Before you begin
When you enable instrumentation, you enable all configured diagnostic monitors in the diagnostic module. When you disable instrumentation, you disable all configured diagnostic monitors in the diagnostic module.
Note: Diagnostic monitors can also be individually enabled and disabled. However, Enable for the diagnostic module must be selected, as described in this step, for any individually enabled monitor to be active. If Enable for the module is deselected, all monitors are disabled, no matter what their individual settings are.
