Job Management Partner 1/Performance Management - Agent Option for Platform Description, User's Guide and Reference
For records of the PI record type, two types of data are stored in the Store database: the data collected at the interval set in Collection Interval, and the data summarized for a specific period of time (minute, hour, day, week, month, or year) according to a predefined rule. The type of summarization is defined for each field. This definition is called a summarization rule.
Depending on the summarization rule, intermediate data used during the summarization period must sometimes be retained. In this case, a field for holding the intermediate data is added to a record in the Store database. This field is called an added field.
Part of an added field is displayed as a record field in PFM - Web Console. The added fields displayed on PFM - Web Console can be used as the fields to be displayed in a historical report.
To differentiate them from the fields that are added through summarization, the fields described in the explanation of each record in this chapter are called fixed fields.
The following field names are used for added fields:
- Added field name stored in the Store database
A field name consisting of the PFM - Manager name in the fixed field and an added suffix
- Added field name displayed on PFM - Web Console
A field name consisting of the PFM - View name in the fixed field and an added suffix
The table below shows the suffixes to be added to the PFM - Manager name, the corresponding suffixes to be added to the PFM - View name, and the data stored in the fields.
Table 5-3 List of suffixes for added fields
PFM - Manager name PFM - View name Stored data _TOTAL (Total) Total field value of the records within the summarization period _TOTAL_SEC (Total) Total field value of the records within the summarization period (for a utime field) _COUNT -- Number of records collected within the summarization period _HI (Max) Maximum field value of the records within the summarization period _LO (Min) Minimum field value of the records within the summarization period
- Legend:
- --: No added field
The table below shows a list of summarization rules.
Table 5-4 List of summarization rules
Summarization rule name Summarization rule COPY Stores the field value of the latest record within the summarization period without any modification. AVG Stores the average field value within the summarization period.
The computation formula follows:
(total-field-value)/(number-of-collected-records)
- Added fields (Store database)
- _TOTAL
- _TOTAL_SEC (for a utime field)
- _COUNT
- Added field (PFM - Web Console)#1, #2
- (Total)
ADD Stores the total field value within the summarization period. HI Stores the maximum field value within the summarization period. LO Stores the minimum field value within the summarization period. HILO Stores the maximum, minimum, and average of the data within the summarization period.
An average value is stored in the fixed field.
The computation formula follows:
(total-field-value)/(number-of-collected-records)
- Added fields (Store database)
- _HI
- _LO
- _TOTAL
- _TOTAL_SEC (for a utime field)
- _COUNT
- Added fields (PFM - Web Console)#1, #2
- (Max)
- (Min)
- (Total)
% Stores the average field value within the summarization period.
Applied primarily to percentage fields.
The computation formula follows:
(total-field-value)/(number-of-collected-records)
- Added fields (Store database)
- _TOTAL
- _TOTAL_SEC (for a utime field)
- _COUNT
-- No summarization
- #1
- A utime field containing _AVG in the PFM - Manager name cannot use a (Total) field added to PFM - Web Console in a historical report.
- #2
- A field containing any of the following character strings in the PFM - Manager name cannot use a (Total) field added to PFM - Web Console in a historical report:
- _PER_, PCT, PERCENT, _AVG, and _RATE_TOTAL
