David,

Try the command

snmpCollect ?

which will tell you what the default value of NumberConcurrentSnmp is.

Unless this was a new installation of NetView, your "original" value may not be the default.
The statement that you can increase it if you have network capacity and
NetView system capacity makes sense to me.
My guess is that to increase the number of concurrent requests snmpCollect
is going to have to maintain more state information or fork off new
processes. In each case this will need more CPU and memory and the question
is where does it start hitting limits on your box.
You should be able to see what happens by monitoring the trace file as you
increase the number.
I suggested the -S switch in my previous email. Did that give you
configuration information that shed some light?
Do you have verbose tracing on?  (-V and -T switches.)

Joe,

Thanks. The original config from our NV was 200 and I changed to 100 and 50
and back to 100. I read somewhere if the network capacity and NV box (CPU)
have no problem we can have it increased.

Rgds,
David

David,

I believe the default value of NumberConcurrentSnmp is 5, so 100 sounds
ambitious to me.

Did you increment it in steps and monitor the effect?

I would turn it back down, see if data is being collected, then increment
it in steps and check.

Try the -S switch also and look at the configuration information that it
writes to the trace file. This should tell you more about what is happening.
