Iis – ny open source web server monitor for IIS

I think Nagios is the best way to Monitor all stuff on a server/s :)

Nagios

With nagios you can monitor your server/s with plugins ..

you use ssh smtp or web based solutions and if no plugin is aviable write your own one

Nagios gives you a very great web based monitoring tool:

With Nagios you can:

• Monitor your entire IT infrastructure
• Spot problems before they occur
• Know immediately when problems arise
• Share availability data with stakeholders
  
• Detect security breaches
• Plan and budget for IT upgrades
• Reduce downtime and business losses

And many many more.. At the moment are more than 2000 plugins aviable Like Check_disk - check_proc (process) check_smtp ...

plugins aviable

I like it its open source greez bull

What I want is another (possibly more than 1) measure that's between these two measurements. How would I take such measurements?

If you have access to the developers that created this application, get them to write a small instrumentation package (non-blocking!) that allows you to pull this counter out of the application directly.

If you can't you will need to start debugging the application itself to determine how long and where it's spending time in execution.

Since this is a windows machine, you can start with process monitor to get a high level idea of what happens during each request. Then you can move onto more robust debugging tools like windbg logger.exe.
