1.1.2 Collect performance data according to its characteristics
PFM - Agent for Enterprise Applications collects performance data in records. Each record consists of smaller units called fields. Records and fields are referred to collectively as the data model.
Records are classified into two types according to their characteristics. The record types that are used to collect performance data are predefined in PFM - Agent for Enterprise Applications. The user simply uses PFM - Web Console to specify the performance data records to be collected.
PFM - Agent for Enterprise Applications supports the following two record types:
-
Product Interval record type (referred to hereafter as the PI record type)
For records of the PI record type, the system collects performance data for a specified interval, such as the number of processes in one minute. You can use these records to analyze changes or trends in the system status over time.
-
Product Detail record type (referred to hereafter as the PD record type)
For records of the PD record type, the system collects performance data that indicates the system status at a specific point in time, such as detailed information about the currently active processes. You can use these records to obtain the system status at a particular time.
For more information about record types, see Chapter 10. Records.
