How many service checks / host checks are you running on this machine? What are the specs of the machine?

Can you verify permissions on a few things and post the result -

Code: Select all

ls -l /usr/local/nagios/var
ls -l /usr/local/nagios/var/spool
ls -l /usr/local/nagios/var/spool/xidpe
ls -l /usr/local/nagios/var/spool/perfdata

Can you post your nagios.cfg and commands.cfg file here so we can review them?
I want to see if the settings are correct.

Also in this folder on your system
/usr/local/pnp4nagios/var/
The host-perfdata and service-perfdata files are really large and that could be the reason why this is failing.

Hi,


Should i delete or backup the host-perfdata and service-perfdata files ?

To be safe, you can make a backup of the files.

I checked the files and the commands that processes the performance data for both the host and service are missing from the commands.cfg file.
If you edit the commands.cfg file and change the following line from (Line 1708)

Code: Select all

       command_name    process-service-perfdata
to

Code: Select all

       command_name    process-service-perfdata-file
And change the following line from (Line 1713)

Code: Select all

       command_name    process-host-perfdata
to

Code: Select all

       command_name    process-host-perfdata-file
Save the file and restart nagios by running the following.

Code: Select all

service nagios restart
Wait about 20 to 30 minutes and see if the graphs start to populate again.

Lets check the log file and see what is happening.
Can you run the following command as root and port the output?

Code: Select all

tail -200 /usr/local/pnp4nagios/var/perfdata.log

I found this:
http://serverfault.com/questions/642174 ... nvironment
Apparently it's a Nagios 4 bug, where environment data used by pnp4nagios is not provided in sync mode.

Switching to bulk+npcd mode, solved the problem.
