Chapter 20. Using the SP System Monitor

The SP System Monitor allows authorized operators and administrators to operate and monitor the system hardware. It allows authorized users to control and monitor the status of the frames, nodes, and switches of the SP system. It is a client-server application. The server, the hardmon daemon, executes only on the SP control workstation and controls the SP supervisor subsystem through the device special files for the RS-232 connections to each frame supervisor. You can use the SP Hardware Perspective graphical user interface or you can use the line commands to perform the tasks. For information on the SP Perspectives GUI, see Chapter 19, Using SP Perspectives. If you are familiar with the pre-PSSP 3.1 system monitor GUI, you might be interested in Performing common administration tasks with SP Perspectives that were previously performed using the System Monitor GUI.

The SP System Monitor is made up of the following parts:

Hardware Monitor

A set of commands and a daemon used to monitor and control the SP hardware platform.

Command interface

The spmon, hmadm, hmdceobj, hmmon, hmcmds, s1term, and nodecond commands with their flags and parameters, provide a way to monitor and control the system at an individual system partition level or at a global (all system partitions) level. These can be used from an ASCII terminal, such as those used on a dial-up line, from scripts, or from another terminal.

Logging daemon

The splogd logging daemon logs SP hardware state changes, reports SP hardware errors, and provides a state change alert.

This chapter provides conceptual information and procedures for configuring and using the SP System Monitor. Figure 36 presents a functional overview of the SP System Monitor.
