Windows 2003 Server NLB monitoring

[Tony]

We have a web app balanced across 2 servers. Is there a way to
monitor the load? I would like to see which server in the NLB cluster
a user is connected to. TIA

It all depends on the NLB mode you used to set it up. NLB doesn't
necessarily mean that once the user establishes the connection, they will be
tied to that server all along. They can keep switching during the session.
Know what I'm getting at?

You can use perfmon to monitor the load on the servers.

Tony -

you can also use netstat.exe to see all TCP connections being serviced by a
particular server at a given point in time... is your cluster configured in
"single" affinity??? if so, then a given client should always map to the
same NLB host so long as the NLB cluster membership does not change - if it
does, the client may begin being serviced by another node...

as jack mentioned, if you want to just generally monitor the load on a given
NLB node, then use perfmon to monitor the number of active TCP connections,
or connections per second, or some other relevant load indicators...

hope this helps...

cheers, sean
