############################ # 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 # # If you are running more than one instances of Graylog server you have to select one of these # instances as master. The master will perform some periodical tasks that non-masters won't perform. is_master = true # The auto-generated node ID will be stored in this file and read after restarts.
