Creating a Custom Metric Family › Understanding the Metric Family XML Structure › BaselineDefinitions

BaselineDefinitions

The BaselineDefinitions section contains the baseline definitions to calculate for this metric family. A baseline definition must be specified for each metric in the AttributeGroup section whose Baseline property is set to true.

You can define two types of baselines: Hourly (required) and Daily (optional). Hourly baselines are used both for event processing and for displaying baselines in reports. Daily baselines are used for displaying baselines in reports with a time frame of one month or greater.
