Problem

When using the Rest/RestPerf collector for ontap, metrics are missing in certain clusters as shown in the image.
This does not occur in all clusters, but occurs in clusters with a large number of resources such as SVMs or volumes.
(e.g. volume: 1000 or more, svm: 65 or more)
Also, it does not occur in case of Zapi/ZapiPerf collector.

Thank you for your confirmation.

@r-kw1-bus Could you please provide the names of the metrics that have these gaps? Could you upload the Harvest logs at the following link: https://upload.nabox.org/pybe-jono-pezo?

You can refer to the documentation here for log collection: Log Collection Guide.

@rahulguptajss Sorry for the late reply.

Are you still experiencing this issue?

Yes. The problem is still ongoing.

Could you please provide the names of the metrics that have these gaps?

Almost all metrics have gaps.
The extent of the gap varies slightly depending on the metric.

We have also created our own exporter that uses the Rest API in addition to harvest, but we have not had the same problem with it.

Could you upload the Harvest logs at the following link...

I'm sorry.
Because the device in question belongs to the company, I cannot upload the logs immediately for security reasons.
I will contact you again and upload the logs once there are any progress.

Sure, could you please provide your Harvest version?

Additionally, several improvements have been made in our latest release, which you can find here: Harvest 24.11.1. Please update to this version, and if the issue persists, share the logs with us.
