The topic should state: " Understand the purpose of tools like
Nagios/mrtg/cacti in capacity planning"

I wouldn't dare to suggest Nagios or Icinga being part of an LPIC-2
exam as both could easily fill an exam on their own. I see that topic
more about getting an idea of which kind of properties exist and how
to measure them. Any simple tool would be sufficient for that task.
Just removing collectd would make 200.2 hard to test...
Do you have any other tool that you see more prominent / useful these
days? Or, given we drop collectd, would you prefer to extend the
"Awareness of monitoring solutions" part to feature knowledge and
comparison of Icinga2 and Cacti (or keep Nagios and MRTG included?)
and maybe spice in conceptual knowledge of SNMP? We should try to
avoid "submarines" (to quote Anselm) which consist of a tiny tiny
bullet in the objectives and open enormous discussions in training.

Ultimately, the context is "Capacity Planning." So we're actual
talking about collecting statistics. So instead of talking about
collectd, Nagios/Icinga, etc..., why aren't we actually talking
about what most of these tools use? [1]
I.e., RRDTools and its RRD files
Just saying, I'd focus on RRD and similar solutions, under the
objective's context, "Capacity Planning."

We can probably bikeshed this until the cows come home.
The advantage of collectd is that it is small, it measures
the most important
things, and it is reasonably easy to understand. Apart
from that, if you have
seen one monitoring tool you have more or less seen them
all, and everybody is
going to be using something different from everybody else
anyway.
If we put Nagios or Icinga on the exam, the next question
is going to be where
do we stop, since surely we don't want everyone to have to
know all the 94
Nagios plugins in Debian Jessie, but the 10 plugins that
you use are likely
going to be different from the 10 plugins that I use or
that Simone uses,
while each one of us will argue vehemently that *our*
plugins are the most
important ones and absolutely must be on the exam while
the others can get
lost
