Re: Graphing System Load MRTG

[Jobst Schmalenbach <jobst@xxxxxxxxxxxxxx>]

Make yourself a script, include this:

   #!/bin/sh

   # first the load 5 and 15 min avg
   # multiply * 100 to avoid floats
   # it helps if mrtg "period" is a multiple of 5 mins
   uptime | sed -e 's/^.*average.*: \(.*\)$/\1/' -e 's/ //g' |
   awk -F, '{ printf("%.0f\n",$2*100); printf("%.0f\n",$3*100) }'
   # the uptime
   uptime | sed 's/.*\sup\s\(.*\),\s*.*user.*$/\1/'
   # my name
   uname -n

than for mrtg (in the mrtg.cfg file):

   Target[load]:           `THE_NAME_AND_PATH_OF_THE_SCRIPT_ABOVE`
   Options[load]:          integer,gauge
   Title[load]:            System load
   Xsize[load]:            600
   Ysize[load]:            200
   Ytics[load]:            10
   MaxBytes[load]:         3000
   PageTop[load]:          <H1>Load Average</H1>
   YLegend[load]:          Load Average
   ShortLegend[load]:      &nbsp;
   LegendO[load]:          5 minute average
   LegendI[load]:          15 minute stagger
