  2. # GRAYLOG CONFIGURATION FILE
  3. ############################
  4. #
  5. # This is the Graylog configuration file. The file has to use ISO 8859-1/Latin-1 character encoding.
  6. # Characters that cannot be directly represented in this encoding can be written using Unicode escapes
  7. # as defined in https://docs.oracle.com/javase/specs/jls/se8/html/jls-3.html#jls-3.3, using the \u prefix.
  8. # For example, \u002c.
  9. #
  10. # * Entries are generally expected to be a single line of the form, one of the following:
  11. #
  12. # propertyName=propertyValue
  13. # propertyName:propertyValue
  14. #
  15. # * White space that appears between the property name and property value is ignored,
  16. # so the following are equivalent:
  17. #
  18. # name=Stephen
  19. # name = Stephen
  20. #
  21. # * White space at the beginning of the line is also ignored.
  22. #
  23. # * Lines that start with the comment characters ! or # are ignored. Blank lines are also ignored.
  24. #
  25. # * The property value is generally terminated by the end of the line. White space following the
  26. # property value is not ignored, and is treated as part of the property value.
  27. #
  28. # * A property value can span several lines if each line is terminated by a backslash (‘\’) character.
  29. # For example:
  30. #
  31. # targetCities=\
  32. # Detroit,\
  33. # Chicago,\
  34. # Los Angeles
  35. #
  36. # This is equivalent to targetCities=Detroit,Chicago,Los Angeles (white space at the beginning of lines is ignored).
  37. #
  38. # * The characters newline, carriage return, and tab can be inserted with characters \n, \r, and \t, respectively.
  39. #
  40. # * The backslash character must be escaped as a double backslash. For example:
  41. #
  42. # path=c:\\docs\\doc1
  43. #
  44. # If you are running more than one instances of Graylog server you have to select one of these
  45. # instances as master. The master will perform some periodical tasks that non-masters won't perform.

  51. # Generate one by using for example: pwgen -N 1 -s 96
  52. # ATTENTION: This value must be the same on all Graylog nodes in the cluster.
  53. # Changing this value after installation will render all user sessions and encrypted values in the database invalid. (e.g. encrypted access tokens)
  54. password_secret = {{ graylog_config['password_secret'] }}
  55. # The default root user is named 'admin'
  56. root_username = {{ graylog_config['root_username'] }}

  58. # system and in case you lose connectivity to your authentication backend)
  59. # This password cannot be changed using the API or via the web interface. If you need to change it,
  60. # modify it in this file.
  61. # Create one by using for example: echo -n yourpassword | shasum -a 256
  62. # and put the resulting hash value into the following line
  63. root_password_sha2 = {{ graylog_config['root_password_sha2'] }}
  64. # The email address of the root user.
  65. # Default is empty
  66. #root_email = ""

  113. #
  114. # The external Graylog URI usually has to be specified, if Graylog is running behind a reverse proxy or load-balancer
  115. # and it will be used to generate URLs addressing entities in the Graylog REST API (see $http_bind_address).
  116. #
  117. # When using Graylog Collector, this URI will be used to receive heartbeat messages and must be accessible for all collectors.
