Setting and Modifying Alarm Sensitivity Levels

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 .

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