[mrtg] thresholds question

[Calvert, Neil]

Hi folks,

I was reading the MRTG docs today trying to get thresholding working. The
parameter ThreshProgI is defined as :

This defines a program to be run if ThreshMinI or ThreshMaxI is broken. (It
currently passes 3 arguments: the $router variable, the threshold value
broken, and the current parameter value. This can be changed as required.)

My question is what is the name of the three variables passed, so I can
reference them in a script? One of them is $ROUTER, but what are the other
two...? Or, when you define a script to be run, does MRTG run the script
like

'scriptname <routername> <threshold value broken> <current value>' 

so you would refer to each within the script as command line parameters $1,
$2, $3?

thanks

Neil
