After you have successfully generated a report, Streamline opens it automatically and displays the Timeline view.
The Timeline view breaks up its data into bins, a unit of time defined by the unit drop down menu at the top of the view. For example, if the unit is set to 100ms, every point in the charts and every color-coded bin in the processes section represents trace data captured during a 100ms window.
The Timeline view contains calipers that you can use to set
the specific window of time on which you want to focus. Streamline
updates each report based on where the in and out marker are set,
so if you wanted to focus on the second or so
drag the left caliper to the left boundary of threads activity and
the right caliper to the right boundary. To locate this period of
threads execution, study the processes section of the Timeline view.
The threads process is bright red during
the time it ran.
The Processes section of the Timeline view shows you the active processes in each bin. The entries are derived from process/thread trace data from the Linux kernel scheduler. Weighted colors reflect approximate allocation.
- Yellow to red
Responsible for some percentage of total instructions during this bin. Red indicates a higher percentage.
Notice that in the
threads example, all
bins are white until the process starts. When
threads has started,
the bins turn bright red.
