Sun Management Center 3.6.1 User's Guide

Alarms Tab in the Attribute Editor

The Alarms tab enables you to set alarms thresholds only for those data properties that have associated simple alarms. Simple alarms use the rCompare rule, which is described in Appendix D, Sun Management Center Software Rules. For information about simple alarms, see Table 10–1.

Simple alarms are based on thresholds. A monitored data property is greater than, less than, not equal to, or equal to a single threshold value. By contrast, complex alarms occur when a set of conditions becomes true. For more information about defining, acknowledging, and working with alarms in Sun Management Center, see Chapter 12, Managing Alarms.


Note –

You need the appropriate security permission to set an alarm threshold. See Chapter 18, Sun Management Center Security for more information.


The following table shows common simple alarm limits for monitored properties. The alarm limits are also displayed in the Parameter Description field. You can set thresholds for one or more of these alarm limits for selected data properties.
