5242.0. "SNMP statistics vs counters" by BIGUN::MAYNE (`AXP!': Bill the Cat) Wed Jun 23 1993 06:40

How are statistics calculated? Does MCC do something like:

1. Get counters.
2. Wait 60 seconds.
3. Get more counters.
4. Display (counters2 - counters1)/60.

or does the SNMP entity do the calculations and send them to MCC?

A customer has some X terminals that return likely looking numbers for
Ethernet counters, but zero for all of the Ethernet statistics. We'd like to
figure out if SNMP on the X terminals isn't fully implemented (even though the
vendor says it is), or if MCC is missing something.

    Yes. That's exactly how the PA FM synthesizes statistics. For SNMP it
    derives them from MIBII variables.  If the Xterminal in question doesn't
    completely implement MIB II, then the PA FM can't calculate the statistics.

    See if the X terminals in question will return counters for the MIB II
    objects.  	E.g.  
    		MCC> SHOW SNMP Xterm1 interface * all count
