arcor2-logger 0.2.0

ARCOR2 Logger service.

arcor2_logger

The service provides logging capabilities through the network. Logging-related methods are added to ObjectTypes using a mixin class.

• Messages are sent using the websockets protocol.
• Calls to log_ methods are non-blocking.

Example usage

from typing import Optional

from arcor2.object_types.abstract import Generic, Settings

try:
    from .logging_mixin import LoggingMixin  # this is used within an execution package
except ImportError:
    from arcor2_logger.object_types.logging_mixin import LoggingMixin  # this is used during development
    
class MyObject(LoggingMixin, Generic):

    _ABSTRACT = False

    def __init__(self, obj_id: str, name: str, settings: Optional[Settings] = None) -> None:
        super().__init__(obj_id, name, settings)
        self.logger = self.get_logger()
        self.logger.info("Initialized.")

Environment variables

• ARCOR2_LOGGER_URL=ws://0.0.0.0:8765 - by default, the service listens on port 8765.
• ARCOR2_LOGGER_LEVEL=info - by default, messages from objects with level info and higher are logged.
  • Other possible values are warning, error and debug.
