[mrtg] Re: script problem

[Starkweather, Mike]

Robin,

Have you looked at the log file to see if the first line is changing when you
run your script?  The first line should just have three entries:  datestamp,
messages in, messages out.  If you don't see new values in the log then your
script output is not making it that far.

Another thing you can try is to turn on debugging in MRTG.  Look for
"$Main::Debug=0;" a couple of pages into the script and set it to 1.  It should
print the output of any external scripts so you can see what is happening.

Finally, though I have seen some evidence to the contrary, the documentation
calls for a four line input to MRTG:

Line 1 
	current state of the first variable, normally 'incoming bytes count' 
Line 2 
	current state of the second variable, normally 'outgoing bytes count' 
Line 3 
	string (in any human readable format), telling the uptime of the target.

Line 4 
	string, telling the name of the target. 

I usually give a 0 for line 3 and some string for line 4.

Hope some of this helps.
