Parses the ps.log file. |
Parameters: procInfo process info map
Returns: process state
ps.log
file. Consecutive ps samples are
parsed and returned in a list. The ps samples are only parsed up to
the point where one of the specified exitProcesses
is
running and the system is idle.
If pidNameMap
is set, it is used to map PIDs to
command names. This is useful when init scripts are sourced, and thus
ps is unable to report the proper process name. A sysinit
modification is necessary to generate the mapping log file.
forkMap
is an optional map that provides detailed
information about process forking.
Parameters: is the input stream to read from pidNameMap PID to name mapping map (optional) forkMap process forking map (optional)
Returns: ps statistics and a list of processes
Throws: IOException if an I/O error occurs
