The Performance Counters group of the default project properties allows you to configure the list of monitored counters and usage options for new TestComplete projects. For more information about managing performance counters with TestComplete, see Adding Performance Counters.
To view or change the default options, select Tools | Default Project Properties from the main menu of TestComplete and then choose Performance Counters from the tree displayed on the left side of the ensuing Default Project Properties dialog.
The counters specified in this dialog will be assigned to appropriate project settings of the Performance Counters group when a new project is created. You can then modify them on the Properties page of your project editor (see Project Properties - Performance Counters Options).
