Hardware Monitoring Overview
Table | Hardware Monitoring Terms | |
|
|
|
| Term | Definition |
|
|
|
| Hardware event | A monitor daemon that gathers information on the |
| monitor | operational status of hardware resources. Each monitor is |
|
| responsible for watching a specific group or type of hardware |
|
| resources. For example, the tape monitor handles all tape |
|
| devices on the system. The monitor may use polling or |
|
| asynchronous event detection for tracking events. |
|
| Unlike a status monitor, an event monitor does not |
|
| “remember” the occurrence of an event. It simply detects and |
|
| reports the event. An event can be converted into a more |
|
| permanent status condition using the Peripheral Status |
|
| Monitor. |
|
|
|
| Hardware resource | A hardware device used in system operation. Resources |
|
| supported by hardware monitoring include mass storage |
|
| devices such as disks and tapes, connectivity devices such as |
|
| hubs and multiplexors, and device adapters. |
|
|
|
| MC/ServiceGuard | |
|
| high availability clusters of HP 9000 Series 800 computers. A |
|
| high availability computer system allows application |
|
| services to continue in spite of a hardware or software |
|
| failure. Hardware monitoring integrates with |
|
| MC/ServiceGuard to ensure that hardware problems are |
|
| detected and reported immediately, allowing |
|
| MC/ServiceGuard to take the necessary action to maintain |
|
| system availability. MC/ServiceGuard is available at |
|
| additional cost |
|
|
|
| Monitoring request | A group of settings that define how events for a specific |
|
| monitor are handled by EMS. A monitoring request identifies |
|
| the severity levels of interest and the type of notification |
|
| method to use when an event occurs. A monitoring request is |
|
| applied to each hardware device (or instance) supported by |
|
| the monitor. |
|
| Monitoring requests are created for hardware events using |
|
| the Hardware Monitoring Request Manager. Monitoring |
|
| requests are created for changes in hardware status using |
|
| the EMS GUI. |
|
|
|
| As of the June 2000 release (IPR 0006), certain monitors will | |
|
| allow event reporting to be tailored for different targets |
|
| (clients). This |
|
| will be added to all hardware monitors in future releases. |
|
| Previously, hardware monitors generated events the same |
|
| way for all targets. The problem is that different targets, |
|
| such as Predictive Support, may have different requirements |
|
| for events. |
