drupal_dblog

Milestone: 1

This is a community-contributed plugin! It does not ship with logstash by default, but it is easy to install! To use this, you must have installed the contrib plugins package.

Retrieve watchdog log events from a Drupal installation with DBLog enabled. The events are pulled out directly from the database. The original events are not deleted, and on every consecutive run only new events are pulled.

The last watchdog event id that was processed is stored in the Drupal variable table with the name “logstash_last_wid”. Delete this variable or set it to 0 if you want to re-import all events.

More info on DBLog: http://drupal.org/documentation/modules/dblog

Details

add_field

  • Value type is hash
  • Default value is {}

Add a field to an event

add_usernames

  • Value type is boolean
  • Default value is false

By default, the event only contains the current user id as a field. If you whish to add the username as an additional field, set this to true.

bulksize

  • Value type is number
  • Default value is 5000

The amount of log messages that should be fetched with each query. Bulk fetching is done to prevent querying huge data sets when lots of messages are in the database.

  • There is no default value for this setting.

The character encoding used in this input. Examples include “UTF-8” and “cp1252”

This setting is useful if your log files are in Latin-1 (aka cp1252) or in another character set other than UTF-8.

This only affects “plain” format logs since json is UTF-8 already.

codec

  • Value type is codec
  • Default value is "plain"

The codec used for input data. Input codecs are a convenient method for decoding your data before it enters the input, without needing a separate filter in your Logstash pipeline.

databases

  • Value type is hash
  • There is no default value for this setting.

Specify all drupal databases that you whish to import from. This can be as many as you whish. The format is a hash, with a unique site name as the key, and a databse url as the value.

Example: [ “site1”, “mysql://user1:password@host1.com/databasename”, “other_site”, “mysql://user2:password@otherhost.com/databasename”, … ]

debug DEPRECATED

  • DEPRECATED WARNING: This config item is deprecated. It may be removed in a further version.
  • Value type is boolean
  • Default value is false

format DEPRECATED

  • DEPRECATED WARNING: This config item is deprecated. It may be removed in a further version.
  • Value can be any of: "plain", "json", "json_event", "msgpack_event"
  • There is no default value for this setting.

The format of input data (plain, json, json_event)

interval

  • Value type is number
  • Default value is 10

Time between checks in minutes.

message_format DEPRECATED

  • DEPRECATED WARNING: This config item is deprecated. It may be removed in a further version.
  • Value type is string
  • There is no default value for this setting.

If format is “json”, an event sprintf string to build what the display @message should be given (defaults to the raw JSON). sprintf format strings look like %{fieldname}

If format is “json_event”, ALL fields except for @type are expected to be present. Not receiving all fields will cause unexpected results.

tags

  • Value type is array
  • There is no default value for this setting.

Add any number of arbitrary tags to your event.

This can help with processing later.

type

  • Value type is string
  • Default value is "watchdog"

Label this input with a type. Types are used mainly for filter activation.

If you create an input with type “foobar”, then only filters which also have type “foobar” will act on them.

The type is also stored as part of the event itself, so you can also use the type to search for in the web interface.
