loggerCallbacksLocal: List[Tuple[Callable, Callable]] = []

static registerCallback(callback, thresholdSeverity=4)

Register the specified ‘callback’ that will be called for all log messages with severity greater than or equal to the specified ‘thresholdSeverity’. The callback needs to be registered before the start of all sessions. If this function is called multiple times, only the last registered callback will take effect.
