Publishing Performance Counters

Hi all,

I am currently working on a server application
- running on a 64 bit intel machine
- OS 'Windows 2003 server".

The server application is written in C++ and I have to publish
performance data from this app like uptime, no of clients etc. Is
there any library available that I can use to publish "Performance
counters". If I decide to use WMI I am afraid I might need to modify
the server to support ATL-COM. Is there any other method to do it.

Any help,link,sample is appreciated.

Thanks,
SB
