	# If you are running more than one instances of graylog2-server you have to select one of these			############################
				# GRAYLOG CONFIGURATION FILE
				############################
				#
				# This is the Graylog configuration file. The file has to use ISO 8859-1/Latin-1 character encoding.
				# Characters that cannot be directly represented in this encoding can be written using Unicode escapes
				# as defined in https://docs.oracle.com/javase/specs/jls/se8/html/jls-3.html#jls-3.3, using the \u prefix.
				# For example, \u002c.
				#
				# * Entries are generally expected to be a single line of the form, one of the following:
				#
				# propertyName=propertyValue
				# propertyName:propertyValue
				#
				# * White space that appears between the property name and property value is ignored,
				# so the following are equivalent:
				#
				# name=Stephen
				# name = Stephen
				#
				# * White space at the beginning of the line is also ignored.
				#
				# * Lines that start with the comment characters ! or # are ignored. Blank lines are also ignored.
				#
				# * The property value is generally terminated by the end of the line. White space following the
				# property value is not ignored, and is treated as part of the property value.
				#
				# * A property value can span several lines if each line is terminated by a backslash (‘\’) character.
				# For example:
				#
				# targetCities=\
				# Detroit,\
				# Chicago,\
				# Los Angeles
				#
				# This is equivalent to targetCities=Detroit,Chicago,Los Angeles (white space at the beginning of lines is ignored).
				#
				# * The characters newline, carriage return, and tab can be inserted with characters \n, \r, and \t, respectively.
				#
				# * The backslash character must be escaped as a double backslash. For example:
				#
				# path=c:\\docs\\doc1
				#
