Using EMS HA Monitors

24 Chapter 1

Installing and Using EMS

You may specify the ITO message severity for both normal and abnormal events:

• Normal

• Warning

• Critical

• Minor

• Major

The ITO application group is EMS(HP), the message group, HA, and the object

is the full path of the resource being monitored.

See HP OpenView IT/Operations Administrators Task Guide (P/N

B4249-90003) for more information on conﬁguring notiﬁcation severity.

• SNMP traps

This sends messages to applications using SNMP traps, such as Network Node

Manager. See HP OpenView Using Network Node Manager (P/N J1169-90002)

for more information on conﬁguring SNMP traps. The following traps are used

by EMS:

EMS_NORMAL_OID “1.3.6.1.4.1.11.2.3.1.7.0.1” - Normal notiﬁcation

EMS_ABNORMAL_OID “1.3.6.1.4.1.11.2.3.1.7.0.2” - Abnormal notiﬁcation

EMS_RESTART_OID “1.3.6.1.4.1.11.2.3.1.7.0.4” - Restart notiﬁcation

• TCP and UDP

This sends TCP or UDP encoded events to the target host name and port

indicated for that request. Thus the message can be directed to a user-written

socket program.

Templates for conﬁguring IT/Operations and Network Node Manager to display

EMS events can be found on the Hewlett-Packard High Availability public web page

at http://www.hp.com/go/ha.

What is a Notiﬁcation Comment?

The notiﬁcation comment is useful for sending task reminders to the recipients of an

event. For example, if you have a disk monitor request that reports an alert that an

entire mirror has failed, when that event shows up in IT/Operations, for example,

you may want it to have the name of the person to contact if disks fail. If you have

conﬁgured MC/ServiceGuard package dependencies, you may want to enter the

package name as a comment in the corresponding pv_summary request.
