Missing config option mode in monitoring.ini

[duelle]

The monitoring fails with an exception due to a missing configuration option in the monitoring.ini.
It seems to expect an option mode in the [General] section, which is neither present, nor documented.

I assume that said option is supposed to hold either tcp or text as its value. If there is no such option named mode, the monitoring crashes:

kieker-lang-pack-python/kieker/monitoring/controller.py

Lines 92 to 98 in 4c6c5c1

	mode = config_parser.get('General', 'mode')
	if mode == 'tcp':
	self.monitoring_writer = TCPWriter(config)
	elif mode == 'text':
	self.monitoring_writer = FileWriter(config_parser.get('FileWriter', 'file_path'), [])
	else:
	self.monitoring_writer = DummyWriter()

The monitoring.ini in the current version does not hold such a configuration option:
