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 
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
