NAME

       mrtg-ping-probe - ping probe module for Multi Router Traffic Grapher

DESCRIPTION

       mrtg-ping-probe  is  a  ping  probe  module  for MRTG 2.x.  It is used to monitor the round trip time and
       packet loss to networked devices.  MRTG uses the output of mrtg-ping-probe to generate graphs visualizing
       minimum and maximum round trip times or packet loss.

       mrtg-ping-probe is not run directly, but is called by MRTG as a helper when it needs  to  determine  ping
       time to a host.

       Act responsibly: do not use mrtg-ping-probe to ping devices without the owner's permission.  Just imagine
       if  10,000 people decided to ping your hosts!  mrtg-ping-probe is meant to be used within your network to
       get round trip time performance figures for your network.

OPTIONS

       To use mrtg-ping-probe you need to configure MRTG to call it from within the definition of a target host.
       This is done in the MRTG config file, which is usually /etc/mrtg.conf.

       Here's an example snippet: change the target name and IP address to suit your needs.

       Target[your.target.ping]: `/usr/bin/mrtg-ping-probe 123.456.789.123`
       SetEnv[your.target.ping]: MRTG_INT_IP="123.456.789.123" MRTG_INT_DESCR="ping"
       MaxBytes[your.target.ping]: 100
       AbsMax[your.target.ping]: 200
       Options[your.target.ping]: gauge, growright
       YLegend[your.target.ping]: ping time (ms)
       ShortLegend[your.target.ping]: ms
       Legend1[your.target.ping]: Maximum Round Trip Time in ms
       Legend2[your.target.ping]: Minimum Round Trip Time in ms
       Legend3[your.target.ping]: Maximal 5 Minute Maximum Round Trip Time in ms
       Legend4[your.target.ping]: Maximal 5 Minute Minimum Round Trip Time in ms
       LegendI[your.target.ping]:  Max:
       LegendO[your.target.ping]:  Min:

       Pay close attention to the backticks in the first line which tell MRTG to execute the nominated  external
       program.  Note  also that you need to use the "gauge" option, since the results of subsequent ping probes
       are independant values and not an incrementing counter.
