Announcement
Event Monitoring Service™ (EMS) version A.04.20.11.01, A.04.20.23.01, and A.04.20.31.01 is being
released for use on the Integrity and PA-RISC platforms with the HP-UX 11i v1, HP-UX 11i v2,
and HP-UX 11i v3 operating system respectively.
You can use EMS together with one or more EMS monitors to monitor various system resources.
The EMS product includes the framework and general monitors. You can configure EMS to
monitor system resources through monitoring requests. In the monitoring request, you define
how and when you want to be notified about system resource events. EMS can enhance your
high availability environment by warning you about a single point of failure before it can make
an application unavailable.
Monitors that register with the EMS framework are automatically discovered and displayed on
the EMS interface. All monitors are bundled with EMS dictionary files and can be found in the
/etc/opt/resmon/dictionary directory.
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
fulfilled.
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.
• Management Information Base (MIB) Monitors - The following Management Information
Base (MIB) monitors are provided with the EMS framework:
— HA Cluster Monitor checks the status of clusters, nodes, packages, and services of
Serviceguard.
— HA Network Interface Monitor reports the status of LAN interfaces.
— HA System Resource Monitor checks the number of users, the system load, and the
amount of file system space.
• The resls and resdata EMS utilities.
