Method Details

__init__(self, name='ProcessMonitor')
(Constructor)

source code 

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Overrides: object.__init__
(inherited documentation)

add_process_listener(self, l)

source code 

Listener for process events. MUST be called before ProcessMonitor is running.See ProcessListener class.

Parameters:

register(self, p)

source code 

Register process with ProcessMonitor

Parameters:
Raises:
  • PmonException - if process with same name is already registered

register_core_proc(self, p)

source code 

Register core process with ProcessMonitor. Coreprocesses have special shutdown semantics. They are killed after all other processes, in reverse order in which they are added. @param p Process

Parameters:
Raises:
  • PmonException - if process with same name is already registered

registrations_complete(self)

source code 

Inform the process monitor that registrations are complete. After the registrations_complete flag is set, process monitor will exit if there are no processes left to monitor.

has_process(self, name)

source code 
Returns: bool
True if process is still be monitored. If False, process has died or was never registered with process

get_process(self, name)

source code 
Returns: Process
process registered under  name, or None

kill_process(self, name)

source code 

Kill process that matches name. NOTE: a killed process will continue to show up as active until the process monitor thread has caught that it has died.

Parameters:
  • name (str) - Process name
Returns: bool
True if a process named name was removed from process monitor. A process is considered killed if its stop() method was called.

get_process_names_with_spawn_count(self)

source code 
Returns: [[(str, int),], [(str,int),]]
Two lists, where first list of active process names along with the number of times that process has been spawned. Second list contains dead process names and their spawn count.

run(self)

source code 

thread routine of the process monitor.

Overrides: threading.Thread.run
