[mrtg] Same config, differing results...

Wed Nov 19 21:15:17 CET 2014

It has been a while since I looked at config files, so I could be wrong, 
but....

isn't the default ( [_] ) in effect from the moment it is seen?  And doesn't 
this mean that you are using the default of gauge when you define user-eth1, 
and only change the default _after_ this target is defined?

To test this hyphotesis:  move the line  "Options[_]: bits, counter" up, so 
that it is in front of  Target[user-eth1]: 12:xxxxpublic at 192.168.0.77:

Furthermore I wonder why you didn't write "Options[user-eth1]: bits, 
counter" in the first place.

Thank you Wrolf, regarding the 'gauge vs counter' configuration. I have 
modified the cfg as shown below. I left the gauge option enabled globally as 
I have other devices monitored on the device (disk space, CPU load, etc.), 
But 'counter' is enabled locally for that interface.

Previously, I had tried deleting the log file entirely for that interface. 
The same problem recurred. So, this time I took your advice and copied the 
log file from the 'working' test server to the 'faulty' production server. 
Sadly, I'm back to square one. From the moment the log file was copied, 
moving forward, the saw-tooth line began growing again.

Ug!

Are you sure you want it to be a guage value – I believe the default is 
counter.

You may want to copy over the .log or .rrd file from the working box.

I have a test (virtual) Debian server that I use for testing new 
applications, configs, etc. before they are deployed to my production Debian 
server. MRTG is amongst the apps that I use the virtual server for.

Currently I am using the identical cfg file to monitor bandwidth on a 
Windows 7 wireless network adaptor on my laptop. On the test server, the 
graphed results are exactly what I intended. However, the exact cfg file on 
the production server
 produces dramatically different results. On the production environment, the 
graph is a continually growing saw-tooth graph that almost appears to be 
showing the uptime of the interface. If, after a few hours, I turn off the 
wireless interface and turn it back
 on, the graph drops to zero and the saw-tooth begins again. Conversely, on 
the test server, the bandwidth logs continue to be logged and displayed 
exactly as intended.

Two servers, both running the same OS (Debian 7.7), both running the same 
version of MRTG (2.7.14) and both running the same config for the intended 
interface (below). What am I possibly missing?

Thanks, in advance, for any suggestions!
