def __call__(self, event): (source)
from twisted.logger.ILogObserver

Log an event.

Parameters
event:LogEvent

A dictionary with arbitrary keys as defined by the application emitting logging events, as well as keys added by the logging system. The logging system reserves the right to set any key beginning with the prefix "log_"; applications should not use any key so named. Currently, the following keys are used by the logging system in some way, if they are present (they are all optional):

  • "log_format": a PEP-3101-style format string which draws upon the keys in the event as its values, used to format the event for human consumption.
  • "log_flattened": a dictionary mapping keys derived from the names and format values used in the "log_format" string to their values. This is used to preserve some structured information for use with twisted.logger.extractField.
  • "log_trace": A list designed to capture information about which LogPublishers have observed the event.
  • "log_level": a log level constant, indicating the importance of and audience for this event.
  • "log_namespace": a namespace for the emitter of the event, given as a str.
  • "log_system": a string indicating the network event or method call which resulted in the message being logged.
