I am generating a Histogram using a prometheus client. The metric name is retrieve_stripe_subscription_latency_ms
. Since Histogram generates additional metrics with suffixes _sum
and _count
, can I calculate the average using the below query in Grafana?
sum(retrieve_stripe_subscription_latency_ms_sum)/sum(retrieve_stripe_subscription_latency_ms_count)
I think official Prometheus documentation address this. Having your metric name:
To calculate the average [...put here a metric meaning...] during the last 5 minutes from a histogram or summary called
retrieve_stripe_subscription_latency_ms
, use the following expression:rate(retrieve_stripe_subscription_latency_ms_sum[5m]) / rate(retrieve_stripe_subscription_latency_ms_count[5m])
