Performance Logs & Alerts (pla) Service Defaults in Windows 7

Performance Logs and Alerts Collects performance data from local or remote computers based on preconfigured schedule parameters, then writes the data to a log or triggers an alert. If this service is stopped, performance information will not be collected. If this service is disabled, any services that explicitly depend on it will fail to start.

Default Behavior

Performance Logs & Alerts is a Win32 service. In Windows 7 it won't be started if the user doesn't start it. When the Performance Logs & Alerts service is started, it is running as NT AUTHORITY\LocalService in a shared process of svchost.exe. Other system components, such as drivers and services, may run in the same process. If Performance Logs & Alerts fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the pla service is not running because of the error.

Dependencies

Performance Logs & Alerts is unable to start, if the Remote Procedure Call (RPC) service is stopped or disabled.

Restore Default Startup Configuration for Performance Logs & Alerts

Before you begin doing this, make sure that all the services on which Performance Logs & Alerts depends are configured by default and function properly. See the list of dependencies above.

1. Run the Command Prompt as an administrator.

2. Copy the command below, paste it into the command window and press ENTER:

sc config pla start= demand

3. Close the command window and restart the computer.

The pla service is using the pla.dll file that is located in the %WinDir%\system32 folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 7 installation media.
