RE: (ASCEND) SNMP oddities
Hello Dave, I'm the product manager for NavisAccess. My group also
controls SNMP MIBs in the Ascend Access boxes.
I'm not sure there is any real difference between eventTotalCalls &
eventTotalSessions. They both increment when I make bad calls into a TNT.
As for eventTotalCallsAnswered & eventTotalCallsOriginated they just show
direction and should add up to eventTotalCalls. These OIDs show all calls
regardless of whether they are sessions or not.
The best way I know of to pick out sessions vs. bad calls is to use RADIUS
accounting data. Data is created for each call and should be accumulated by
your radius server. Roughly the same information can be retrieved from the
eventTable but it will only store a few thousand entries and some of the
entries are not part of what you want to see. So you would have to sort
through the data to find what you want.
As for retrieving the total number of active session try the call MIB
(attached). The call MIB is the best place to get the number of currently
active sessions sorted by type. The bad news is that the call MIB is
partially broken in some 2.1.x versions of software.
Please let me know if you have any more questions

Subject: (ASCEND) SNMP oddities
Hello,
in looking into some of the Ascend-enterprise MIB's, it appears that some of
the values are completely redundant, and do not really measure what they
purport to measure. For example:
OID: 1.3.6.1.4.1.529.10.7
OID full path:
iso(1).org(3).dod(6).internet(1).private(4).enterprises(1).ascend(529).event
Group(10).eventTotalCalls(7)
[henceforth eTC in my shorthand]
Is the same thing on my TNT, as its neighbors 1.3.6.1.4.1.529.10.8 and
.10.9, or in English:
eventTotalSessions and eventTotalCallsAnswered. [eTS & eTCA]
My hope was that the eTC would show all calls, regardless of whether a LAN
session was established. My goal would be to find times when we were
receiving hundreds of calls, but no user logins were successful. We have
many problems with the 2.1.0 code, not the least of which are reports of
multiple connect attempts before a successful login. I know, I know, 2.1.9
is released... I'm just nervous about resetting my TNT again, since it took
a full day before it would answer any non-ISDN calls (it just retrained
endlessly) the last time I upgraded.
Am I mistaken that Total Calls should be all calls, and not just those for
which a session was created?
Another rant: why is there no way to retrieve a statistic for total users
other than to use the last user index value to? Total sessions != total
users != total channels in use
Don't get me wrong, I love the box -- I just love to hate it, too. =P
Thanks,
Dave Langlands
