Troubleshooting Prometheus Grafana alert mute timings in Docker

Monitoring and Observability Grafana
1

Hi quick question. I am based in Europe/Athens and running a Prometheus/Grafana instance on docker (with docker compose, not relevant) so when I set up mute timings some alerts slip through for some reason. Should I be running the Grafana container in UTC or using local time and timezone is ok? What’s the rule there?

2

The main requirement is that your datetime data points be UTC

3

I think those are ok because the Grafana ui recognizes browser time at EEST (UTC+3) and the times on the graphs are ok (local time , no discrepancy or offset).

4

true. but it becomes an issue when you have users that span different timezones

5

browser level setting to local time cannot scale and will be hard to manage.

6

Actually I don’t have users across time zones.

7

I am just trying to avoid discrepancies

8

So you think I am following the book in this case?

Thanks , much appreciated.

10

what is the datasource on which alerts are based on the ones that slip through?

Same datasource for everything in that instance.
