MRTG Fails to Create .rrd in 2012R2.8b

[mikew]

After using the router/switch wizard to install a switch. No .rrd files are created in /var/lib/mrtg nor are .rrd files or xml files created in /usr/local/nagios/share/perfdata.

I have waited an hour so obviously it is not working.
* nagios has been restarted


Install version - new install
CentOS 6.4 64_bit
Nagios 2012R2.8b

When using the check command it shows that there are errors in mrtg.

Code: Select all

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

Yes, I believe the switch wizard was upgraded prematurely.

You can install the attached wizard and re-run and it should perform properly in 2.8b.

[mikew]

I replaced the switch wizard with a working version but I think the issue is with the program as it still fails. In addition it only reports on 3 ports when there are 20 working.

Before running it I cleaned up the mrtg.cfg file and made sure no rrd files were in the /var/lib/mrtg.

[scottwilkerson]

lets make sure your mrtg.cfg has this line toward the top

Code: Select all

WorkDir: /var/lib/mrtg

[lmiltchev]

Did you also cleaned up the "/usr/local/nagiosxi/tmp/" directory, according to the following document?

http://assets.nagios.com/downloads/nagi ... Router.pdf

What is the output of the following command?

Code: Select all

grep -i workdir /etc/mrtg/mrtg.cfg

[mikew]

The WorkDir /var/lib/mrtg did not exist in the file.

In addition, the /var/lib/mrtg is filled with images and html files? These files are being updated. Something is seriously wrong here.

Code: Select all

I added the workdir directory and tried again....

Code: Select all

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

So I removed everything, scan files, mrtg.cfg, /var/lib/mrtg/files, router wizard and installed a known good wizard and tried again. Now no workdir is added and I get this:

Code: Select all

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

I added the workdir and get this:

Mike, run the commands below and show us the output:

When do you use wizard to run switch/router - the background command changed the configuration in /etc/mrtg/mrtg.cfg

The problem is - when you run the wizard, the command remove/comment important lines in mrtg.cfg in last update in XI but the problem was solved in last version.

In addition, the /var/lib/mrtg is filled with images and html files? These files are being updated. Something is seriously wrong here.

@mikew - do you have this directive in the mrtg.cfg ?

Make sure the top of the mrtg.cfg file contains the following
