One simple thing that might help is just run vmstat for a couple minutes:
vmstat 5
That can help show if you are hitting some bottlenecks. Are you using a lo=
t of macros in your configs?

roblem
Hi everybody,
I=B4m testing Nagios and Gearman / Mod_Gearman. I=B4d like to change NSCA w=
ith this new approach, as it seems easier to configure and has a lot of adv=
antages. Besides, NSCA and Nagios freshness mechanism have some problems.
Gearman and mod_gearman are working well. I have 30000 hosts and 60000 serv=
ices, and it is increasing!
Now I=B4m having problem with Nagios performance, that eats 100% of CPU and=
the host and service latency is very big, around 300 seconds. I think that=
this a Nagios problem, as the gearman_top shows the Job Wainting queue emp=
ty almost all the time. It seems that Nagios do not send the active checks =
all the time, an once in while it sends a burst of active checks.
I have a physical central server, running RHEL, with 4 GB of ram, Intel(R) =
Xeon(R) CPU E5504 @ 2.00GHz (8 CPUs). For the workers I have 9 virtual ser=
vers running RHEL too.
I've already set the Nagios parameters to large environment, as recommended=
in the documentation, but it made no difference. Thanks.
Nagios Parameters to large environment:
- use_large_installation_tweaks=3D1
- enable_environment_macros=3D0
- max_concurrent_checks=3D0
- check_result_reaper_frequency=3D10
Could someone help me? How can I improve Nagios performance to make active =
checks faster?
Thank you very much.
