #249 for details.

22.05.0 / 2022-05-11

🚀 Highlights of this major release include:

• Early access to ONTAP REST perf collector from ONTAP 9.11.1GA+

• ⌛ New Container Registry - Several of you have mentioned that you are being rate-limited when pulling Harvest Docker images from DockerHub. To alleviate this problem, we're publishing Harvest images to NetApp's container registry (cr.netapp.io). Going forward, we'll publish images to both DockerHub and cr.netapp.io. More information in the FAQ. No action is required unless you want to switch from DockerHub to cr.netapp.io. If so, the FAQ has you covered.

• Five new dashboards added in this release

  • Power dashboard
  • Compliance dashboard
  • Security dashboard
  • Qtree dashboard
  • NFSv4 Store Pool dashboard (disabled by default)

• New value_to_num_regex plugin allows you to map all matching expressions to 1 and non-matching ones to 0.

• Harvest pollers can optionally read credentials from a mounted volume or file. This enables Hashicorp Vault support and works especially well with Vault agent

• bin/grafana import provides a --multi flag that rewrites dashboards to include multi-select dropdowns for each variable at the top of the dashboard

• The conf/rest collector templates received a lot of attentions this release. All known gaps between the ZAPI and REST collector have been filled and there is full parity between the two from ONTAP 9.11+. 🤘

• 24 bug fixes, 47 feature, and 5 documentation commits this release

IMPORTANT ‼️ After upgrade, don't forget to re-import your dashboards so you get all the new enhancements and fixes. You can import via bin/harvest/grafana import cli or from the Grafana UI.

IMPORTANT The conf/zapiperf/cdot/9.8.0/object_store_client_op.yaml ZapiPerf template is being deprecated in this release and will be removed in the next release of Harvest. No dashboards use the counters defined in this template and all counters are being deprecated by ONTAP. If you are using these counters, please create your own copy of the template.

Known Issues

IMPORTANT 7-mode filers that are not on the latest release of ONTAP may experience TLS connection issues with errors like tls: server selected unsupported protocol version 301 This is caused by a change in Go 1.18. The default for TLS client connections was changed to TLS 1.2 in Go 1.18. Please upgrade your 7-mode filers (recommended) or set tls_min_version: tls10 in your harvest.yml poller section. See #1007 for more details.

The Unix collector is unable to monitor pollers running in containers. See #249 for details.

22.02.0 / 2022-02-15

💥 Highlights of this major release include:

• Continued progress on the ONTAP REST config collector. Most of the template changes are in place and we're working on closing the gaps between ZAPI and REST. We've made lots of improvements to the REST collector and included 13 REST templates in this release. The REST collector should be considered early-access as we continue to improve it. If you try it out or have any feedback, let us know on Slack or GitHub. 📖 You can find more information about when you should switch from ZAPI to REST, what versions of ONTAP are supported by Harvest's REST collector, and how to fill ONTAP gaps between REST and ZAPI documented here

• Many of you asked for nightly builds. We have them. 🎊 We're also working on publishing to multiple Docker registries since you've told us you're running into rate-limiting problems with DockerHub. We'll announce here and Slack when we have a solution in place.

• Two new Data Protection dashboards

• bin/grafana cli should not overwrite dashboard changes, making it simpler to import/export dashboards, and enabling round-tripping dashboards (import, export, re-import)

• New include_contains plugin allows you to select a subset of objects. e.g. selecting only volumes with custom-defined ONTAP metadata

• We've included more out-of-the-box Prometheus alerts. Keep sharing your most useful alerts!

• 7mode workflows continue to be improved ❤️ Harvest now collects Qtree and Quotas counters from 7mode filers (these are already collected in cDOT)

• 28 bug fixes, 52 feature, and 11 documentation commits this release

IMPORTANT Admin node certificate file location changed. Certificate files have been consolidated into the cert directory. If you created self-signed admin certs, you need to move the admin-cert.pem and admin-key.pem files into the cert directory.

IMPORTANT In earlier versions of Harvest, the Qtree template exported the vserver metric. This counter was changed to svm to be consistent with other templates. If you are using the qtree vserver metric, you will need to update your queries to use svm instead.

IMPORTANT ‼️ After upgrade, don't forget to re-import your dashboards so you get all the new enhancements and fixes. You can import via bin/harvest/grafana import cli or from the Grafana UI.

IMPORTANT The LabelAgent value_mapping plugin was deprecated in the 21.11 release and removed in 22.02. Use LabelAgent value_to_num instead. See docs for details.

Known Issues

The Unix collector is unable to monitor pollers running in containers. See #249 for details.

21.11.1 / 2021-12-10

This release is the same as 21.11.0 with an FSx dashboard fix for #737. If you are not monitoring an FSx system the 21.11.0 release is the same, no need to upgrade. We reverted a node-labels check in those dashboards because Harvest does not collect node data from FSx systems.

21.11.0 / 2021-11-08

Highlights of this major release include:

• Early access to ONTAP REST collector
• Support for Prometheus HTTP service discovery
• New MetroCluster dashboard
• Qtree and Quotas collection
• We heard your ask, and we made it happen. We've separated cDOT and 7mode dashboards so each can evolve independently
• Label sets allow you to add additional key-value pairs to a poller's metrics#538 and expose those labels in your dashboards
• Template merging was improved to keep your template changes separate from Harvest's
• Harvest poller's are more deterministic about picking free ports
• 37 bug fixes

IMPORTANT The LabelAgent value_mapping plugin is being deprecated in this release and will be removed in the next release of Harvest. Use LabelAgent value_to_num instead. See docs for details.

IMPORTANT After upgrade, don't forget to re-import all dashboards so you get new dashboard enhancements and fixes. You can re-import via bin/harvest/grafana cli or from the Grafana UI.

IMPORTANT RPM and Debian packages will be deprecated in the future, replaced with Docker and native binaries. See #330 for details and tell us what you think. Several of you have already weighed-in. Thanks! If you haven't, please do.

Known Issues

The Unix collector is unable to monitor pollers running in containers. See #249 for details.

Enhancements

• 🚧 ONTAP started moving their APIs from ZAPI to REST in ONTAP 9.6. Harvest adds an early access ONTAP REST collector in this release (config only). 🎊 This is our first step among several as we prepare for the day that ZAPIs are turned off. The REST collector and seven templates are included in 21.11. These should be considered early access as we continue to improve them. If you try them out or have any feedback, let us know on Slack or GitHub. #402

21.08.0 / 2021-08-31

This major release introduces a Docker workflow that makes it a breeze to standup Grafana, Prometheus, and Harvest with auto-provisioned dashboards. There are seven new dashboards, example Prometheus alerts, and a bunch of fixes detailed below. We haven't forgotten about our 7-mode customers either and have a number of improvements in 7-mode dashboards with more to come.

This release Harvest also sports the most external contributions to date. :metal: Thanks!

With 284 commits since 21.05, there is a lot to summarize! Make sure you check out the full list of enhancements and improvements in the CHANGELOG.md since 21.05.

IMPORTANT Harvest relies on the autosupport sidecar binary to periodically send usage and support telemetry data to NetApp by default. Usage of the harvest-autosupport binary falls under the NetApp EULA. Automatic sending of this data can be disabled with the autosupport_disabled option. See Autosupport for details.

IMPORTANT RPM and Debian packages will be deprecated in the future, replaced with Docker and native binaries. See #330 for details and tell us what you think. Several of you have already weighed-in. Thanks! If you haven't, please do.

IMPORTANT After upgrade, don't forget to re-import all dashboards so you get new dashboard enhancements and fixes. You can re-import via bin/harvest/grafana cli or from the Grafana UI.

Known Issues

We've improved several of the 7-mode dashboards this release, but there are still a number of gaps with 7-mode dashboards when compared to c-mode. We will address these in a point release by splitting the c-mode and 7-mode dashboards. See #423 for details.

On RHEL and Debian, the example Unix collector does not work at the moment due to the harvest user lacking permissions to read the /proc filesystem. See #249 for details.

Enhancements

21.05.4 / 2021-07-22

This release introduces Qtree protocol collection, improved Docker and client authentication documentation, publishing to Docker Hub, and a new plugin that helps build richer dashboards, as well as a couple of important fixes for collector panics.

IMPORTANT RPM and Debian packages will be deprecated in the future, replaced with Docker and native binaries. See #330 for details and tell us what you think.

Known Issues

21.05.3 / 2021-06-28

This release introduces a significantly simplified way to connect Harvest and Prometheus, improves Harvest builds times by 7x, reduces executable sizes by 3x, enables cross compiling support, and includes several Grafana dashboard and collector fixes.

Known Issues

On RHEL and Debian, the example Unix collector does not work at the moment due to the harvest user lacking permissions to read the /proc filesystem. See #249 for details.

Enhancements

• Create Prometheus port range exporter that allows you to connect multiple pollers to Prometheus without needing to specify a port-per-poller. This makes it much easier to connect Prometheus and Harvest; especially helpful when you're monitoring many clusters #172

• Improve Harvest build times by 7x and reduce executable sizes by 3x #100

• Improve containerization with the addition of a poller-per-container Dockerfile. Create a new subcommand harvest generate docker which generates a docker-compose.yml file for all pollers defined in your config

• Improve systemd integration by using instantiated units for each poller and a harvest target to tie them together. Create a new subcommand harvest generate systemd which generates a Harvest systemd target for all pollers defined in your config #systemd

• Harvest doctor checks that all Prometheus exporters specify a unique port #118

• Harvest doctor warns when an unknown exporter type is specified (likely a spelling error) #118

• Add Harvest CUE validation and type-checking #208

• bin/zapi uses the --config command line option to read the harvest config file. This brings this tool inline with other Harvest tools. This makes it easier to switch between multiple sets of harvest.yml files.

• Harvest no longer writes pidfiles; simplifying management code and install #159

Fixes

• Ensure that the Prometheus exporter does not create duplicate labels #132

• Ensure that the Prometheus exporter includes HELP and TYPE metatags when requested. Some tools require these #104

• Disk status should return zero for a failed disk and one for a healthy disk. Thanks to @hashi825 for reporting and fixing #182

• Lun info should be collected by Harvest. Thanks to @hashi825 for reporting and fixing #230

• Grafana dashboard units, typo, and filtering fixes. Thanks to @mamoep, @matejzero, and @florianmulatz for reporting these 🎉 #184 #186 #190 #192 #195 #202

• Unix collector should not panic when harvest.yml is changed #160

• Reduce log noise about poller lagging behind by few milliseconds. Thanks @hashi825 #214

• Don't assume debug when foregrounding the poller process. Thanks to @florianmulatz for reporting. #246

• Improve Docker all-in-one-container argument handling and simplify building in air gapped environments. Thanks to @optiz0r for reporting these issues and creating fixes. #166 #167 #168

21.05.1 / 2021-05-20

Announcing the release of Harvest2. With this release the core of Harvest has been completely rewritten in Go. Harvest2 is a replacement for the older versions of Harvest 1.6 and below.

If you're using one of the Harvest 2.x release candidates, you can do a direct upgrade.

Going forward Harvest2 will follow a year.month.fix release naming convention with the first release being 21.05.0. See SUPPORT.md for details.

IMPORTANT v21.05 increased Harvest's out-of-the-box security posture - self-signed certificates are rejected by default. You have two options:

1. Setup client certificates for each cluster
2. Disable the TLS check in Harvest. To disable, you need to edit harvest.yml and add use_insecure_tls=true to each poller or add it to the Defaults section. Doing so tells Harvest to ignore invalid TLS certificates.

IMPORTANT RPM and Debian packages will be deprecated in the future, replaced with Docker and native packages.

IMPORTANT Harvest 1.6 is end of support. We recommend you upgrade to Harvest 21.05 to take advantage of the improvements.

Changes since rc2

Fixes

• Log mistyped exporter names and continue, instead of stopping
• harvest grafana should work with custom harvest.yml files passed via --config
• Harvest will try harder to stop pollers when they're stuck
• Add Grafana version check to ensure Harvest can talk to a supported version of Grafana
• Normalize rate counter calculations - improves latency values
• Workload latency calculations improved by using related objects operations
• Make cli flags consistent across programs and subcommands
• Reduce aggressive logging; if first object has fatal errors, abort to avoid repetitive errors
• Throw error when use_insecure_tls is false and there are no certificates setup for the cluster
• Harvest status fails to print port number after restart
• RPM install should create required directories
• Collector now warns if it falls behind schedule
• package.sh fails without internet connection
• Version flag is missing new line on some shells #4
• Poller should not ignore --config #28
• Handle special characters in cluster credentials #79
• TLS server verification works with basic auth #51
• Collect metrics from all disk shelves instead of one #75
• Disk serial number and is-failed are missing from cdot query #60
• Ensure collectors and pollers recover from panics #105

rc2

Fixes

• RPM package should create Harvest user and group
• Fixed many bugs (and possibly created new ones)
• Don't restart pollers without stopping them first
• Improve XML parse time by changing ZAPI collectors to request less data from ONTAP
• Fixed race condition in the Prometheus exporter (thanks to Yann Bizeul)
• Fixed non-portable function calls that would cause Harvest to crash on ARM architectures

Enhancements

• Add Debian package
• Improved metric architecture, eliminated race conditions in matrix data structure. This paves the way for other developers to create custom collectors
  • Matrix can be manipulated by collectors and plugins safely
  • Size of the matrix can be changed dynamically
  • Label data is collected (in early versions, at least one numeric metric was required)
• New plugin architecture - creating new plugins is easier and existing plugins made more generic
  • You can use built-in plugins by adding rules to a collector's template. RC2 includes two built-in plugins:
    • Aggregator: Aggregates metrics for a given label, e.g. volume data can be used to create an aggregation at the node or SVM-level
    • LabelAgent: Defines rules for rewriting instance labels, creating new labels or create ignore-lists based on regular expressions

---

rc1

IMPORTANT Harvest has been rewritten in Go

IMPORTANT Harvest no longer gathers data from AIQ Unified Manager. An install of AIQ.UM is not required.
