Yes, this is the process pool code, although additional changes has to be
made in order to solve the bottleneck problem with the named pipe for
submitting commands and passive
There are several tweaks one can do to make Nagios more or less saturate the
CPU, but none of them are enough if the number of checks rise above a certain
level. We've noticed that we can run about 60K service-checks so long as we
don't have many state-changes in the network. That's not nearly

Hi list,
Several times I'm asked about Nagios latency when the number of services go
over a certain number.
Is there any tweak to have nagios scale checkings more than it would after
tweaking every configuration option for boosting performance?
It seems that nagios don't do the best job at

It seems that nagios don't do the best job at taking the hardware to
its real limits.
When I have more than, say, 10k checks, I start seen check latency
rises and there just isn't anything that could be done, even
distributed monitoring

So, I've just gone through this, and the single greatest bottleneck I
had to deal
Patch can be found here:
http://github.com/netoisstools/Nagios-3-Patches/blob/master/events.c.patch
Download it to your nagios source directory then run
patch -p0 events.c.patch
if you use the patch, make sure to set use_large_installation_tweaks
to 1 as it will only skip the sleep time if
I spent couple weeks playing with 3.2.1 and found that it performs very well
with active checks (6500+ in 5 min at 1-2 sec latency max) but could not
pass 5000 passive checks on the master server.
When switched to 3.2.0, it processes 7300-7500 passive checks out of 8055 at
0.2 sec latency using

Marcel, are you using nagios2.x or 3.x? I'm testing out 3.2.0 and find
that nagios3.x performs pretty well, being multi-threaded and all.
From other comments, there are presently delays inherent in various
tasks. So does the 3.2.0
I'm trying to get 80k service checks w/ about 1500 hosts and would be
very interested in testing your patch, what was the name of the post
you made so I can give it a whirl?
