6.9.3 Notes on evaluating alarms

This subsection provides cautionary notes on alarm evaluation.

Organization of this subsection

(1) Limitation on the number of instances evaluated in an alarm

If multi-instance records are collected in PFM - Agent or PFM - RM, the maximum number of instances handled by a collection is 32,767. When alarms are bound to PFM - Agent or PFM - RM, up to 32,767 instances are evaluated. More than 32,767 instances cannot be evaluated.

(2) Interval for evaluating the alarm

An alarm is evaluated at fixed intervals. The interval is the record collection interval for each agent. For details on the collection interval of each record, see the appropriate chapters (the Collection Interval value of each record) that describe records of each PFM - Agent or PFM - RM manual.

To modify the record collection interval, perform the following procedure:

  1. From the Web browser of the monitoring console, log on to PFM - Web Console.

  2. In the navigation frame of the main window, select the Services tab.

  3. Select the monitoring agent that the alarm is bound to.

  4. In the method frame, select Properties.

  5. Expand the Detail Records or Interval Records folder.

  6. Change the value of the Collection Interval property.

  7. The record (performance data) collection interval changes to the value you set.

(3) Character encoding during alarm evaluation

If you use Japanese or Chinese in an alarm definition, the instance of PFM - Agent or PFM - RM to which the alarm table is bound must use the same character set as PFM - Manager. If the agent or PFM - RM uses a different character set, the following can occur:

The character set used by the Performance Management services is determined as follows:

(4) Evaluating alarms when PFM - Agent or PFM - RM is stopped

When PFM - Agent or PFM - RM is stopped, alarms are evaluated as follows.
