Update (c) 2010 Frank4DD<support[at]frank4dd.com>
This plugin checks nagios performance data by parsing the nagios status.dat file, e.g. in /usr/local/nagios/var/status.dat. This is helpful to correlate the Nagios configuration size with the OS performance to identify upcoming hardware bottlenecks for Nagios.
Because it depends on being able to read the status.dat file, it runs locally on the Nagios server itself.

-v, --verbose
print extra debugging information
-h, --help
print this help message
-s, --service_latency
checks the service with the max execution latency
-o, --host_latency
checks the host check with the max execution latency
-p, --hostcount
check number of monitored hosts
-r, --servicecount
check number of monitored services
-w, --warn=INTEGER
warning threshold
-c, --crit=INTEGER
critical threshold
-f, --file
provide an alternate file path to status.dat
Below is an example of the plugin definition in the Nagios command.cfg file.
# Check the # of monitored hosts w. check_nagiostats.pl
define command{
command_name check_nagiosconf
command_line $USER1$/check_nagiostats.pl -w $ARG1$ -c $ARG2$ -p
}
The plugin with its most basic use, counting the number of monitored hosts
susie: ~ # cd /srv/app/nagios/libexec # ./check_nagiostats.pl -w 50 -c 100 -p OK: 3 Nagios host checks|count=3
The plugin with -o, checking the max execution latency for host checks.
# ./check_nagiostats.pl -w 50 -c 100 -o OK: max latency: =0.000 avg latency: 0.000 min latency: =0.000|max=0.000s;50;100 avg=0.000s;50;100 min=0.000s;50;100
