* Default Mode

/etc/nagios/nagios.cfg

 process_performance_data=1
 service_perfdata_command=process-service-perfdata

/etc/nagios/commands.cfg

define command {
  command_name    process-service-perfdata
  command_line    /usr/bin/perl /usr/libexec/pnp4nagios/process_perfdata.pl
}

define command {

  command_line    /usr/bin/perl /usr/libexec/pnp4nagios/process_perfdata.pl -d HOSTPERFDATA
}


* Bulk Mode

/etc/nagios/nagios.cfg :

process_performance_data=1
#
# service performance data
#
service_perfdata_file=/var/spool/nagios/service-perfdata
service_perfdata_file_template=DATATYPE::SERVICEPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tSERVICEDESC::$SERVICEDESC$\tSERVICEPERFDATA::$SERVICEPERFDATA$\tSERVICECHECKCOMMAND::$SERVICECHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$\tSERVICESTATE::$SERVICESTATE$\tSERVICESTATETYPE::$SERVICESTATETYPE$

/etc/nagios/commands.cfg :

define command{
        command_name    process-service-perfdata-file
        command_line    $USER1$/process_perfdata.pl --bulk=/var/spool/nagios/service-perfdata

        command_line    $USER1$/process_perfdata.pl --bulk=/var/spool/nagios/host-perfdata
 }


* Bulk Mode with NPCD

npcd daemon needs to be started :
service npcd start
chkconfig npcd on

The configuration is identical to the bulk mode except for the used command.

/etc/nagios/commands.cfg :

define command{
        command_name    process-service-perfdata-file
        command_line    /bin/mv /var/spool/nagios/service-perfdata /var/spool/pnp4nagios/service-perfdata.$TIMET$
 }

define command{
        command_name    process-host-perfdata-file
        command_line    /bin/mv /var/spool/nagios/host-perfdata /var/spool/pnp4nagios/service-perfdata.$TIMET$
 }


* Nagios integration

/etc/nagios/hostextinfo.cfg :

define hostextinfo {
    host_name localhost
    action_url /pnp4nagios/graph?host=$HOSTNAME$
    }
