Hi team, we are trying to compute the overhead time of the platform. Meaning:

1 - (All workflows transition time / all workflows duration)

We use this PromQL query:

1 - 
  ( flyte:propeller:all:workflow:completion_latency_unlabeled_ms_sum
    + flyte:propeller:all:node:transition_latency_unlabeled_ms_sum
    + flyte:propeller:all:node:queueing_latency_unlabeled_ms_sum
    + flyte:propeller:all:workflow:acceptance_latency_unlabeled_ms_sum)
  / (flyte:propeller:all:workflow:failure_duration_unlabeled_ms_sum + flyte:propeller:all:workflow:success_duration_unlabeled_ms_sum)

The numbers we get seem a bit off ( around 50%). Is the PromQL query correct? What do you recommend we use to measure that overhead time ?

@Julien Bisconti overhead is always compared to the total runtime and that depends on the workload

yes please. We are struggling to understand the numbers we see

We can, a little too early for me right now
