Hi guys,
what @MarcusCaepio wrote is what I thought, too. We use it very much in our environment and (until now) I can not think of an alternative way to solve some of our “problems” withou eventhandlers.
I just commented beneth the video from Icinga / nilberg when it was released. But somehow my comment was deleted.
But I try to recreate it from my memories.
For our team and many of our customers eventhandlers are very important.
Unfortunately some customers use quite stupid and instable software that can not run and live without being continously restarted when certain errors occur. In those cases we use some self written eventhandlers.
Like when a specific error occurs or port is down which we all monitor, an eventhandler kicks the server itself or the software and restarts it.
We also use them to acknowledge a host or a service automatically based on certain service states or outputs.
We migrated most of them from icinga1 to icinga2 so it might have grown historically.
But at least until now we do not know of an alternative way to solve these problems.
Maybe you could enlighten us in the dark
