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

Hewlett-Packard's application for creating and managing

 

 

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.

 

 

 

 

Multiple-view

As of the June 2000 release (IPR 0006), certain monitors will

 

 

allow event reporting to be tailored for different targets

 

 

(clients). This “multiple-view” (“Predictive-enabled”) feature

 

 

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.
