WBEM event subscriptions for HP-UX systems managed by HP SIM 5.x (446752-002, January 2009)

Introduction
Troubles that occur on hardware computing systems are called errors. These errors are cached in
either nonvolatile memory, written to a file, or cached in memory. Various mechanisms have been
created to noti
fy network administrators of the existence of these errors. The most common mechanism
is to have the error available to the SNMP application, which reads the cached data and forwards
the error to a predefined list of IP or system addresses as an SNMP trap.
System information that is
not an error but an indication of system operation can be reported in the same manner.
WBEM is beginning to be the preferred method for reporting system errors and condition. This
information is available for use through WBEM an
d is called error indications, or abbreviated as
indications. Similar to SNMP, the WBEM application can forward these indications to a listing of
addresses, also called subscribers. Common subscribers are system management applications such as
HP Systems I
nsight Manager (HP SIM). A management application must make a proactive request to
be a WBEM subscriber. All WBEM communications and subscription requests use the SSL protocol for
security.
Event Monitoring Service (
EMS
)
on HP
-
UX can be configured to forwa
rd SNMP traps to HP SIM. With
the appropriate software on the HP
-
UX system, EMS can be channeled (wrapped) to WBEM and be
announced as indications to the WBEM subscribers.
This paper describes the software requirements for the HP
-
UX system, how to configur
e EMS for
wrapping the SNMP traps to WBEM, and how to configure HP SIM to subscribe to HP
-
UX systems to
receive the WBEM indications.
