Online Diagnostics

Online Diagnostics contains the following utilities:

• Event Monitoring Service (EMS) Hardware Monitors – EMS Hardware Monitors

proactively and continuously monitor the status of hardware components and

automatically notify you when a component is failing or has failed.

• Support Tools Manager (STM) – STM enables you to instantly check the status

and property information of hardware components and perform various tests on

hardware components.

This section describes EMS Hardware Monitors and STM.

EMS Hardware Monitors

EMS Hardware Monitors are software utilities that enable hardware monitoring on a

system that is running the HP-UX operating system software. Hardware monitoring uses

special processes (daemons) to continuously monitor hardware components for the

occurrence of any unusual activity, called an event. If an event is detected, a message that

includes information about the event, the cause, and corrective action is immediately sent

using the notification method defined for the hardware monitor.

The following lists some of the hardware components for which EMS Hardware

Monitors are available:

• Disk arrays

• Disk products
