Performance Counters

Performance counters are an important part of the troubleshooting process. During the .NET framework installation process, a collection of performance counters is installed. These performance counters represent a goldmine of information when analyzing .NET application behavior. To view the performance counters, the Windows Performance Monitor can be used. Table 1-2 lists all the performance counter categories that are part of the .NET runtime.
