[THIN] Re: Trend Analysis / Server performance issue

Start with:  Memory, HARD Pages/sec, CPU.  
If you set up perfmon on another machine it will cause very little overhead
to your servers.
Once you understand if it is paging or CPU there are more detailed counters
to look at (my money is on the paging).  If your issue is network traffic
you are better off with another tool.

Subject: [THIN] Re: Trend Analysis / Server performance issue

Hi

Thanks for your replies.  I will do some investigation in regards to some of

the products you have mentioned.  Id like to quickly get up to speed on the 
state of the servers by using perfmon for now then look into third party 
products.

Can anyone recommend what counters I should use to do this?  Memory usage / 
Page File and CPU appear to be the key indicators as these are the settings 
resource manager has alerted me on.

Ive never used Performance Monitor before.  If I ran this on all servers for

2 weeks, how much of a performance hit is it going to be?.  My servers are 
stressing as it is.  I don't want to bring them all down my monitoring too 
much information.

Any help appreciated

Angela
