.rrd file does not exit

[subashcbe]

Hi All,

We are unable to get the Interface bandwidth though MRTG. I am getting the below error:

Code: Select all

/var/lib/mrtg/10.56.240.11_2.rrd does not exist.

Nagios Version : Nagios XI 2014R1.3

The Hosts are added using the Network Switch Router Wizard.

Please let me how to to resolve this. We are getting the same for all the newly added hosts.

Let's check some permissions and try to find that file:

Code: Select all

ls -ld /var/lib/mrtg/
find / -name "10.56.240.11_2.rrd"

Hi,

Sorry for the delay. Please find the below output.

Code: Select all

[root@localhost ~]# ls -ld /var/lib/mrtg/
drwxr-xr-x 2 root root 36864 Jul 18 04:41 /var/lib/mrtg/

Code: Select all

[root@localhost ~]# find / -name "10.56.240.11_2.rrd"
[root@localhost ~]#

Is MRTG even running through your config file? Have you verified you have no major errors in the .cfg's that would possibly stop it from getting to that networking device? How many networking devices + ports on those devices are you monitoring that were set up with this wizard? What is the output of:

Code: Select all

LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg –check

Hi Slansing,

Please see the below output.

Code: Select all

[root@localhost ~]# LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg .check
[root@localhost ~]#

There are no major errors in the .cfg file. We are monitoring around 50 devices and all the ports. The port count varies from device to device from 2 to more than 30 ports.

Below is the output for "/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg"

Code: Select all

[root@localhost ~]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

The nagios config looks fine, but you mistyped a char in the MRTG check. It should be:

Code: Select all

LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg -check

Note the "-" instead of the "." before check.

Hi tmcdonald,

Was this a new install starting at 2014r1.3 or did you upgrade? If you upgraded, which version were you running before?

Also, was this a system you configured and then installed Nagios XI from source or was it one of our VMs? If you installed from source, what OS/version are you using? Was it a minimal install?
