Eric,
Running a "netmon -a 12" will dump the ping status list into the netmon.trace. This should show you the next time this device will be polled, it will show you
something like this:

---------- pingList [0x82ba2b0] ----------
** 94 elements on the IF list **
 3: 10.22.33.44 (test123) list = 0x82ba2b0

That shows 3 seconds until that interface will be polled.

Also, the ICMP vs SNMP, NetView will sometimes make that decision for you.
If the device has a unnumbered serial interface it should be being polled via
SNMP. You can check for sure by running an "ovtopodump <selection name>"
then looking for SNMP STATUS POLL and if it is MAXIMUM TIME, then the
device is being polled via ICMP. You can also look to see when the last poll
was by looking at the LAST SUCCESSFUL POLL in the interfaces portion of
the ovotpodump command.

Other then that, you would have to trace netmon to see what it is doing.

Paul,
Thanks for your reply.  I'm not doing any snmp status polling, and the
status of the object is Normal/Up.

Sounds like it might be being polled via SNMP instead of ICMP. Also, you
can check the object properties to make sure the object is not in
Critical status and just incorrectly reprensented on the map....

NV 7.1.4 on AIX 5.2

What would cause the map node to stay green when ping fails?

Background:
On backup netview box node goes down.  On primary box node is up.  When


I do a manual ping from the primary box the ping fails, but the node stays green. IP address is the same on both boxes.
Thank you,
Eric
