On the TraceViewerPropertyView, you can check the properties of traces the based on the rules that were defined for line count and variable tracing.
For example, to monitor RAM consumption in
the Kernel, there can be the following kind of trace:
00:11:31:624
[0] Kernel Memory:Initial free RAM;Bytes:127598592
When you create
a variable tracing rule that contains the text Kernel Memory:Initial free
RAM;Bytes, you can view what the latest value of this variable was, as
well as a number of its previous values.
For generic instructions on how to create rules and definitions, see instructions in Setting up rules and filters.
To open the history:
The Variable tracing history dialog is displayed.
In the history, you can see the last n number of events of the variable changing. There is a timestamp (and time from the previous event), new value and the line number where the change happened. The Has codeline column indicates whether or not this item has location metadata available.
Tip: If you close TraceViewer when you have any of the variable tracing rules enabled, they will get automatically enabled the next time you start TraceViewer.
