[mrtg] Delayed Threshold Actions

[dan.lowry at attbi.com]

Here's a batch file that seems to work for Windows 2k.
It looks at inbound link utilization for 20 minutes, and if it's over
threshold for 20 minutes, an email gets sent.
Thanks to the group at windowsshellscripting.com  for providing this usefull
script !
It has provisions to get past an issue with threshprogok where
if you enable threshdir which is needed for threshprogok to kick off,
then you no longer kick off threshprogx every 5 minutes (Only
every hour)
This batch file when run will create  a timestamp, and if the last time the 
file was updated was > 7 minutes ago, will set the count variable back to 1.
that way if you have a couple of threshold breaches, and then it goes back to 
normal, you won't leave stale values in the temp file and get a premature email 
next time. 

No guarantee, but it seems to work for me. It will also have an issue at the 
end of the year boundry , if anyone can fix that it would be appreciated.

Otherwise, Here you go, it works for me on windows 2k server.

Good luck !
