Hi All, do we have metric that is similar to CMD: "statistics cache flash-pool show"
To get the Read-hit, Write-hit, and Cache Used data?

@midnight token
Harvest has 5 panels in Aggregate dashboard for flashpool object metrics fetched from https://github.com/NetApp/harvest/blob/main/conf/restperf/9.12.0/wafl_hya_per_aggr.yaml. You can explore them.
Also, Could you share the response of below rest perf call so we can investigate further of required counters.
**Note: **You need to replace USER, PASS and CLUSTER_IP accordingly.

curl -sk -u USER:PASS ' https://CLUSTER_IP/api/cluster/counter/tables/wafl_hya_per_aggregate/rows?return_records=true&fields=*’ > flashpool_perf.json

@sweet steeple I tried with this, and found that the metric don't have label aggr, so the dashboard cannot show because they have aggr label in filter.
From the API, the aggr output is hya_aggregate_name
We should alter the wafl_hya_per_aggr.yaml

hya_aggregate_name => aggr
rather than
hya_aggr_name => aggr

@midnight token Template seems correct.

https://github.com/NetApp/harvest/blob/main/conf/restperf/9.12.0/wafl_hya_per_aggr.yaml#L7

Could you please recheck?

Noted, maybe they are using an older version of Harvest.
