Managing the event log

© Copyright IBM Corp. 2010, 2011
Events that are detected are saved in an event log. As soon as an entry is made in
this event log, the condition is analyzed. If any service activity is required, a
notification is sent.
Event reporting process
The following methods are used to notify you and the IBM Support Center of a
new event:
v If you enabled Simple Network Management Protocol (SNMP), an SNMP trap is
sent to an SNMP manager that is configured by the customer.
v If enabled, log messages can be forwarded from a sender to a receiver on an IP
network by using the syslog protocol.
v If enabled, event notifications can be forwarded from a sender to a receiver
through Call Home email.
v If Call Home is enabled, critical faults generate a problem management record
(PMR) that is sent directly to the appropriate IBM Support Center.
When a significant change in status is detected, an event is logged in the event log.
Error data
Events are classified as either alerts or messages:
v An alert is logged when the event requires some action. Some alerts have an
associated error code that defines the service action that is required. The service
actions are automated through the fix procedures. If the alert does not have an
error code, the alert represents an unexpected change in state. This situation
must be investigated to see if it is expected or represents a failure. Investigate an
alert and resolve it as soon as it is reported.
v A message is logged when a change that is expected is reported, for instance, an
IBM FlashCopy operation completes.
You can view the event log by using the management GUI or the command-line
interface (CLI).
You can view the event log by using the Monitoring > Events options in the
management GUI. The event log contains many entries. You can, however, select
only the type of information that you need.
You can also view the event log by using the command-line interface (lseventlog).
See the "Command-line interface" topic for the command details.
The event log has a limited size. After it is full, newer entries replace entries that
are no longer required.
