Process History Page

The Process History subpage of the Processes drilldown opens when you click a process in the table (grid) in the Processes page, and then click the Process History tab.

This page shows the recent activity of the selected process in a series of related charts. By default, the charts in the Process History page now record data from the time that Spotlight on Windows was started.

To open the Process Details page

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

  3. Select a process to view its details.
  4. Click Process History

Charts on the Process History subpage

Notes:

  • Every chart has a legend (list of symbols) to its right that describes the various series (line graphs) on the chart.
  • Click an item in the legend to highlight its series (line) in the chart. Click a second time to return the series to its normal appearance.
  • Move the mouse pointer over an item in the legend to view the current value for that series within the chart.
Chart Description
Processor

Shows the percentage of Privileged and User Time.

High Privileged time means that the program is predominantly busy accessing resources through operating system requests.

High User time means that the program is predominantly CPU-bound with the program code itself.

Read/Writes

Reads / Second — Shows the rate of IO reads (such as hard disk reads and memory reads) being performed by the process.

Writes / Second — Shows the rate of IO writes (such as hard disk writes and memory writes) being performed by the process.

Memory

Shows the current memory allocated to the selected process.

Memory Usage — Shows the current size of the working set of the selected process. The working set is the set of memory pages touched recently by the threads in the process.

Virtual Memory Size — Shows the current size of the memory allocated to this process that cannot be shared with other processes.

Page Faults Shows the number of page faults being generated by the program. A consistently high value may indicate a lack of memory. However, this metric includes both soft and hard page faults; as such, there may be no associated problems.

Note: The time frame displayed in the charts will depend on the historical settings you have chosen. See History Browser for more information.
