Understood @Cihan_Tunali - as I mentioned before I am not a MongoDB expert therefore I can’t explain why latency would be relatively zero through active records being written, then spike significantly during a period of zero inserts.
I know you are waiting for a fix related to mongodb_exporter in PMM-7116 - have you tested deploying our latest in PMM 2.14 ? We made significant changes related to swapping out Prometheus for VictoriaMetrics.
