Performance Counter

Advanced Network Monitor can poll Windows NT Performance counters from local or remote computers and notify the System Administrator when counter value changes by firing Alerts.

Windows obtains performance data from components in your computer. As a system component performs work on your system, it generates performance data. That data is described as a performance object and is typically named for the component generating the data. For example, the Processor object is a collection of performance data about processors on your system.

A range of performance objects are built into the operating system, typically corresponding to the major hardware components, such as memory, processors, and so on. Other programs might install their own performance objects. For example, services such as Windows Internet Name Service (WINS), or server programs such as Microsoft Exchange provide performance objects so you can monitor these objects with a help of ANM.

Each performance object provides counters that represent data on specific aspects of a system or service and instances for selecting the desired instance of the performance object. For example, the Pages/sec counter provided by the Memory object tracks the rate of memory paging.

To create or edit the Performance counter check open your Server properties window and select Windows performance counter from the Server type combo box.
Check the Local or Network computer and select the computer from your network (NOTE, you must have rights to access the registry on a remote computer).
Select the desired performance object from the Object combo box. The Instance and Counter combo boxes will update its content depending on the selected counter object. Select the desired instance and counter you want to monitor.
You can set the resulting server state depending on the counter value by setting the Server state, counter comparing operation and counter value boxes.

The message "Unable to connect to the specified machine." could be caused by the machine not being on, not running Windows NT/Windows 2000, not being connected to the network, or having the permissions set on the registry to not allow remote connections or remote performance monitoring by the user.

NOTE! You can use Performance counters check on Windows NT, 2000, XP and 2003.
