If you enable performance data then you can implement a script to take
this data and process it however you wish - for example, some folks
use the nagiosgraph package to produce rrd'style graphs from said
performance data. I, on the other hand, take the performance data and
store it away in a firebird database.

For example :-

define command{
        command_name    process-service-perfdata
"$HOSTNAME$||$SERVICEDESC$||$SERVICEOUTPUT$||$SERVICEPERFDATA$"
        command_line    /usr/local/nagios/perfdata/insert.pl
}

where "insert.pl" is your own homegrown perl script to extract the
numbers from the perfdata log file (which you will find in
/var/spool/nagios/perfdata.log)


You also need to add the following to your main nagios.cfg file :-

process_performance_data=1
service_perfdata_file=/var/spool/nagios/perfdata.log
service_perfdata_file_processing_command=process-service-perfdata

hope this helps.

bright blessings,
Mark
