2022-03-18 Using grafana for alerting too
I've been playing with grafana for about a year since starting with updating my statistics gathering and I keep seeing new options and updates in grafana.

Grafana recently got some new options for alerting and I am trying a few of those. Alerts for things that are a real problem and can cause other problems are a good start. Based on some earlier problems I keep an eye on some filesystems that are over 90% full.

Today I read Three DDoS attacks on my personal website found via Three DDoS attacks on my personal website : r/homelab reddit and this made me wonder about overloads on my webserver. The easiest way to detect problems with web serving I could think of is to look at the queue size in haproxy which is monitored in influxdb/grafana anyway for nice graphs of website traffic.

I did have a time with too high queues for backend webservers. But that was when the backend server was completely broken due to a filesystem problem so that was a logical reason.

It would be nice if I could iterate alerts, like 'for the root filesystem of every monitored system'. Or at least copy them changing only the system name in the rules and alerts.
