Optimization and Fault Symptom Analysis
The Fault Signature Analysis (FSA) option enables the aggregation of alarms that share common "suspect" FRUs. The FSA module collects the events and summarizes them into fewer and more specific, actionable events. The collection of events often points to a root cause of a problem, whereas single events are merely symptoms of the problem.
When Fault Signature Analysis is enabled, a one-probing cycle delay ensures that all slaves have reported their events to the master agent. For example, if the agent is set to run every 5 minutes, then 10 minutes are required for the first FSA.
Fault Signature Analysis delays event generation by one agent run. This ensures that all events are generated before the correlation cycle begins.
Aggregating Events Using Fault Signature Analysis
- Click the Optimization/FSA link on the General Maintenance menu.
The Optimization/FSA window is displayed.
- Click the Fault Signature Analysis check box.
The module creates new aggregated events by grouping events together that share common suspect FRU's.
- Click Update Options.

Parallel Monitoring enables the user to probe more than one device at the same time. This can be used to accelerate the monitoring frequency. Parallel monitoring is limited to switches and Sun StorEdge storage arrays.
