1.1.2 Collecting performance data according to its characteristics
PFM - Agent for Service Response 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 three types according to their characteristics. The record types that are used to collect performance data are predefined in PFM - Agent for Service Response. The user simply uses PFM - Web Console to specify the performance data records to be collected.
PFM - Agent for Service Response supports the following three 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 per 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 processing. You can use these records to obtain a snapshot of the system status at a particular time.
-
Product Log record type (referred to hereafter as the PL record type)
For records of the PL record type, the system collects the log and the messages on applications that are being executed.
For details about each record type, see 10. Records.
