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.
