# 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

#

# instances as master. The master will perform some periodical tasks that non-masters won't perform.
