What is the maximum latency for a metric with a timestamp?

[Rodolphe Ghio]

Hello,

I work with Prometheus and I saw that we could expose him to metrics with a timestamp. I did some tests and I saw that a latency of 1 hour worked but not two hours. Do you know the maximum latency for Prometheus to still accept metrics?

Best regards.

It's an hour, generally you should not be exposing metrics with timestamps though as it has issues such as not working with staleness.

If you're trying to record the time that some event happened, e.g. the last time that a job ran, then it's probably better to export the timestamp itself as a separate metric (value = Unix time seconds)
