Spotlight on Oracle 10.4 - Release Notes

Processes Page

The Processes page contains a table (grid) that lists all Windows processes that are currently running on the system. (A process is one instance of an application program that is currently executing on the Windows machine.)

To open the Processes page

  1. Select the Spotlight on Windows connection in the Spotlight Browser.
  2. Click Processes | Processes.

Note: Not all of these columns will be visible by default. To view hidden columns, right-click a column heading and choose Organize Columns... from the shortcut menu. Show, Hide & Order Columns

Column Description

Process

The image name of the application. This can be used as a parameter in system programs, such as the TASKKILL.EXE command on Windows systems.

Notes:

  • Click on a process to display sub pages. Process Details Page
  • Right click on the process and select End Process (if enabled) to end any processes currently running on the monitored machine (local or remote).
  • Right click on the process and select Diagnose Process (if enabled) to select the processes to monitor performance of in the Single Application drilldown. Windows Applications Metrics
  • Some of the processes may be running other, secondary, processes. Right click the grid and select Show as Tree to display the secondary processes as branches of the initial process.

PID

Process ID. This is unique to each process running on the system. This can be used as a parameter in system programs, such as the TASKKILL.EXE command on Windows systems.

% CPU

The percentage of CPU time that the process is currently consuming. This is an instantaneous result.

Memory Usage (MB)

The current size of the working set of the process.

Virtual Memory Size (MB)

The current memory allocated to the process that cannot be shared with other processes.

Elapsed time

How long it has been since the process was started.

Handles

The overall number of resources that the process currently has open. A handle is a value used to uniquely identify a resource so that a process can access it.

Threads

The number of active threads in the process. A thread is a process execution unit.

Page Faults/sec

An instantaneous view of how many page faults are occurring for the process.

IO/sec

Shows the number of IO accesses (such as hard disk reads and writes and memory reads and writes) being performed by the process.

% Kernel

The percentage of CPU time that the process is currently consuming in privileged mode. (Privileged mode is designed for operating system components and allows direct access to hardware and all memory.)

% User

The percentage of CPU time that the process is currently consuming in user mode. (User mode is a restricted processing mode designed for applications, environment subsystems, and integral subsystems.

Affinity

For systems with multiple CPUs, the process affinity, which can be set via the Windows Task Manager, specifies the CPUs that are permitted to run the current process.

Use the Configure affinity option to tell Spotlight on Windows about the CPUs where the specified process is permitted to run. This enables Spotlight to report the CPU usage for that process with accuracy.

Right click on the process and select Configure Affinity (if enabled). Process Affinity Dialog

Note: Spotlight itself CANNOT set process affinity. The Processes Page And Process Affinity

IO data bytes/sec

The rate at which the process is reading and writing bytes in all its I/O operations.

IO other bytes/sec

The rate at which the process is issuing bytes to I/O operations that do not involve data (control operations, for example).

IO other operations/sec

The rate at which the process is issuing I/O operations that do not involve data (control operations, for example).

IO read bytes/sec

The rate at which the process is reading bytes from I/O operations.

IO Reads/sec

Shows the number of IO reads (such as hard disk reads and memory reads) being performed by the process.

IO write bytes/sec

The rate at which the process is writing bytes to I/O operations.

IO Writes/sec

Shows the number of IO writes (such as hard disk writes and memory writes) being performed by the process.

Page file bytes

The current number of bytes that this process has used in the paging file(s).

Page file bytes peak

The maximum number of bytes that this process has used in the paging file(s).

Parent ID

The ID of the process that created the current process.

Peak Address Space (MB)

The peak size of the total address space of the process since it was started.

Peak Memory Usage (MB)

The peak size of the working set of the process since it was started.

Pool nonpaged bytes

The number of bytes of memory currently used by the server that cannot be paged out.

Pool paged bytes

The number of bytes of memory currently used by the server that can be paged out.

Priority

The priority of the process. Program priorities range from 1 to 31, and are dependant upon what the process is currently executing. Processes started in "Real Time" mode run with a priority of 16 to 31, whereas processes with "High", "Normal" or "Low" settings run in a priority range of 1 to 15.

Services

The services (if any) associated with the current process permitted to run the current process.

User

The owner of the process on the Windows Server.

Virtual Address Space (MB)

The current size of the total address space of the process.

Note: A process is limited to 2GB of address space no matter how much free RAM may be available.
