Harvest Metrics for ONTAP API Request Volume

[vishanand-google]

Hi, we're trying to figure out to see the amount of API requests we're making to ONTAP, we're wondering if theres some Harvest metrics we could see regarding number of API calls.

This is in the context of a few recent bugs where we have overloaded ONTAP with API calls. we'd like to have some way of detecting if this is happening within ONTAP

hi @vishanand-google

I shared the following with BradleyK who I believe you were talking with?

The template below is what some folks have used to track the number of ONTAP API calls.

There is also the Harvest metric, metadata_collector_numCalls. The difference between what this template collects and metadata_collector_numCalls is one of point of view. metadata_collector_numCalls tells you the number of API calls the poller made to the cluster but won’t tell you anything about other client applications talking to the same cluster.

The ShowActiveByRequest template uses ONTAP’s API to track the number of active calls by interface. That API is cluster-centric and will tell you the number of active requests from all applications talking to the cluster.

name:                        ShowActiveByRequest
query:                       api/private/cli/security/session/request-statistics/show-by-request
object:                      show_by_request

counters:
  - ^^interface
  - ^^node
  - ^^request
  - active
  - total
  - filter:
      - interface=rest|ontapi
      - active=>0
