Processes mode in the Timeline view provides a similar set of data to the output of the top command in your Linux shell. For every time bin in the Timeline view, it provides a list of processes along with usage information.
The details panel has the following columns when it is in Processes mode:
The order in which rows were added to the table. This column is the default sort order.
The PID that Linux assigned to the process.
The name of the process.
The average percentage of the CPU activity that this process used over the range that the cross-section marker covers.
You can sort by any of the columns in Processes mode. Click for a descending sort and click again to reverse the sort.
