[mrtg] Re: Setting Alerts by configuring Threshold Checking

[Vaibhav Bawa]

Hi,

I'm able to invoke a script when the link goes below a specified threshold,
via ThreshProgI, but am unable to do so when the link resumes its normal
operation, via ThreshProgOkI. The problem is mrtg doesn't give any errors
while initialising, but it just won't execute the script when the link
utilization exceeds 20%, i.e. the ThreshMinI I've specified.

Have you ever used ThreshProgOkI? I'm attaching a sample cfg file below

Its probably going to be as simple as the full path to the
ls program. On Redhat Linux `/bin/ls`


-- Cut due to overquoting check.... --

>ThreshProgI[172.17.72.2_2]: `ls`
