Performance Counters Reference
Performance counters measure quantities of information or data, according to the number, size, duration, and rate of data being requested or received. You should not expect to get a list of details from a counter, such as a list of error messages. Instead, use performance counters to get quantities, such as the number of error message since startup or the rate at which error messages are being generated.
You can access counter data through the System Monitor (formerly known as Performance Monitor), an MMC snap-in, or programmatically by using Windows Management Instrumentation (WMI).
The following tables of counters are included in this reference:
- Web Service Counters
- ASP System Monitor Counters
- Web Service Cache Counters
- IIS Global Counters
- FTP Service Counters
The tables in this reference contain the following information about each counter:
- The name of the counter
- A description of the data the counter maintains
- The name of the component that tracks the counter
- The granularities of the data the counter provides (for example, total and site)
- Whether the counter calculates a value
- The data typeof the counter (for example, 64- or 32-bit)
- Whether the counter is new to IIS 6.0
Web Service Counters
Web Service Counters are available in both IIS 5.0 isolation mode and worker process isolation mode.
