Project

  • [Critical] Fix a low performance issue of metrics persistent in the ElasticSearch storage implementation. One single
    metric could have to wait for an unnecessary 7~10s(System Env Variable SW_STORAGE_ES_FLUSH_INTERVAL) since 8.8.0 -
    9.1.0 releases.
  • Upgrade Armeria to 1.16.0, Kubernetes Java client to 15.0.1.

OAP Server

  • Add more entities for Zipkin to improve performance.
  • ElasticSearch: scroll id should be updated when scrolling as it may change.
  • Mesh: fix only last rule works when multiple rules are defined in metadata-service-mapping.yaml.
  • Support sending alarm messages to PagerDuty.
  • Support Zipkin kafka collector.
  • Add VIRTUAL detect type to Process for Network Profiling.
  • Add component ID(128) for Java Hutool plugin.
  • Add Zipkin query exception handler, response error message for illegal arguments.
  • Fix a NullPointerException in the endpoint analysis, which would cause missing MQ-related LocalSpan in the trace.
  • Add forEach, processRelation function to MAL expression.
  • Add expPrefix, initExp in MAL config.
  • Add component ID(7015) for Python Bottle plugin.
  • Remove legacy OAL percentile functions, p99, p95, p90, p75, p50 func(s).
  • Revert #8066. Keep all metrics persistent even it is default value.
  • Skip loading UI templates if folder is empty or doesn't exist.
  • Optimize ElasticSearch query performance by using _mGet and physical index name rather than alias in these
    scenarios, (a) Metrics aggregation (b) Zipkin query (c) Metrics query (d) Log query
  • Support the NETWORK type of eBPF Profiling task.
  • Support sumHistogram in MAL.
  • [Breaking Change] Make the eBPF Profiling task support to the service instance level,
    index/table ebpf_profiling_task is required to be re-created when bump up from previous releases.
  • Fix race condition in Banyandb storage
  • Support SUM_PER_MIN downsampling in MAL.
  • Support sumHistogramPercentile in MAL.
  • Add VIRTUAL_CACHE to Layer, to fix conjectured Redis server, which icon can't show on the topology.
  • [Breaking Change] Elasticsearch storage merge all metrics/meter and records(without super datasets) indices into one
    physical index template metrics-all and records-all on the default setting.
    Provide system environment variable(SW_STORAGE_ES_LOGIC_SHARDING) to shard metrics/meter indices into
    multi-physical indices as the previous versions(one index template per metric/meter aggregation function).
    In the current one index mode, users still could choose to adjust ElasticSearch's shard
    number(SW_STORAGE_ES_INDEX_SHARDS_NUMBER) to scale out.
    More details please refer to New ElasticSearch storage option explanation in 9.2.0
    and backend-storage doc
  • [Breaking Change] Index/table ebpf_profiling_schedule added a new column ebpf_profiling_schedule_id,
    the H2/Mysql/Tidb/Postgres storage users are required to re-created it when bump up from previous releases.
  • Fix Zipkin trace query the max size of spans.
  • Add tls and https component IDs for Network Profiling.
  • Support Elasticsearch column alias for the compatibility between storage logicSharding model and no-logicSharding model.
  • Support MySQL monitoring.
  • Support PostgreSQL monitoring.
  • Fix query services by serviceId error when Elasticsearch storage SW_STORAGE_ES_QUERY_MAX_SIZE > 10000.
  • Support sending alarm messages to Discord.
  • Fix query history process data failure.
  • Optimize TTL mechanism for Elasticsearch storage, skip executed indices in one TTL rotation.
  • Add Kubernetes support module to share codes between modules and reduce calls to Kubernetes API server.
  • Bump up Kubernetes Java client to fix cve.
  • Adapt OpenTelemetry native metrics protocol.
  • [Breaking Change] rename configuration folder from otel-oc-rules to otel-rules.
  • [Breaking Change] rename configuration field from enabledOcRules to enabledOtelRules and
    environment variable name from SW_OTEL_RECEIVER_ENABLED_OC_RULES to SW_OTEL_RECEIVER_ENABLED_OTEL_RULES.
  • [Breaking Change] Fix JDBC TTL to delete additional tables data.
    SQL Database requires removing segment,segment_tag, logs, logs_tag, alarms, alarms_tag, zipkin_span, zipkin_query before OAP starts.
  • SQL Database: add @SQLDatabase.ExtraColumn4AdditionalEntity to support add an extra column from parent to an additional table.
  • Add component ID(131) for Java Micronaut plugin
  • Add component ID(132) for Nats java client plugin

UI

  • Fix query conditions for the browser logs.
  • Implement a url parameter to activate tab index.
  • Fix clear interval fail when switch autoRefresh to off.
  • Optimize log tables.
  • Fix log detail pop-up page doesn't work.
  • Optimize table widget to hide the whole metric column when no metric is set.
  • Implement the Event widget. Remove event menu.
  • Fix span detail text overlap.
  • Add Python Bottle Plugin Logo.
  • Implement an association between widgets(line, bar, area graphs) with time.
  • Fix tag dropdown style.
  • Hide the copy button when db.statement is empty.
  • Fix legend metrics for topology.
  • Dashboard: Add metrics association.
  • Dashboard: Fix FaaS-Root document link and topology service relation dashboard link.
  • Dashboard: Fix Mesh-Instance metric Throughput.
  • Dashboard: Fix Mesh-Service-Relation metric Throughput
    and Proxy Sidecar Internal Latency in Nanoseconds (Client Response).
  • Dashboard: Fix Mesh-Instance-Relation metric Throughput.
  • Enhance associations for the Event widget.
  • Add event widgets in dashboard where applicable.
  • Fix dashboard list search box not work.
  • Fix short time range.
  • Fix event widget incompatibility in Safari.
  • Refactor the tags component to support searching for tag keys and values.
