What’s in This Version

The A.04.00.01 version of High Availability Monitors for HP-UX 11i v2 operating system runs

on the Itanium 2-based platform.

HA Monitors contains a suite of monitors. Among them, MIB Monitor is used for monitoring

the availability of LAN interface. In HP-UX 11i v2, with introduction of IPv6, there are new

interface monitoring MIBs. The MIB Monitor has been enabled to use the newer MIBs on

IPv6-enabled systems.

All the HA Monitors libraries are available as PA libraries.

The Event Monitoring Service contains the following:

• The 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.

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

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

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.

• The 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. 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.

• The resls and resdata EMS utilities.

Deﬁne monitoring requests through EMS GUI, EMS CLI or with high availability software,

such as MC/ServiceGuard and ServiceGuard Extension for RAC (formerly known as

ServiceGuard OPS Edition). The EMS framework (either through the EMS GUI, EMS CLI or

through MC/ServiceGuard) displays a list of conﬁgured monitoring requests.

Using the EMS GUI, EMS CLI or the MC/ServiceGuard, you can conﬁgure more than one

monitoring request for each HA Monitor. For example, you may want to send a notiﬁcation to

syslog with one value and also send an email message with another value.
