Customizing the display of the Probable Cause Analysis list

General

View

Displays the events sorted by score or by device. The default view is By

Score.

• By Score: displays the events sorted on the score.
• By Device: displays the events sorted by devices of the events.

Time

Enables the time specification based on the secondary event time out interval. The default time interval is -1 and +30.

Events Filter

Enables the levels of event filter for the following options:

• Level 1
• Level 2
• Level 3
• Level 4

By default, level1 is displayed.

Analysis

Enables you to correlate information in the following ways:

• Time Correlation - enables you to display the secondary events in the same timeframe as the primary event.
• Data Correlation - enables the computation of data using the data collected for the resulting event and the probable cause event. Data correlation is applicable only to internal events.
• Correlate metric data within time window - co-relates the metric data of the primary event against the metric data of each candidate event. Only the metric data within the analysis window is analyzed.
  For example, if you select - 1 hour and + 1 hour in the time window slider, then up to 2 hours of data are analyzed.
• Correlate metric data during previous abnormalities on event's metric- co-relates data between the metric of the primary event against other metrics for the time periods at which the primary metric was abnormal in the past. (subject to data retention limits). This can produce more accurate data correlation results at the cost of increased processing time. However, the results may take up to 3 times longer to return.

Event Filter Levels

Filter levels on non-KPI metrics

Select this option to filter by non-Key Performance Indicators (KPI).

Show only highest scoring event per metric

Select this option to display only the event with the highest score. For a given metric there could be multiple abnormalities and threshold events.

Filter using service model

Select this option to filter events based on the impact relationships defined for the CI associated with the primary event.

Displays event outside the model, but lower scores

Select this option to show the events that are not associated with the impacting CI's based on the model identified above.

Filter using global relationships

Select this option to control whether the built-in global relationships are used to determine probable cause.

Filter events not associated with a computer system or CI

Select this option to filter an event that is not associated with a device or a CI

Filter events scoring less than

Select this option to filter events with a score lower than that entered in this field. After the probable cause analysis identifies the probable cause events, each event is scored and only the events whose score is above the specified limit are shown as root cause in the probable cause analysis page.

Advanced

By Score - Max Number of Events to Display

Enables you to determine the maximum number of events to display in the PCA results window based on the score of the events.

By Device - Max Number of Devices to Display

Enables you to determine the maximum number of devices to display in the PCA results window.

By Device - Max Number of Events per Device to Display

Enables you to determine the maximum number of events per device to display in the PCA results window.
