newbie question...
I have a service defined in my services.cfg file that looks like this:
define service {
use generic-service
host_name myserver
service_description PING
check_command check_ping!100.0,20%!500.0,60%
}
in my hosts file have "myserver" defined with an address tag:
www.myserver.com
when the check_ping command runs, does it check the ping status
against www.myserver.com even though I'm not
specifically specifying the host in the check_ping command?
The "check_ping" command in your service definition is *not* a reference
to the "check_ping" plugin, it's a reference to the "check_ping" check
command defined somewhere else in your config. Normally that command
will call a plugin (in this case, most likely check_ping) with some set
of arguments, which in most cases include the address of the host on
which the service was defined.

Re: [Nagios-users] trying to fix problem with excessive latency
Hi All, This is just a me too post to hopefully help others down the road! I have inherited maintenance of a medium-sized Nagios installation. We currently have 649 hosts and 5415 services. Our setup works nicely, with one exception: Nagios falls behind on host/service checks. Our usual latency once Nagios has been running for a while is about 190-200 seconds. Our Nagios host is reasonably powerful and isn't struggling; it seems that Nagios itself is limited somehow. We are similar in size 530 hosts, 3300 service checks with a service check latency of around 300 seconds and 350 for hosts. There are no obvious performance bottlenecks on our sever the closest thing to it for us was the CPU's ave of around 30% utilization across 4 procs with 4 GB of RAM. Our current configuration did not have any latency issues running Nagios 3.1.2, our latency issues started a couple of weeks ago with an upgrade to 3.2.2. >It looks like use_large_installation_tweaks did the trick. I could have sworn I tried that before; likely I set it to 0 instead of 1 or something foolish like that. We've avoided this in an effort to keep our configuration as plain as possible and because I remember reading that this was not expected to be effective unless you had something like 1000+ hosts and many more service checks. Apparently that is not correct, at least under 3.2.2. >Anyway, I wanted to test the individual components of large_installation_tweaks to see what helped. >* child_processes_fork_twice=0: latency drops from 149 to 18 This change took our latency from ~300s to .228 for services and ~350 seconds to .458 for hosts >* free_child_process_memory=0: latency drops from 149 to 0.6 I made this change with the 'child_processes_fork_twice=0' change still in place and saw no measurable drop in latencies. >* disabling summary macros in environment variables doesn't seem to be > individually configurable, but I expect that's disabled already by > enable_environment_macros=0. Did not do this, was not deemed necessary >So, thanks again to everybody who helped. Latency is now 0.35% of what it used to be. > >-Corey Ditto, this was a big help to us as well, thanks. -greg -- Beautiful is writing same markup.
