[mrtg] Re: Problem with a shell script and Mrtg

[David Ashbrook]

All the scripts I've used with MRTG print out two lines with 0s on them after
the data.  I'm not sure if it's the correct way of doing it but it works.  You
can check out the "External Monitoring Scripts" section of the reference:

Hope this helps.

Subject: [mrtg] Problem with a shell script and Mrtg

Hello

I would appreciate it if some one could put me right with this

The shell script is as follows

#!/bin/sh

statname="Total Accounts"
uptime=unused

cd /home/full

statfull=$[`ls -l | grep -v ^l | wc -l`]

cd /home/guest

statguests=$[`ls -l | grep -v ^l | wc -l`]

stattotal=$[`expr $statfull+$statguests`]



echo $stattotal
echo $statguests

its output is as follows

[root at miles] ~# /usr/local/etc/mrtg/support/totalmail.sh
80
14
[root at miles] ~#

Which is perfect but when I run mrtg

I get the following

[root at miles] /usr/local/etc/mrtg/support# /usr/local/bin/mrtg 
/usr/local/etc/mrtg/miles.cfg
expr: syntax error
WARNING: Problem with External get '/usr/local/etc/mrtg/support/totalmail.sh':

eval into defined data
WARNING: Skipping Update of miles-user-clients, inlast is not defined
[root at miles] /usr/local/etc/mrtg/support#


The mtrg config is as follows

#

I would appreciate it if someone could assist me with this please thank you


Kind regards

Godfrey
