[mrtg] Re: MRTG suddenly stopped working

[PAUL WILLIAMSON]

Is this on a *nix machine?  Usually failures go to 
root at localhost.  Check with either pine or mail.

If that is not the case, run the script by hand.  The 
very first thing to do is what you've already done.
Verify that one OID will work with the manual setup.
Next is to run mrtg against the config to make sure 
no errors get returned.  I'm guessing either the 
log is messed up or time got changed somehow, 
preventing things from getting recorded correctly.

I had a MRTG config up and running monitoring CPU usage.  Here is my  
MRTG v2.9.17 config file:

Target[cpu]:  
.1.3.6.1.4.1.2021.10.1.5.1&.1.3.6.1.4.1.2021.10.1.5.1:public at freya.wavef 
ront.ca
RouterUptime[cpu]: public at freya.wavefront.ca
MaxBytes[cpu]: 100
Title[cpu]: freya.wavefront.ca CPU Load
PageTop[cpu]: <H1>Total CPU Load %</H1>
Unscaled[cpu]: ymwd
ShortLegend[cpu]: %
YLegend[cpu]: CPU Utilization
Legend1[cpu]: CPU in % (Load)
LegendI[cpu]: CPU Load*
Options[cpu]: growright,nopercent,nobanner,nolegend,noo
Colours[cpu]: RED#FF0000,RED#FF0000,RED#FF0000,RED#FF0000

I worked al day and now I am getting a flat line 0 plot.  The MRTG page  
gets generated and the last update time shows that it's running.  I  
have a disk usage config

Here is the corresponding snmpget result:

[freya:/var/log] tappind# snmpget freya.wavefront.ca public  
.1.3.6.1.4.1.2021.10.1.5.1
enterprises.ucdavis.laTable.laEntry.laLoadInt.1 = 5

Is there any way to track this down?  is there a MRTG error log?

Any ideas out there?

Thanks,

Dan
