Limiting the flow of events in the operator console

To enable or disable non-KPI metrics

1. On the Event Reduction screen, clear the Enable Abnormality Detection and Baseline Generation for non-KPI metrics check box to stop further baseline projection and abnormality detection for non-KPI attributes.

   Note

   By default, for fresh installations, the Enable Abnormality Detection and Baseline Generation for non-KPI metrics check box is disabled. However, for upgrade customers, this check box maintains the same non-KPI status that it had before the upgrade. For example, if the check box was enabled before the upgrade, it remains enabled.

2. Click Apply.

To enable baselines and abnormality detection for non-KPI metrics

For baselines to be generated for an attribute, that attribute must have an active abnormality threshold. An active abnormality threshold means that the threshold exists and is not suppressed. By default, metrics that are not Key Performance metrics (non-KPI metrics) do not have an active abnormality threshold, so baselines are not set automatically for non-KPI metrics. If you want to generate baselines for non-KPI metrics, you must enable baseline generation for these metrics.

If the baseline generation is not enabled for non-Key Performance Indicator (KPI) metrics, only those attributes that have an active abnormality threshold and are also KPI attributes have baselines generated for them.

Absolute thresholds (with "outside baseline") or signature thresholds do not satisfy these requirements.
To enable or disable abnormality detection and baseline generation for non-KPI metrics

1. From the Operations Console toolbar, choose Options.
2. Choose the Administration tab.
3. In the Event Administration section, click the Edit link for Intelligent Event Reduction.
4. On Intelligent Event Reductionscreen, select from one of the following actions:
   • To enable baselines and abnormality detection for non-KPI metrics, select the Enable Abnormality Detection and Baseline Generation for non-KPI metrics check box.

   • To stop further baseline projection and abnormality detection for non-KPI metrics (which is disabled by default), clear the Enable Abnormality Detection and Baseline Generation for non-KPI metricscheck box.

     Note

     When the Enable Abnormality Detection and Baseline Generation for non-KPI metrics check box is selected, baselines are generated for KPI attributes irrespective of the presence of abnormality thresholds.
     
     When the check box is not selected, baselines are generated for both KPI and non-KPI attributes that have abnormal thresholds.

5. Click Apply.
   
   Turning on baselines and abnormality detection for non-KPI metrics can have a significant impact on the performance and scalability of the BMC TrueSight Infrastructure Management Server. Baselines and abnormalities are designed to be used with KPI metrics in order to provide the greatest value.
