Have you tried to re-set the backend password? Not sure that's the problem here though.

The .rrd files for these graphs are located in /usr/local/nagios/share/perfdata
You should make sure the perms are nagios:nagios/777:666. You should also make sure the .rrd files are being updated and that the .xml files contain sensible data.

I'll look further as to what I'd do to debug this.

That is perms like so:

Hi The xml file are arriving and contain good data but the rrd files are not getting updated as you can see from the date stamp.

I believe the process responsible for this is located in /etc/cron.d/cacti that calls /var/www/cacti/poller.php every 5min as the user cacti. However I was informed that we migrated from using Cacti to using pnp.

I'll look into this further.

the files /etc/cron.d/cacti and /var/www/cacti/poller.php don't exist on the server

The only files with cacti in the name are as follows ................

[root@oracle-mon cron.d]# find / -name '*cacti*'
/tmp/xi/13-cacti
/tmp/xi/nagiosxi/httpd.cacti.conf

Hi I have been looking at the pnp bits it would appear that we have an invalid device /dev/.udev/failed/devices@pnp0@00:04 ???

That's the Plug and Play bus. I'd guess it's for the old ISA PnP stuff.

HI,

Sorry I dont understand, how can I debug the issue and resolve the problem.

This isn't a Cacti issue, as Cacti isn't installed on the box. All graphing is handled by PNP, so its likely a PNP issue. Try this:

Enable the log_level option in the following file: /usr/local/nagios/etc/pnp/npcd.cfg

Restart PNP with the following command:

service npcd restart

Examine the /usr/local/nagios/var/npcd.log file for error messages
