Event Monitoring Service Version A.04.10 Release Notes

What’s in This Version

Chapter 16

— 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.

EMS can be used with HP OpenView, Serviceguard, and any other software that can receive

SNMP traps, TCP, or UDP protocol messages.

You can write your own monitors using the EMS Developer’s Kit. The manual and software

can be downloaded free from the Website http://www.software.hp.com . Select High

Availability, and then choose Event Monitoring Service Developers’ Kit.

Conﬁguring Serviceguard EMS Resource Dependencies

In the earlier versions of Serviceguard, it was possible to conﬁgure the EMS resource package

dependencies via SAM from the “Package Conﬁguration” subarea. Since the “Package

Conﬁguration” subarea in SAM is no longer supported in Serviceguard version A.11.15.00 and

later versions for HP-UX 11i v2, an alternate procedure for conﬁguring EMS resource package

dependencies have been provided. Refer to Serviceguard version A.11.15.00 Release Notes on

HP-UX 11i v2 (http://docs.hp.com) for the alternate procedure.

Bastille Interactions

EMS requires SNMP daemon (snmpd) to query SNMP MIBs and to send SNMP trap

notiﬁcations. Selecting an install-time security level causes the SNMP daemon (snmpd) to be

shutdown.Therefore, if your system is conﬁgured with any install-time security level, any

SNMP MIB-related query or SNMP trap notiﬁcation will fail. The same behavior will result if

snmpd is disabled manually or by using a tool such as HP-UX Bastille.

If you want to secure the system using HP-UX Bastille interactively, ensure that the SNMP

daemon service is not disabled for EMS to function properly. Alternatively, after using an

install-time security level, you can manually start the snmp daemon and related snmp

subagents mib2agt, hp_unixagt, trapdestagt and ipv6agt (if your system supports IPv6).
