Can you send your mrtg.cfg to me via PM

[scobi]

Hi! It's exactly the same as when we recreated it. Also should mention we've added a few more network devices, they all seem to be missing the rrd files showing bandwidth. POrt status is fine, just the rrd stuff is broken...

# cat mrtg.cfg

Code: Select all

HtmlDir: /var/www/mrtg
ImageDir: /var/www/mrtg
LogFormat: rrdtool
LogDir: /var/lib/mrtg
ThreshDir: /var/lib/mrtg

WorkDir: /var/lib/mrtg

Once it is at this stage we need to re-run the wizard, and the new config should be generated.

One this is before you do that make sure the permissions are as follows

Code: Select all

# ls -l /etc/mrtg/mrtg.cfg
-rw-r--r-- 1 apache nagios 9607 Mar 23 10:21 /etc/mrtg/mrtg.cfg

Ahhhh a bit different... How do I change permissions?

Code: Select all

# ls -l /etc/mrtg/mrtg.cfg
-rw-r--r-- 1 root root 137 Apr  1 09:40 /etc/mrtg/mrtg.cfg

Thanks!

[scottwilkerson]

Code: Select all

chown apache:nagios /etc/mrtg/mrtg.cfg

Then re-run the wizard.

Once it har run again, your /etc/mrtg/mrtg.cfg should contain additional items.

Thanks, I see the problem now! You'll have my a Nagios/Linux expert shortly!!!

Hey, I have quite a few rrd files from way back. SHould I delete these files before we start readding them? Just thougth I'd ask...

Thanks again Scott!

[scottwilkerson]

If you leave them, mrtg should use them, and add new info to them.

If you remove them it should create new ones automatically but lose historical performance data.

LOL

I think this is a "user" issue, sorta... I messed it up again, but I think I know a way to avoid this in the future. I think I'll need to rebuild it again, but thanks to this thread I got my list of action items... So here's what I did... Comments like "shame on you" are expected...

So, I re-ran the "Network Switch/Router" wizard and selected to scan ports. When the scan was complete, I unchecked all ports and only selected the ports I was interested in monitoring. HOWEVER, the bandwidth checkboxes along the right were all selected, so I get a TON of entries in mrtg.cfg file - I mean a ton.

Do I need to skip the port scan and just manually configure the interfaces to be monitored? I don't see how I can easily uncheck all the bandwith ports after the scan. Any other guidance would be great, if I need to rebuild it again, I'd like to only build it once more...

Thanks!

I modified the wizard to be more like it should have been. Upload the new one through
Admin -> Manage Config Wizards

Then, lets setup the /etc/mrtg/mrtg.cfg to the base as described above.

Now when you run the wizard you have an uncheck option for all 3 columns...
