ironic_python_agent.agent module

class ironic_python_agent.agent.Host(hostname, port)

Bases: tuple

hostname

Alias for field number 0

port

Alias for field number 1

class ironic_python_agent.agent.IronicPythonAgent(api_url, advertise_address, listen_address, ip_lookup_attempts, ip_lookup_sleep, network_interface, lookup_timeout, lookup_interval, standalone, agent_token, hardware_initialization_delay=0, advertise_protocol='http')

get_status()

Retrieve a serializable status.

Returns:

min_jitter_multiplier = 0.3

run()

Start the heartbeat thread.

stop()

Stop the heartbeat thread.

class ironic_python_agent.agent.IronicPythonAgentStatus(started_at, version)

Bases: Serializable
