I am interested in monitoring the performance of our WAEs using SNMP. I have had some success using the CISCO-WAN-OPTIMIZATION-MIB.
I have has some success in monitoring the sessions for each AO (but it is difficult to determine which AO is which)
.iso.org.dod.internet.private.enterprises.cisco.ciscoMgmt.ciscoWanOptimizationMIB.ciscoWanOptimizationMIBObjects.cwoAo.cwoAoStatsTable.cwoAoStatsEntry.cwoAoStatsActiveOptConns
A walk through the tree returns 7 stats (one for each AO I think).
However I am more interested in the TFO sessions, but the MIB appears not to return any values from the TFO objects:
.iso.org.dod.internet.private.enterprises.cisco.ciscoMgmt.ciscoWanOptimizationMIB.ciscoWanOptimizationMIBObjects.cwoTfo.cwoTfoStats.cwoTfoStatsActiveOptConn
Has anybody had any success with these variables in the MIB? Reporting session statistics to an SNMP management application would be very useful for trending and sizing WAAS deployments.
I am using WAAS version 4.4.5c and am not ready to upgrade to the latest release just yet.
Thanks in advance.

Hi Graham,
Could you try to poll the following OID:
.1.3.6.1.4.1.9.9.762.1.2.1.2
This should give you cwoTfoStatsActiveOptConn which is I believe what you are looking for.

Hi Nicolas,
Yes that is the OID that should report the number of sessions, but I am not getting a value returned.
However I do get a value from .1.3.6.1.4.1.9.9.762.1.3.1.1.11.4.99.105.102.115 which I believe is the CIFS AO current sessions. Could this me a MIB issue, or am I removing any dependencies on the MIB by using the OID directly?
Thanks for your help

Hi Graham,
Can you check the output of the following command on your device as it should give you the same value as the MIB:
show statistics connection optimized tfo
If you get values reported there and not on the MIB, it might be a bug which has been introduced in the latest software. Could you check if you have the same issue on WAAS devices running older code if you have any?

I could try some downgrading of code.
Have you used this before successfully?
Thank you for your help

Hi Graham,
This should work so I would definitively give it a try.
Maybe you could install the latest 4.1 on a box and see if you get proper values with that one or if you already get zero for this OID.
