pnp4nagios installed correctly but isn't populating rrd data

[majed]

pnp version: pnp4nagios-0.6.24
nagios 4.0.8
system 3.14.16-gentoo

error message:

Code: Select all

perfdata directory "/usr/local/pnp4nagios/var/perfdata/terminal" for host "terminal" does not exist. <a href="http://docs.pnp4nagios.org/faq/5">Read FAQ online</a>

in apache error log :

Code: Select all

File does not exist: /usr/local/nagios/share/images/logos/base, referer: http://10.33.0.7/nagios/cgi-bin/status.cgi?host=all

in nagios.log:

Code: Select all

Warning: File '/var/nagios/perfdata.log' could not be opened - service performance data will not be written to file!

Why isn't pnp4nagios creating rrd files?
i have cacti installed and it is using rrd and graphs show so why does it work for cacti but not for nagios on the same system? i also have ndo2db installed.

Did you read the FAQ entry linked in the error message?

perfdata-dir-for-host

PNP was called with a host in the URL.

Example:

http://<nagios-server>/pnp4nagios/graph?host=<this-host>

The resulting path to the perfdata directory could not be found.

The path is shown in the error message.

var/perfdata/<this-host> will be created by process_perfdata.pl when it processes performance data for this host.

If this directory does not exist there are several possible causes:

Passing an incorrect host name in the URL
The host has no valid performance data
None of the services has valid performance data

Is the host returning valid performance data?

[majed]

well the path is

Code: Select all

/usr/local/pnp4nagios/var/perfdata/terminal

and the perfdata directory is empty.
the service or host is for ping which has valid perfdata.

Code: Select all

Performance Data:	rta=23.295000ms;5000.000000;5000.000000;0.000000 pl=0%;100;100;0

mrtg is not displaying graphs either, no rrd files in it's directory either. i suspect rrdtool is just generating rrds for cacti and not working for nagios and mrtg and ndo.

It could be permissions related:

Code: Select all

ls -la /usr/local/pnp4nagios/var/perfdata/terminal
ls -lad /usr/local/pnp4nagios/var/perfdata/
ls -lad /usr/local/pnp4nagios/var/
grep nag /etc/group

[majed]

Code: Select all

 ls -la /usr/local/pnp4nagios/var/perfdata/terminal
ls: cannot access /usr/local/pnp4nagios/var/perfdata/terminal: No such file or directory

Code: Select all

gentoo ~ # ls -lad /usr/local/pnp4nagios/var/perfdata/
drwxr-xr-x 2 nagios nagios 4096 Aug 21 03:11 /usr/local/pnp4nagios/var/perfdata/

Code: Select all

gentoo ~ # ls -lad /usr/local/pnp4nagios/var/
drwxr-xr-x 6 nagios nagios 4096 Aug 21 03:11 /usr/local/pnp4nagios/var/

Code: Select all

gentoo ~ # grep nag /etc/group
nagios:x:1000:apache
nagcmd:x:1001:nagios,apache,cacti

i haven't changed the default owner, group.

Could you post your nagios.cfg? At this point, it may be an issue with the performance commands as the permissions and groups look fine.

[majed]

apparently nagios 4 and pnp4nagios don't work in sync mode. Who has the same problem or would like to see the solution visit

Thanks for the heads up. Most often, I see people use bulk mode with npcd.
