I have a situation and, hence, a need for orientation:
I have Grafana 5.1.4 running (for a long time, don’t change what is running smoothly is my moto) with about 15 full-fledged dashboards with a lot of graphs, singlestat… panels, with alarms and so on
I just had a big situation with one of the dashboards : the alerting system in v5.1.4 does not re-send alarms, it only fires once (the “repeat” function was added after, on v5.4 I think) and consequently, we had a serious problem on one of the system monitored by the alerting system since the alarm was sent once and nobody paid attention to this first alert…
Now, I MUST upgrade Grafana to the latest version to allow for the use of the “repeat” alarm function.
Problem: I’m a NOOB (in Computer Science at least) and our IT guy is gone… I’m left temporarily alone to cope with this problem.
My question: what would be the step-by-step procedure to upgrade my Grafana server from 5.1.4 to current version without having to redesign all the dashboards and without loosing any configuration (like all the alerting system) ?
Thanks in advance, I’m in a pretty messed-up situation
