Larry,
This is most likely in the TEC ruleset and would need to be
handled there. Unfortunately my knowledge of the TEC rulesets
is somewhat limited, however, there are a few TECy people that
read this list and maybe they will chime in and give us a hand.
(hint hint;-)

Paul,
Thanks for looking into this.. My situation is this..
I have inherited this environment.. Netview poll
settings is as below but in TEC these interface down
events are held for 10 minutes.. If no Up is received
from same hostname, then an down alert goes out to
team.. Now the issue is why is this 10 minutes hold in
TEC. Can't i lower this to lesser value.. Is there any
issues or false events generated if i lower 10 minute
hold since we have about 17,000 interfaces to poll..
What is the industry standard in polling the nodes? My
customers are saying "It's really NOT good to know
that the server is down ONLY after about (10+3)13
minutes"..
Again many thanks as usual..

Larry,
This is actually pretty simple;-)
With the polling set as you have it:
netmon will poll each device once every three
minutes, it will
wait 5 seconds for a reply and will try a total of 4
times per
device if there are any failures.
For the question about how netmon polls(sequential
vs simultaneous),
the answer is yes. Netmon has a fixed(but
configurable) number of
threads available for polling, for each ICMP and
SNMP. So netmon will
poll X number of devices at the same time and then
all devices as it gets
around to them.
To see the list of devices being polled you can run:
netmon -a 12 (to see what netmon is polling via
ICMP)
netmon -a 16 (to see what netmon is polling via
SNMP)
This information will be stored in the
/usr/OV/log/netmon.trace file.
That being said, you might find looking through
17,000 IP addresses
a bit tedious;-)

Gentlemen,
I have gone through tons of info in list on this
topic. But i just need a simple answer for my
configuration. I have set timeout=5 retries=3
polling=3m. Now can some one tell how the polling
works in this case? how does netmon poll fo rup and
down's?
My second question is, I have about 17,000
interfaces
to be polled in my DB. Does the polling to all
these
interfaces happens sequentially or simulataneously?
How can i check if all my nodes are being polled?
Is
there a way to see all of my nodes are polled?
I'm really exhausted looking into this.
Please could someone help me?
Many Thanks as usual.
Larry
