Windows 2003 Server capacity planning and utilisation monitoring

Hi All

We have several different types of applications running on our Windows 2003 SP2 Servers - IIS, SQL 2005 etc.

So far, we haven't really been looking into capacity planning or performance monitoring to find out if the servers are over-utilised. Generally, if someone happens we fix it :)

I guess Perfmon is the best tool to run for this? Does anyone know any other ones?

Also, as regards Perfmon, I remember there used to be an MS document for what the "safe" values were (e.g. recommended max CPU usage, commited bytes etc), but I can't find it for the life of me! Does anyone know?

Also, are there any counters specific to IIS and SQL we should be monitoring for?

Many thanks in advance.

This is a good starting article for using perfmon.

As for monitoring IIS, you could look at processor time for specific services eg. Inetinfo

There are plenty of other monitoring products that can be purchased, Quest have quite a few.

I agree that Perfon is enough. But it works only locally, so maybe it is a better idea to use some central monitoring software? I would recommend setting up Nagios in your network it is very powerful monitoring tools and very flexible. Then you will be able to check all of your servers in a network.
