Process Detail (PD)
- Organization of this page
Function
The Process Detail (PD) record stores the Performance data showing the status of a process at a given point in time. 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 Interval (PD_PDI) 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 stored in the same record, overwriting the data in the database. This point is different from the Process Detail Interval (PD_PDI) record. 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. Furthermore, no performance data is collected on processes that are not being executed.
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:
-
-
If a process has no terminal name, ?? is displayed in the Terminal (TERMINAL_NAME) field.
-
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, Child Process List, Exit Status, Flags, Group, Group ID, Parent PID, Parent Process List, PID, Process Group ID, Program, Program/PID, Real Group, Real Group ID, Real User, Real User ID, Record Time, Record Type, Scheduler Class, Snapshot Time, Start Time, Terminal, User, User ID, Virtual Env ID (Solaris or AIX)
-
In the Priority (PRIORITY) field, process priority is determined based on 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

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.
When changing the Collection Offset value, specify a value that takes into account the impact of the collection processing load.
