Checkmk local script:

Read out data from an rrd file and show the values e.g. bandwith up- and downstream:

# /usr/lib/check_mk_agent/local

#!/bin/bash
# set -x

workdir='/opt/iperfmon'
#get data for altoo_office
downstream=$(/usr/bin/rrdtool lastupdate $workdir/iperfmon.rrd |tail -1|awk '{ print $2}')
upstream=$(/usr/bin/rrdtool lastupdate $workdir/iperfmon.rrd |tail -1|awk '{ print $3}')

echo "0 Iperfmon downstream=$downstream|upstream=$upstream Iperf up- and downstream: $upstream | $downstream (MBit/s)"

#echo "0 My service myvalue=73 My output text which may contain spaces"
