Edit /usr/local/nagios/etc/nagios.cfg

service_perfdata_file_processing_interval=15

host_perfdata_file_processing_command=process-host-perfdata-file
service_perfdata_file_processing_command=process-service-perfdata-file
Edit /usr/local/nagios/etc/objects/commands.cfg. Choose the bulk mode with npcd for performance data processing
define command{
command_name process-service-perfdata-file
command_line /bin/mv /usr/local/nagios/var/service-perfdata /usr/local/nagios/var/spool/perfdata/service-perfdata.$TIMET$
}

define command{
command_name process-host-perfdata-file
command_line /bin/mv /usr/local/nagios/var/host-perfdata /usr/local/nagios/var/spool/perfdata/host-perfdata.$TIMET$
}
Then, edit /usr/local/nagios/etc/objects/templates.cfg
define host{
...
action_url /nagios/pnp/index.php?host=$HOSTNAME$
...
}

define service{
...
action_url /nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$
...
}
In normal, view the page in new page. If don't like, edit /usr/local/nagios/etc/cgi.cfg
#Normal
#action_url_target=_blank

#Use the same frame
action_url_target=_self

In case, performance data is here, but get this error - "Directory /usr/local/nagios/share/perfdata/hostname not found."

Go to edit /usr/local/nagios/etc/pnp/process_perfdata.cfg
  • Set LOG_LEVEL to be debug - 2
  • It is running default setting if this file isn't here. You can simply rename / copy process_perfdata.cfg-sample
  • After that, the log is in /usr/local/nagios/var/perfdata.log
If still can't, check
  • npcd service is running
  • /usr/local/nagios/etc/pnp/npcd.cfg is here
