Dear All,


I want to create MRTG Graph from Etinc Bandwidth Manager. Please can anyone
assist me on that.


On the main menu of our Bandwithd Manager's Graphical User Interface (GUI),

You are using a Nagios plugin in MRTG.  While some Nagios plugins have an
'MRTG Mode', it seems that this one doesn't (or if it does, you've not
enabled it).   

A Nagios plugin should output one line of text, with a message followed by
'|' and the perfstats data as var=value sets.  It then exits with a status
of 0,1,2 or 3 depending on the tests. 

An MRTG plugin should output 4 lines of text; two with numbers and then two
more optionally holding uptime and system name (though these can be left
blank).  It should always exit with status 0. 

In order to make this work with MRTG, you'll need to modify the plugin to
output MRTG status, or use a wrapper script like this: 

# check_nwstat_mrtg 
perfstat=`/usr/lib/nagios/plugins/check_nwstat $* | cut -f2 -d '|'` 
val=`echo "$perfstat"|sed 's/^.*=//'|sed 's/;.*//'` 
echo $val 
echo $val 
echo '' 
echo "$perfstat" 
exit 0
