Can you please provide me some examples or info urls for setting the mrtg to
notify me when the traffic is below expected value in a given period of
time. At least is it possible to do it with mrtg.
Thanks in advance
ThreshMinI (PER TARGET)
This is the minimum acceptable value for the Input (first) parameter. If
the parameter falls below this value, the program specified in
ThreshProgI will be run. If the value ends in '%' then the threshold is
defined relative to MaxBytes.
MRTG has a threshold checking feature which can be activated using the
Thresh* parameters in your config file. See the reference.html document that
came in the docs section when you downloaded mrtg.
Basically, if the Input [or Output] value falls below the threshold
specified by the ThreshMinI [or ThreshMinO] parameter, then MRTG calls the
script defined in the ThreshProgI [or ThreshProgO] parameter, and passes it
3 arguments - the $router variable, the threshold value and the curent
You just need to customise your script to notify you once it is called by

Hello, and thank you in advance for any response.
I am trying to find the default thresholds built in to Cisco router and
switch IOS for snmp alarms to be sent to an HP OpenView collection station,
as well as log files. I receive events for late collisions, excessive
collisions, CRC errors, network critical errors, etc., but I don't know at
what point (the formulas used) the router determines that these events are
in fact errors.
I need to know this information in order to determine what additional
threshold polling parameters need to be applied for intelligent network
