Out-of-the-Box Counters

ATL Server provides a number of common counters out of the box. These counters are designed to give you an example of items that are very useful to monitor with a system such as Perfmon.

The ATL Server development team tried to provide many of the common examples of counters they thought Web application developers might find useful, but it s always possible to add your own custom counters, as you ll see in the next section. Here s a list of the counters provided:

• Active Threads

• Average Response Time

• Current Queued Requests

• Maximum Queued Requests

• Server Failed Requests

• Server Requests per Second

• Server Total Requests

Note  

If you use the same ISAPI DLL for multiple applications (i.e., the same filename and the same directory), then your Perfmon statistics will be a combination of statistics for both applications. To avoid this, simply use a differently named ISAPI DLL or a different directory for the ISAPI DLL for each application you want to monitor.
