processes_tree contains al list of created processes structured in a recursive way allowing to build a process tree..

It is a list, every item of the list containing the following attributes:

children: <list of dictionaries> contains processes created by a given process. Every subfield contains the same fields (children, name, process_id and time_offset) allowing to build a recursive process tree.
name: <string> process name.
process_id: <string> ID of the process.
time_offset: <integer> first observed. Seconds since execution start.
