Configuration reloading

[Dmitry]

Hi guys.

I'm always reload prom configuration with reloading of prom container. Is it normal? Or it's better to do it through post request.

We certainly recommend to either send a HUP signal or reload via the HTTP API (https://prometheus.io/docs/prometheus/latest/management_api/#reload) for reloading, rather than restarting the whole container. Depending on the size of your Prometheus, restarting it might take some time due to proper shutdown procedures and then replaying the write-ahead log (WAL) upon restart, so while it's not super costly, it's still disruptive if you do it often.
