Hey all, I'm working on monitoring the network interface on one of my servers with MRTG and I have again hit a snag. According to the instructions here:

http://www.sans.edu/student-files/prese ... _notes.pdf

I need to enter the OID for the label of the network interface. I searched for the correct OID, found it and put it in my config file:

Code: Select all

Target[netDictum2]:.1.3.6.1.2.1.2.2.1.2.65539&.1.3.6.1.2.1.2.2.1.2.65539:[email protected]
MaxBytes[netDictum2]: 1000000000
Options[netDictum2]: growright, gauge, nopercent
YLegend[netDictum2]: Dictum2 Bandwidth Usage
Legend1[netDictum2]: Outbound bytes/sec:
Legend2[netDictum2]: Inbound bytes/sec:
Legend3[netDictum2]:
Legend4[netDictum2]:
LegendI[netDictum2]: Out :
LegendO[netDictum2]: In :
Title[netDictum2]: Dictum2 Bandwidth Usage
PageTop[netDictum2]: <H1>Dictum2 Bandwidth Usage</H1>

However, when I run the code I get the following error message:

Code: Select all

root@FreeNag:/usr/home/jobee/Config # /usr/local/bin/mrtg /usr/home/jobee/Config/mrtg_192.168.2.29.cfg
2014-04-05 15:38:31: WARNING: Expected a number but got 'HP Network Team #1'
2014-04-05 15:38:31: WARNING: Expected a number but got 'HP Network Team #1'

Use of uninitialized value $outlast in pattern match (m//) at /usr/local/bin/mrtg line 1047.
root@FreeNag:/usr/home/jobee/Config #

Notice the two Warning lines saying they got "HP Network Team #1." According to the instructions that tells me I'm using the correct OID but I'm guessing that MRTG is looking for a numerical value. So, the error message tells me I'm wrong but it's also telling me I used the correct OID for that interface. Any ideas? Suggestions? Recommendations?

Thanks,

I would pose the same question I did in your other post regarding mrtg support, only because this doesn't seem to be a nagios specific issue and I think they might be able to get to the root of the issue a little quicker. Certainly feel free to provide more information, if you think we are the best people to look at it, we are definitely happy to help either way.

Hi sreinhardt, I just read that other post. Like I said in that other post I was hoping to get an answer here because the MRTG support options are less user-friendly than they are here.

Thanks,

Joe B
