[mrtg] Re: script question

[Mike Koch]

You need to feed MRTG with FOUR variables separated by a carried return, for
example :
273
57
String
String2

Their signification is in mrtg/doc/reference.html (middle page under
Target-> External Monitoring Script).

If you have only one integer to graph just be sure that your script outputs
something like :
273
0
0
0

Hope this helps !

Subject: [mrtg] script question



I was wondering if someone could help me with a problem using an
external script.

I have put together a bash script that uses snmpwalk to gather some info
on a USRTotal Control System.  And a perl script that actually uses the
bash file.  The perl outputs an integer that I want to keep track of in
an MRTG graph.
I have set up the mrtg.cfg file to look like this:

Target[mdm-use]: '/pathto/mrtgconfigs/usage.pl'
Title[mdm-use]: Modems in Use
MaxBytes[mdm-use]: 529
PageTop[mdm-use]: <H1> Modem Usage
 </H1>
 <TABLE>
   <TR><TD>System:</TD><TD>USR Rack</TD></TR>
   <TR><TD>Maintainer:</TD><TD></TD></TR>
   <TR><TD>Interface:</TD><TD>All modems</TD></TR>
   <TR><TD>Max Users:</TD>
       <TD>529</TD></TR>
  </TABLE>


When I run usage.pl it gives the output I want (which is a single
integer ie. 273), but the log files never change when I run it in MRTG.

Any help is greatly appreciated.
