Howdy,
You could make the first step of this run a little faster by using the
nvUtil command instead of nvdbformat. The 'while read hostname' line below
could be changed to:
for hostname in `/usr/OV/bin/nvUtil e "((isNode=TRUE) &&
(isSNMPSupported=TRUE))"`
This should return an unsorted list of device (not interface) selection
names for isSNMPSupported=TRUE object very quickly.

Folks,
I have something working that does the job and appears very accurate.
Thought I'd share it after learning the netmon commands did not meet our
requirements, and quicktest/nmdemandpoll were performance killers. The
output tells you which SNMP capable devices are being monitored with ping,
and which ones are being SNMP queried for status. Great for auditing.
It's 2 steps--
1. Use nvdbformat to spit out a list of devices where isSNMPSupported=TRUE.
You must get the Selection Name, whatever it may be. If you don't; the
ovtopodump command used below will not return the SNMP STATUS POLL field:
SELECTRULE:isSNMPSupported=TRUE
SELECTFIELD:1:Selection Name
SELECTFIELD:2:SNMP ipAddress
GROUPBY:1:Selection Name
SORTBY:1:Selection Name
OUTPUT:${1}
2. Feed the output of this to a script that does the following:
while read hostname
do
if [[ `ovtopodump -rl $hostname |grep -c "SNMP STATUS POLL: MAXIMUM TIME"`
-ge 1 ]]
then
echo "$hostname is monitored using ping" >> $FILE
else
echo "$hostname is monitored using SNMP query" >> $FILE
fi
done

I think one of the netmon action commands (netmon -a xx ) might produce
that list in netmon.trace. Check the man page for netmon.

Hi all,
Our DNOC needs a report that shows what IP addresses are managed via SNMP
query versus ping. I searched the archives and it appears one can't get
this report using nvdbformat--isSNMPSupported is not an accurate indicator.
So, I'm getting the list of IP's that match isSNMPSupported=TRUE from
nvdbformat, then feeding the list into `ndmdemandpoll $hostname |grep "Get
SNMP status"`. This will do the job, but we all know nmdemandpoll kills CPU
if it takes any time at all to run. I have 1500 addresses to cycle through.
So, I figure I can kill nmdemandpoll if it's going to take longer than 15
seconds to finish, log the IP address that needed to be killed, then go
back to the loop. No problem, except I'm a novice ksh scripter, and having
trouble with co-processes (required to watch the nmdemandpoll PID because
nothing will occur until nmdemandpoll finishes, right?). If someone can
help me with the logic, I'll post the whole smash for everyone to use when
it's finished.
This works fine, just takes forever, and sends uptime values skyward. It
sets off NetIQ alerts for CPU utilization.
# Read in IP address list from NVout.report
# nv_getSNMPquerystatus.sh < NVout.report
while read ipAddress
do
nmdemandpoll $ipAddress | grep "Get SNMP status"
if [[ $? -eq 0 ]]
then
echo "$ipAddress is currently monitored using SNMP query"
else
echo "$ipAddress is currently NOT monitored using SNMP query"
fi
done
Many thanks in advance to anyone with advice on how to finish this one off.
