Setting and Modifying Database Alarm Sensitivity Levels in Foglight 5.9.8 and below (4227855)

Note: This Knowledgebase article is relevant to Foglight database cartridges 5.9.7 and below.

Foglight for Oracle has three sensitivity levels that control which alarms are reported:

• Essential — Enables only the most important alarms.
• Normal — Enables a selection of alarms from different rule categories, including all Essential alarms.
• Tuning — Enables all alarms.

You can change the sensitivity level assigned to each agent. If a sensitivity level does not include all the alarms you want to track or includes too many alarms, you can view a list of multiple-severity rules and modify the sensitivity level that is mapped to each severity. Changes made to a sensitivity level affect all agents that are assigned that sensitivity level. If you want to enable or disable alarms for the selected agents, see Enabling or disabling alarms for selected agents in the Foglight database cartridge user guide.

Each agent has its own sensitivity level setting. The default is Normal.

To change the sensitivity level used by an agent:

1. In the Alarms view, click the Sensitivity Level tab.
2. Select the check boxes for agents you want to edit, and then click a sensitivity level button, such as Essential.
3. Click Save changes.

You can view a list of multiple severity rules to see which severities are assigned to which sensitivity level. If desired, you can change the assignments. Changes to sensitivity levels affect all agents.

To view and edit alarms assigned sensitivity levels:

1. In the Alarms view, click the Sensitivity Level tab.
2. Click View rules sensitivity mapping.
3. Review the assignments. Recall that the Normal level includes all alarms assigned to the Essential level, and the Tuning level includes both Normal and Essential alarms.
   If you want a record of the existing settings, click Report and export the settings to a file.
4. Select the check boxes for the rules you want to edit, and then click Set sensitivity
   
5. In the Set Rule dialog box, select a sensitivity level for each severity.
6. Click Set.
   All selected rules are updated with the new assignments.
