public class ProcPsParser extends Object
/proc/[PID]/stat
files. The samples contain status
information about processes (PID, command, state, PPID, user and system
CPU times, etc.).
Method Summary | |
---|---|
static int | getState(String state)
Returns the process state. |
static PsStats | parseLog(InputStream is, Map pidNameMap, Map forkMap)
Parses the proc_ps.log file. |
Parameters: state process state string
Returns: process state
proc_ps.log
file. The output from
/proc/[PID]stat
is used to collect process
information.
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: process statistics
Throws: IOException if an I/O error occurs
