Thanks found it - I removed all of the interface sections and ran LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/conf.d/172.25.40.21.cfg –check and got the following errors:

Use of uninitialized value $dir in concatenation (.) or string at /usr/bin/mrtg line 2658.
Use of uninitialized value $dir in concatenation (.) or string at /usr/bin/mrtg line 2676.
Use of uninitialized value $dir in concatenation (.) or string at /usr/bin/mrtg line 2692.
ERROR: "WorkDir" not specified in mrtg config file

Which confuses me because there are no line number 2658, 2676, or 2692 and the WorkDir line is commented out, and if I uncomment it it points to /home/http/mrtg - but I do not have a /home/http/mrtg folder....not sure where to go now?

Can you run the following command and show us the output in code wraps?

Code: Select all

cat /etc/mrtg/mrtg.cfg

Here it is:

You cannot run these configs standalone, you would need to run the following

Code: Select all

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

Ok, i ran that command and got some errors - the errors are for other switches (some that don't actually exist anymore) but are not showing the switch that I am working with. In the pdf it says if there are no errors then you are good to go, does htis mean because the switch I am working with is not listed in the errors that I am indeed good to go?

Code: Select all

Well are you getting the data for your switch that you are using in XI now? Should probably end up removing the ones that are no longer used in XI just to keep it clear but it looks like it's doing an authentication check when it reads the configs and the errors are just if it fails... in theory if you don't have any errors for the switch you are trying to monitor it should be okay as long as MRTG is running.

Ok, dumb question but how would I know if MRTG is running?

I ran "ps aux" but do not see any processes that remotely look like mrtg....

MRTG is run on a 5 minute cron job. Probably the easiest route would be to look at either the cron log, or verify that the files in /var/lib/mrtg/ are up to date, as these are the files that mrtg is storing results in.

One thing to note on your previous comments that some of the devices erroring are not in existence anymore or that you do not care to monitor them. I would highly suggest removing the configurations from /etc/mrtg/conf.d/ as those delays will eventually if not already, cause issues as you increase the number of devices that mrtg monitors.
