1.2.2 Collecting performance data by attribute
In PFM - RM for Platform, performance data is collected in a format called records. A record is a unit for storing collected performance data in a database.
The types of performance data that can be collected have already been defined in PFM - RM for Platform. You use PFM - Web Console to select the records you wish to have collected. For details about how to use PFM - Web Console to select the records to be collected, see the chapter that describes management of operation monitoring data in the JP1/Performance Management User's Guide.
Records are classified into two types, according to the characteristics of the performance data to be collected.
-
Product Interval record type
For records of the Product Interval record type, the system collects performance data for a specified interval, such as the CPU usage rate over 5 minutes. You can use these records to analyze changes or trends in the system status over time.
The Product Interval record type is referred to hereafter as the PI record type.
-
Product Detail record type
For records of the Product Detail record type, the system collects performance data that indicates the system status at a specific point in time, such as detailed information about a host that is currently being monitored. You can use these records to obtain a snapshot of the system status at a particular time.
The Product Detail record type is referred to hereafter as the PD record type.
Each record is further divided into smaller units called fields. In Performance Management, records and fields are referred to collectively as a data model. For details about each record, see 7. Records.
