Process Detail (PD)
- Organization of this page
Function
The Process Detail (PD) record stores the performance data at a given point in time on a single process's paging, memory, time usage, and the like.
While processes continue to exist or PFM - Agent for Platform remains active, this record is created for each process that newly becomes active every time a record is collected. The performance data stored in this record is the same as that stored in the Process Detail Interval (PD_PDI) record if the updating interval is the same. However, if performance data collected at a point in time is the same as the performance data collected in the previous interval for the same process, performance data is stored in the same record, overwriting the data in the database. This point is different from the Process Detail Interval (PD_PDI) record.
This is a multi-instance record.
- Notes:
-
-
Each process represents a program that is being executed during data collection.
-
If a new record corresponding to the Program (INSTANCE) field is generated during a collection interval, 0 is displayed as the first value for the following fields, because their values are computed from the information collected during the previous collection interval:
• CPU % (PCT_PROCESSOR_TIME)
• IO Data Bytes/sec (IO_DATA_BYTES_PER_SEC)
• IO Data Operations/sec (IO_DATA_OPERATIONS_PER_SEC)
• IO Other Bytes/sec (IO_OTHER_BYTES_PER_SEC)
• IO Other Operations/sec (IO_OTHER_OPERATIONS_PER_SEC)
• IO Read Bytes/sec (IO_READ_BYTES_PER_SEC)
• IO Read Operations/sec (IO_READ_OPERATIONS_PER_SEC)
• IO Write Bytes/sec (IO_WRITE_BYTES_PER_SEC)
• IO Write Operations/sec (IO_WRITE_OPERATIONS_PER_SEC)
• Page Faults/sec (PAGE_FAULTS_PER_SEC)
• Privileged CPU % (PCT_PRIVILEGED_TIME)
• User CPU % (PCT_USER_TIME)
-
If the value in the Program (INSTANCE) field of this record is System or Idle, the data for the Elapsed Time (ELAPSED_TIME) field may not be correctly collected. In this case, the value for the Elapsed Time (ELAPSED_TIME) field is close to the value for the System Up Time (SYSTEM_UP_TIME) field of the System Overview (PI) record, so utilize this value.

A value between 0 and 32,767 seconds can be specified (a value within the range specified for Collection Interval). Use this item to distribute the collection load, because executing data collection all at once results in concentration of the processing workload. Note that the data collection duration to be recorded is the same as the Collection Interval, regardless of the value specified for Collection Offset.
