XI Shows performance graph isn't running

According to the XI interface, the performance graph process isn't running. When I try to start it I get an error

When I go to the linux host, it shows the NPCD service is running:

Code: Select all

# service npcd status
NPCD running (pid 12353).
The /usr/local/nagios/var/npcd.log file shows no errors either:

What is the load on the server? It is possible, that once in a while it gets higher than the load_threshold of 10, specified in the "/usr/local/nagios/etc/pnp/npcd.cfg".

There are only 5 hosts configured within Nagios right now so the load is pretty low

Hm-m, this is strange. Have you restarted the server lately? Maybe npcd didn't start on reboot. What is the output of the following command?

Code: Select all

chkconfig --list | grep npcd

I just did a reboot and still the same issue

Lets make sure that it is not loading the daemon twice and causing multiple parent process issues:

Code: Select all

service npcd stop
killall npcd
ps -aef | grep npcd
service npcd start
Wait a few moments and then check the web UI again.

Run the following command:

Code: Select all

/usr/bin/php -q /usr/local/nagiosxi/cron/sysstat.php
then hit "Ctrl + C" to break out of it, and post the output.

Are you still receiving performance data on your graphs properly? This may be a glitch elsewhere. What version of XI are you running?
