Product Overview

Event Monitoring Service (EMS) is a framework for monitoring system resources which

includes configuring, checking resource status, and sending notifications when configured

conditions are fulfiled.

EMS contains the following components:

• EMS Framework - The EMS framework provides discovery, configuration, and

notification for EMS monitors. Depending on the monitor, EMS may actively poll or it may

wait for event messages. It compares the return value with the threshold configured in

the request. If it matches, the framework sends notification to the source specified,

through a required protocol.

• EMS Graphical User Interface (GUI) - You can invoke the EMS interface from the

Resource Management icon in System Administration Manager (SAM). From the EMS

graphical user interface (GUI), you can create, modify, and remove monitoring requests.

You can also view the list of available resources that EMS has discovered on your system,

and a list of all currently configured monitoring requests.

• EMS Command Line Interface (CLI) - You can invoke the EMS command-line

interface by typing emscli with the appropriate option at the HP-UX command-line

prompt. You can use the emscli command-line utility to create, modify, and remove

monitoring requests. You can also view the list of available resources that EMS has

discovered on your system, and a list of all currently configured monitoring requests. It is

also enabled with a help feature, emscli -h, to view the usage of various options

supported by emscli. For more information on the command line options supported by

emscli, refer to the emscli(1m) manpage.
