Managing Baselines and Key Performance Indicators

To detect abnormalities on the monitored environment, BMC TrueSight Operations Management calculates baselines per attribute based on values collected over a specified period of time to determine a normal operating range. When the collected values for these parameters are out of range, an alert is triggered. Some attributes are identified by default as Key Performance Indicators and automatically included in the base lining calculation.

Managing baselines

The baseline is the expected normal operating range for an attribute of a monitor. There are two baselines: Baseline High and Baseline Low. Baseline High represents the point at which 95% of the weighted average of the historical values fall below this value for the selected time period; Baseline Low represents the point at which 90% of the weighted average of historical values for the selected time period fall above this line.

Baselines are generated for KPI attributes that have an active abnormality thresholds.

Managing Key Performance Indicators

Starting from v9.5 of BPPM, attributes that have not been initially designated in the KM as Key Performance Indicators (KPIs) cannot be flagged as KPIs from BPPM/TrueSight Operations Management. Although enabling baseline is possible through the Options > Administration > Intelligent Event Thresholds feature available in the Infrastructure Management Server operator console, BMC does not recommend doing it.

Attributes for which the system calculates baselines as well as attributes considered as KPIs are respectively identified in this documentation by the following icons:
