Icinga Benchmarks
I’ve seen a lot of questions about benchmarks, both here in the community
forums, but also from the Icinga support and developers.This made me want to create a spot where we can collect these, which is
going to be here!There is a kind of similar topic that is in the scope of “What kind of
environments are out there?”, but it doesn’t answer many questions on the
performance side:
Indeed - that’s all very well from an anecdotal point of view, but too much to
read for someone looking for a convenient summary / comparison.
So I would like to ask for your input on how we should define some
benchmarks and get some results from different environments!
I would say the most important aspect is that the information has to be
tabular, so that viewers can compre one entry with another easily and
quantitatively.
We probably can’t define all the parameters which are important in the table at
the start, so they’ll change a little over time, but I think the important
part is to make sure we ask people for numbers which can be compared like-
for-like to give newcomers an opportunity to see “this installation is coping
with X servers and Y services based on Z hardware, so that gives me a good
approximation to what I’ll need”.
I think it’s also important to think about how Icinga2 actually works, in
terms of Masters, Satellite and Agents, because one Master talking to 50
Satellites, each talking to 500 Agents, is going to have a very different
workload from one Master trying to talk to 25000 Agents…
I think the point I’m getting at there is that we need to know about directly
connected Agents - the indirect ones are a lot less important to system load
(although they contribute to bandwidth).
Do you have any ideas at all about how people could actually submit this type
of information, and then be able to update it as their systems change in the
future?
It feels to me like it needs to be some sort of “semi-private wiki”, where
anyone can add data to it, but only that person / organisation can edit their
data later on. Not sure how that can be done…
Anyway, those are my thoughts for the time being; once I have a bit more time
I’ll see if I can think of suggested measurements for people to supply their
values for.

Antony.
