[mrtg] Change in Thresh handler

[bwoodcoc]

Greetings,

I have recently upgraded from 2.7.5 to 2.9.17 and have noticed a change in 
the handling of thresholds (I think). In the old version script execution 
was every breach of the threshold (potentially every 5 minutes) and then on 
the clear. In the newer version it seems that execution is on the initial 
breach and then on the clear with NO execution for contiguous 5 minute 
occurrences between the two.

Reading the docs it probably "functions as designed" with 2.9.17 given 
folks are generally using it for notification (email, page). However I 
found the old technique useful for error analysis and alarm display. This 
is because I was capable of logging every incident of threshold violation. 
I was then able to roll up totals and averages of each error type for 
targets in a topN fashion to highlight trouble spots. This now does not 
seem possible at least using this technique. Also every alarm was written 
to an additional directory for an web alarm manager display and therefore 
always showed me the current values on my net.

Are my assumptions of threshold operation for 2.9.17 correct and is there 
any way (an option) to convert back to the previous? I checked the docs but 
did not see any technique as yet.

cheers,
brad...
