Comment (by anarcat):

 just checked and those nagios plugins are already provided by the ganeti
 puppet module, just a matter of deploying the things.

 the trending/graphing aspect is still TBD.

New description:

 we're migrating everything into ganeti, but maybe there's some extra
 monitoring we could think about, as ganeti is way more knowledgeable about
 its own internals than libvirt was. or at least that's the feeling I get.

 some ideas:

  * we could have a nagios plugin that checks for N+1. riseup has something
 like this
  * we could have a grafana dashboard that shows us the state of the
 cluster. we already have the main dashboard which we can set to show only
 the ganeti cluster

 The current memory view goes about like this:

 [[Image(snap-2020.04.03-17.33.23.png,700)]]

 I'm not sure how we could improve this, but it seems to me having global
 (and/or per node?) memory, CPU, network and disk  usage would be a great
 improvement as well.
