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'.
Intended Audience
This guide is designed for use by engineers who are responsible for the configuration of Performance Monitor items and features in ClearSCADA. It can also be used by system administrators when investigating the cause of unexpected behavior relating to the Performance Monitor driver.
Document Scope
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 features for diagnostics that can be used by System Administrators and engineers when investigating unexpected system behavior (relating to the Performance Monitor driver).
Prerequisite Reading
This guide contains technical information that is intended for users that are sufficiently familiar with ClearSCADA configuration and operation. Before reading this driver guide, ensure that you are familiar with:
- ClearSCADA configuration practices, procedures, and the configuration of properties that are common to many database items. For more information, see the ClearSCADA Guide to Core Configuration, and the ClearSCADA Guide to Core Point Configuration.
- Driver structure, components, and configuration properties, pick actions, and status attributes that are common to many drivers. For more information, see the ClearSCADA Guide to Drivers.
- Simple driver composition, configuration order, and configuration properties and logging options that are common to many simple drivers. For more information, see the ClearSCADA Guide to Simple Drivers.
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. 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’).
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.)
