RE: [NV-L] NV 7.1.4 AIX--advice on ksh nmdemandpollscript--coprocessing

["Van Order, Drew \(US - Hermitage\)" <dvanorder@deloitte.com>]

Thanks for this. netmon -a was a good idea, but don't think it's necessarily accurate. For example, the nodes produced in the list titled snmpList don't guarantee they are queried. I also need just nodes, don't want interfaces. Option 8 looks perfect for getting the SNMP queried nodes, but nothing gets just the pinged nodes, at least not that I can see.

 

I have something working for quicktest--it's much easier on CPU than nmdemandpoll. That too can hang, and when it does, it doesn't seem to have a timeout to save itself...or does it?

 

Thanks--Drew

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

Subject	[NV-L] NV 7.1.4 AIX--advice on ksh nmdemandpoll script--coprocessing

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. --Drew
