I'm really annoyed ... by over 60 emails per day from my monitoring system!
If something of my infrastructure gets broken I really want to get notified.
But when a service flutters around, e.g. sometimes more and sometimes less CPU, it is good to know, but also very confusing when the whole e-mail inbox is full.
My solution is to separate very important and less relevant notifications by delivering them to different applications.

Juni 2019, der Monat, als es begann.
replicator: Panic: data stack: Out of memory when allocating 4294967336 bytes
Erste Reaktion: Verdammt, mein Mailserver stirbt, wenn Mails ankommen!
Zweite Reaktion: Brauche ich mehr RAM? --> nein!
Im folgenden eine etwas vereinfachte Darstellung meine Handlungen auf diesen Fehler, welche sich über mehrere Monate erstreckten.

In the course of migrating some services from very old openVZ machines I decided to use a powerful KVM Host with Proxmox to manage some applications in LXC and docker.
With my openITCOCKPIT installation, the migration to an LXC did not work using LXC default settings!
openITCOCKPIT needs to create own docker containers, but using docker in LXC wasn´t as easy as I thought.
After some annoying hours I got it working and in the end it wasn't that hard to set up :)
Now it´s my productive setup.
