Method Details

init(self, run_id, name, server_uri, machine, master_uri=None, sigint_timeout=15.0, sigterm_timeout=2.0)
(Constructor)

source code


:param machine: Machine instance. Must be fully configured.
    machine.env_loader is required to be set.
:param sigint_timeout: The SIGINT timeout used when killing nodes (in seconds).
:type sigint_timeout: float
:param sigterm_timeout: The SIGTERM timeout used when killing nodes if SIGINT does not stop the node (in seconds).
:type sigterm_timeout: float

Overrides: object.__init__

start(self)

source code

Start the remote process. This will create an SSH connection to the remote host.

Overrides: pmon.Process.start

is_alive(self)

source code


:returns: ``True`` if the process is alive. is_alive needs to be
    called periodically as it drains the SSH buffer, ``bool``

Overrides: pmon.Process.is_alive

stop(self, errors=None)

source code

Terminate this process, including the SSH connection.

Parameters:

errors - error messages. stop() will record messages into this list.

Overrides: pmon.Process.stop
