Event Table view

QNX Toolkit1.1QNX Toolkit User's GuideDeveloperSetup

The Event Table view displays the raw events in table form. When you select an area of the Overview graph, the Event Table view updates to reflect the chosen data.

With this view, you can see every kernel event that occurred during the trace period and the exact order of the events. Because a trace has a large number of events (even in relatively short traces), you may want to use filtering to show only certain events and areas of interest.

Opening the view

Event Table is one of the dashboard views in the System Profiler.

To open the view:

  1. Click QNX SYSTEM PROFILER, then select a .kev file.
  2. Click DASHBOARDS > Event Table.
    The Event Table view is displayed:

The following table describes the data displayed in the Event Table view:
Column Description
Event Event number.
Time (ns) Timestamp when the event occurred in nanoseconds.
Owner Owner of the event.
Type Type of event.
Data Data associated with the event. Often, the PID and TID are included; for message-related events, the message ID is included.
Class Event class.
CPU The CPU that the event relates to.
Cycle CPU cycle.

For more information about events, go to Classes and events in the Events and the Kernel chapter of the System Analysis Toolkit User's Guide.

You can filter each column of the Event Table view.

To filter the view:
