Grafana is a very useful tool for monitoring your own programs, discovering silly bugs, or simply looking at beautiful graphs :)
Another feature is "Alerts". These can be configured arbitrarily, whether high CPU load, too many errors in the log, or similar should trigger an alarm.
This post won't be about the alerts themselves, but rather about sending already configured alerts to Mastodon. These are called Contact Points in Grafana and initially don't offer Mastodon integration. However, this can be worked around with a few simple steps.
