Summarization rules

For records of the PI record type, data that is collected according to the interval set in Collection Interval is stored in the Store database, together with data that is summarized according to a set period (for every minute, hour, day, week, month, or year) and defined based on a predefined rule. The summary type is defined for each field. This definition is called a summary rule.

For some summary rules, the intermediate data during the summary period must be retained. In such a case, a field for retaining the intermediate data is added to the record in the Store database. This field is called an added field. Part of the added field is displayed as a record field on PFM - Web Console. The added fields displayed on PFM - Web Console can be used as fields to display in a historical report.

To differentiate them from the added fields that are added during summarizing, the fields that are listed in the description of each record in this chapter are called fixed fields.

The following explains the field names of added fields.

Added field name stored in the Store database
The field name has a suffix added to the PFM - Manager name in the fixed field.

Added field name displayed on PFM - Web Console
The field name has a suffix added to the PFM - View name in the fixed field.

The table below shows the suffixes that are added to the PFM - Manager name and the suffixes that are added to the corresponding PFM - View name, and the data that is stored in the field.
