Troubleshoot problems with NAGIOS/ICINGA-PNP4 not displaying graphics

Recently in the use of Icinga deployment monitoring, after the use of ICINGA-PNP4 deployment, the inside of the display of historical data graphics display, error:

LocalHost directory does not exist, or localhost directory is empty

After research, the final confirmation is because in the Icinga configuration file icinga.cfg, does not open the option about PerfData, resulting in Icinga will not store historical data to the specified directory, just open it all, restart the Icinga service, you can display historical data graphics.

For perfdata configuration items, remove the previous # as follows:

958:process_performance_data=1

972:host_perfdata_command=pnp4-process-host-perfdata
