About This Manual

This guide is intended for use by system administrators and others involved in managing HP-UX system hardware resources. It describes the installation and use of (EMS) Hardware Monitors—an important tool in managing the operation and health of system hardware resources.

The book is organized as follows:

•Chapter 1, “Introduction,” provides a foundation for understanding what the hardware monitors are and how they work. This material will help you use the hardware event monitors efﬁciently.

•Chapter 2, “Installing and Using Monitors,” describes the procedures for creating and managing monitoring requests.

•Chapter 3, “Detailed Description,” gives a detailed picture of the components involved in hardware monitoring, their interaction, and the ﬁles involved.

•Chapter 4, “Using the Peripheral Status Monitor,”covers the Peripheral Status Monitor (PSM), which serves as the interface between the event-driven hardware event monitors and MC/ServiceGuard.

•Chapter 5, “Hardware Monitor Conﬁguration Files,” describes how to control the operation of hardware monitors by modifying the conﬁguration ﬁles.

•Chapter 6, “Special Procedures,” describes monitor-speciﬁc tasks.

NOTE	The information previously contained in the chapter titled “Monitor Data Sheets,” has been
	moved to the Web at http://docs.hp.com/hpux/onlinedocs/diag/ems/emd_summ.htm.
	An HP-UX man page is available for each monitor. To access the man page, type:
	man monitorname
	where monitorname is the executable ﬁle listed in the data sheet.
