[mrtg] Re: Monitor Frame Relay availabilty & accuracy

[Paul C. Williamson]

Are you trying the math on those OIDs in the target?

Something like:

Target[blah]: OID1&OID2 * 100 / OID3&OID4

?  That won't work.  You almost need to write an 
external script any interface it back in to MRTG.

Hi Paul,

Minimum is 11.3 - 12.0.
I have no problem monitoring the usage and link performance, CPU and 
Memory usage. I can't monitor the accuracy and availability though.
When I double-checked with GetIf program, all variables in the 
formulas below return no value.

Thanks
Seiya Lin

What version of IOS are you running?
I can monitor my F/R interfaces with no problems at all.

Hi,

does anyone here know how to monitor network availability and 
accuracy for Frame Relay for Cisco routers?

Below is the formula I got from Cisco Press book: Performance & Fault 
Management
Accuracy: ifInErrors *100 / (ifinUCastPkts + ifInNUCastPkts)
Availability: MTBF / (MTBF + MTTF)

For Accuracy, the OID is only for serial interface. It doesn't return 
any value for my frame relay ports.

Thanks for your help
Seiya Lin
