[mrtg] Re: External ping program

[Stieers, Ken]

The cfg file doesn't change, the output of your program has to be as follows
(taken from the config.html file that is part of the DOCUMENTATION):
if you want to monitor something which does not provide data via snmp you
can use some external program to do the data gathering. 

The external command must return 4 lines of output: 

Line 1
current state of the first variable, normally 'incoming bytes count' 

Line 2
current state of the second variable, normally 'outgoing bytes count' 

Line 3
string (in any human readable format), telling the uptime of the target. 

Line 4
string, telling the name of the target. 

Depending on the type of data your script returns you might want to use the
'gauge' or 'absolute' arguments for the Options keyword. 

Example: 


 Target[ezwf]: `/usr/local/bin/df2mrtg /dev/dsk/c0t2d0s0`

Note the use of the backticks (`), not apostrophes (') around the command.
