The Detailed Picture of Hardware Monitoring

Components from Three Different Applications
Hardware event monitoring involves components from three different applications:
• Event Monitoring System (EMS) provides the framework for event notification. EMS was originally
developed to support system monitoring, but the existing framework is used to manage hardware event
monitoring as well.
• Hardware event monitoring components include the event monitor, associated configuration files, and the
hardware monitoring request manager.
• Support Tools Manager provides the low-level error handling components that are also used for recording
and viewing system errors.
Hardware Monitoring Request Manager
Hardware event monitoring requests are created and managed using the Hardware Monitoring Request
Manager program. This tool allows you to easily create monitoring requests for all the hardware event
monitors running on your system. The Hardware Monitoring Request Manager uses all the notification
methods supported by Event Monitoring Service (EMS), giving you the ability to create a consistent
notification strategy for both system resources and hardware resources. The Hardware Monitoring Request
Manager is also used to enable or disable hardware monitoring.
Once created, all hardware event monitoring requests are handled by EMS, which uses the request settings to
determine how an event should be reported.
