This driver is a simple driver. It provides additional functionality to enable ClearSCADA to interface with specific supported devices using a particular protocol. To interact successfully with such devices, you need to:
- Install and run the driver
- Ensure that the driver is licensed
- Configure the required database items and settings on the driver
- Ensure that the database items (and any database items on which they depend) have valid, saved, configuration and are 'In Service'.
The Performance Monitor driver (sometimes referred to as NTMon) uses Performance Monitor scanners in conjunction with Performance Monitor points to monitor various aspects of performance on a ClearSCADA system.
Each Performance Monitor scanner defines which computer is scanned and how often the scans occur.
Each Performance Monitor point defines which particular aspect of system performance (for example, CPU Usage) is monitored.
A wide variety of performance attributes can be monitored. The attributes that you can monitor vary, depending on the version of Windows® that is running on each PC, and the system setup.
The Performance Monitor documentation explains how to configure Performance Monitor-specific features and items within the ClearSCADA database (see Configure Performance Monitor Devices in ClearSCADA).
It also explains the driver-specific aspects that can be used by System Administrators and engineers when investigating unexpected system behavior (relating to the Performance Monitor driver). For more information on the statistics and diagnostics that are available, see Performance Monitor Specific Status Display Attributes.
NOTE: There are no driver-specific pick actions for database items on this particular driver. However, users with the required privileges can add custom pick actions to a database item by using the User Methods tab on the relevant configuration Form (see Using the User Methods Tab to Define Custom Actions in the ClearSCADA Guide to Core Configuration). See a system administrator for the documentation associated with such custom actions (also known as ‘methods’).
NOTE: To access the driver log file options for the Performance Monitor driver, you select the NTMon driver entry in the Modules section of the ClearSCADA Server Status Tool. (For more information on driver log file options, see Define the Driver Logging Settings in the ClearSCADA Guide to Server Administration.)
