comment How do StatsD and CollectD relate?
OK, so StatsD could be used to aggregate events from services which can then be fed to CollectD. (CollectD can then fed it to tools like Nagios and/or Graphite) But CollectD in itself has plugins to collect stats from services as well. So what differentiates using StatsD to do this instead of using a CollectD plugin? Just 2 different routes that accomplish the same thing?

comment Using Nagios Event Handlers to bring system back in correct state
Agreed. Coming from a software-engineering background, I directly have to think of state-machines (or something more formal like petrinets) to describe all possible states and the exact ways in which one state can lead to another. This reduces complexity a lot when implemented correctly. I'm not sure though if something like this has entered the realm of sysadmin or if it's even feasible. If I'm going to setup a 'Nagios > ansible feedback loop' the first simple rule would be that only 1 state-changing command may be executed at a time. Otherwise state is bound to get undefined due to racing.

Indeed, that wasn't clear from the question. Edited.
