New Troubleshooting Features

Four new troubleshooting options are available to Performance Monitor users:

• You can configure Performance Monitor to log an error to the Event Viewer application event log when it fails to retrieve data or gets unreadable or uninterpretable data. This is recommended for frequent users of Performance Monitor.

• You can configure the Performance Library to log its errors to the Event Viewer application event log and you can control the level of detail that it logs. Performance Library functions are the data source for Performance Monitor.

• You can also determine the extent to which Performance Library tests the data buffers of extensible counters. This is recommended for users and developers of extensible counters.

• With Windows NT 4.0, the Performance Library now times the Open procedure call of extensible counters and writes an error to the application event log when a time threshold is exceeded. This helps you identify counter problems that might otherwise prevent remote users from logging on to the computer.
