NSCLIENT output

Hi William,

I use a simple shell script to graph CPU usage in MRTG. I do the same
for lots of things by the way: memory usage, sql connections, oracle
backlog,... hell, I even graph the Warcraft III levels and scores of
me and some of my colleagues with it :-)

This is what I use for CPU load:

[root at netsaint logging]# cat cleanload.sh 
#!/bin/sh
hostname=$1
uptime=`/usr/local/netsaint/libexec/check_nt -H $1 -p 1248 -v UPTIME |
cut -d: -f2`
stat=`/usr/local/netsaint/libexec/check_nt -H $1 -p 1248 -v CPULOAD -l
5,80,95,60,80,95,1440,80,95 | cut -d\% -f1 | awk '{print $5}'`
if [ "$stat" = "out" ]; then
        stat=0
fi
if [ "$stat" = "" ]; then
        stat=0
fi
if [ "$stat" = "seconds" ]; then
        stat=0
fi
echo $stat
echo $stat
echo $uptime
echo $hostname

In mrtg.cfg this is:

### System: servername

Target[servername]:`/usr/local/netsaint/logging/cleanload.sh
servername`
MaxBytes[servername]: 100
AbsMax[servername]: 2500
Options[servername]: gauge, unknaszero, withzeroes
WithPeak[servername]: w
Title[servername]: System load stats for servername
BodyTag[servername]:<BODY BACKGROUND="" BGCOLOR="#F7FFFF">
PageTop[servername]: <H1>Load for servername</H1>
Legend1[servername]: system load average ( % )
Legend2[servername]:
Legend3[servername]: maximal 5 minute system load average (% )
Legend4[servername]:
LegendI[servername]: load
LegendO[servername]:
YLegend[servername]: loadavg (%)
ShortLegend[servername]: / 100


Hope it helps.

Kind regards,
Tom
