Process Detail Interval (PD_PDI)

Function

The Process Detail Interval (PD_PDI) record stores the performance data per unit time on a process. A record is created for each process ID within the system.

The performance data stored in this record is the same as that stored in the Process Detail (PD) record. 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 not stored in the same record, and a new record is created. This point is different from the Process Detail (PD) record. Therefore, multiple records are created for the same process. After performance data is collected at a given point in time, if the process is terminated before the next performance data is collected, no performance data is collected on that process.

When this record is collected on a real-time basis, performance data on all processes that are being executed by the system is stored. This is a multi-instance record.

Notes:

In AIX and Solaris, only the data in the fields listed below is collected on defunct processes. For all other fields, either 0 or n/a is displayed.
Accounting Flags, Argument List, End Time, Exit Status, Group, Group ID, Parent PID, PID, Program, Real User, Real User ID, Record Time, Record Type, Snapshot Time, State, Terminal, User, User ID

The Interval (INTERVAL) field of this record is always 0. In the fields that show frequency, average, and percentage, the time elapsed since the process startup is used as the data source. To collect a delta value, the difference between the previous elapsed process time and the current elapsed process time is computed. If no delta value is to be collected, the cumulative elapsed time of the process is used for computation.

In the Priority (PRIORITY) field, process priority is determined based on the size of the number. In Solaris, the greater the number, the higher the priority. In AIX and Linux, the smaller the number, the higher the priority. In HP-UX, the number that indicates priority differs with each process setting. You can use the following command to check the process setting:
export UNIX95=1
ps -eo pid,cls,pri
When cls is one of the following, the smaller the number, the higher the priority:
FIFO
RR
RR2
When cls is one of the following, the greater the number, the higher the priority:
HPUX
RT

Performance data on a terminated process cannot be collected.

If the target process of an instance is a zombie process, 0 is set in the fields listed below for Solaris, and -3 is set for AIX and HP-UX.
User, User ID, Real User, Real User ID, Group, Group ID, Real Group, Real Group ID
