3.3.2 Effects of a PFM - Manager failure

A shutdown of PFM - Manager has effects on the entire Performance Management system.

PFM - Manager provides centralized management of the agent information for PFM - RM for Platform that is running at each node. It also controls alarm event notifications when thresholds are exceeded during performance monitoring by PFM - RM for Platform as well as execution of actions based on alarm events.

The following describes the effects of a PFM - Manager shutdown on PFM - RM for Platform.

Effects

If PFM - Manager shuts down while PFM - RM for Platform is running, the effects described below result. Note that collection of performance data continues.

Because alarm events cannot be reported to PFM - Manager, alarm events are retained for each alarm definition. PFM - RM for Platform retries notification until PFM - Manager starts. When the number of retained alarm events exceeds 3, the oldest alarm event is overwritten. If PFM - RM for Platform is shut down, the retained alarm events are deleted.

Any notification of alarm status already sent to PFM - Manager is reset when PFM - Manager restarts. The alarm status is refreshed after PFM - Manager has checked the status of PFM - RM for Platform.

Shutting down PFM - RM for Platform takes a while because no notification of this event can be sent to PFM - Manager.

Action

Start PFM - Manager. An active PFM - RM for Platform can continue its operation. However, alarms may not be notified as expected.

After PFM - Manager has been recovered, check the common message log for the KAVE00024-I message.

Evaluate the operation method, taking into account the effects of PFM - Manager shutdown. In addition to problems, events such as configuration change and maintenance may require shutdown of PFM - Manager. We recommend that you ensure that shutdowns for maintenance purposes be performed only when the shutdown will have the least adverse effects on operations.
