Summarization rules

For records of the PI record type, the data that is collected is stored in the Store database. This includes data collected at the interval set in Collection Interval, as well as data that is collected on a specific interval basis derived from defined rules (such as minute, hour, day, week, month, or year). The type of summarization is defined for each field; this definition is referred to as the summary rules.

Some summary rules require intermediate data to be retained during the summarization period. In such a case, a field for retaining the intermediate data is added to the record in the Store database; this is called an added field. Some added fields are displayed as record fields in PFM - Web Console. These added fields that are displayed in PFM - Web Console can be used as fields for display in historical reports.

As distinguished from the added fields that are created by summarization, the fields described in each record explanation are called fixed fields.

The name of an added field is as follows:

The following table lists the suffixes for the PFM - Manager name, the suffixes for the corresponding PFM - View name, and the data that is stored in each field.
