Thread-topic: [nv-l] Polling Question
CPUs on the server are no where near pegged...In fact, they are running at about 3% and peaking at about 6%.
Is the Windows platform of Netview multithreaded?
I also took a sniffer capture of some of the traffic.  Netview is polling data such as interface errors, interface octets, etc.  Is there a way to control which devices are polled for this data?

with 900 nodes in a local hosts file it is likely you are experiencing high CPU? You have a dual CPU box, do you have tools that will show how the CPU usage is on each? If you are total at 50%, could that mean that netmon is pegged one of the CPUs? In the past I did this on a NetView server on a 4-way. When I switched from a large hosts file to a caching DNS configuration my netmon CPU usage went from 100% (of a single CPU) down to 6%.

I suggest you build a DNS on your Windows machine or one on the same subnet and get rid of your hosts file. Having DNS co-exist on your NetView server is the best.
