jdbc

Add a field to an event

The character encoding of all columns, leave empty if the columns are already properly UTF-8 encoded. Specific columns charsets using :columns_charset can override this setting.

Whether the previous run state should be preserved

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.

The character encoding for specific columns. This option will override the :charset option for the specified columns.

Example:

input {
  jdbc {
    ...
    columns_charset => { "column0" => "ISO-8859-1" }
    ...
  }
}

This will only convert column0 that has ISO-8859-1 as an original encoding.

Maximum number of times to try connecting to database

Number of seconds to sleep between connection attempts

Disable or enable metric logging for this specific plugin instance by default we record all the metrics we can, but you can disable metrics collection for a specific plugin.

Add a unique ID to the plugin configuration. If no ID is specified, Logstash will generate one. It is strongly recommended to set this ID in your configuration. This is particularly useful when you have two or more plugins of the same type, for example, if you have 2 grok filters. Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.

output {
 stdout {
   id => "my_plugin_id"
 }
}

JDBC connection string

Timezone conversion. SQL does not allow for timezone data in timestamp fields. This plugin will automatically convert your SQL timestamp fields to Logstash timestamps, in relative UTC time in ISO8601 format.

Using this setting will manually assign a specified timezone offset, instead of using the timezone setting of the local machine. You must use a canonical timezone, America/Denver, for example.

JDBC driver class to load, for exmaple, "org.apache.derby.jdbc.ClientDriver" NB per https://github.com/logstash-plugins/logstash-input-jdbc/issues/43 if you are using the Oracle JDBC driver (ojdbc6.jar) the correct jdbc_driver_class is "Java::oracle.jdbc.driver.OracleDriver"

Tentative of abstracting JDBC logic to a mixin for potential reuse in other plugins (input/output) This method is called when someone includes this module Add these methods to the base given. JDBC driver library path to third party driver library. In case of multiple libraries being required you can pass them separated by a comma.

If not provided, Plugin will look for the driver class in the Logstash Java classpath.

JDBC fetch size. if not provided, respective driver’s default will be used

JDBC page size

JDBC enable paging

This will cause a sql statement to be broken up into multiple queries. Each query will use limits and offsets to collectively retrieve the full result-set. The limit size is set with jdbc_page_size.

Be aware that ordering is not guaranteed between queries.

JDBC password

JDBC password filename

Connection pool configuration. The amount of seconds to wait to acquire a connection before raising a PoolTimeoutError (default 5)

JDBC user

Connection pool configuration. Validate connection before use.

Connection pool configuration. How often to validate a connection (in seconds)

Path to file with last run time

Whether to force the lowercasing of identifier fields

Hash of query parameter, for example { "target_id" => "321" }

Whether to save state or not in last_run_metadata_path

Schedule of when to periodically run statement, in Cron format for example: "* * * * *" (execute query every minute, on the minute)

There is no schedule by default. If no schedule is given, then the statement is run exactly once.

General/Vendor-specific Sequel configuration options.

An example of an optional connection pool configuration max_connections - The maximum number of connections the connection pool

examples of vendor-specific options can be found in this documentation page: https://github.com/jeremyevans/sequel/blob/master/doc/opening_databases.rdoc

Log level at which to log SQL queries, the accepted values are the common ones fatal, error, warn, info and debug. The default value is info.

If undefined, Logstash will complain, even if codec is unused. Statement to execute

To use parameters, use named parameter syntax. For example:

"SELECT * FROM MYTABLE WHERE id = :target_id"

here, :target_id is a named parameter. You can configure named parameters with the parameters setting.

Path of file containing statement to execute

Add any number of arbitrary tags to your event.

This can help with processing later.

If tracking column value rather than timestamp, the column whose value is to be tracked

Type of tracking column. Currently only "numeric" and "timestamp"

This is the base class for Logstash inputs. Add a type field to all events handled by this input.

Types are used mainly for filter activation.

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

If you try to set a type on an event that already has one (for example when you send an event from a shipper to an indexer) then a new input will not override the existing type. A type set at the shipper stays with that event for its life even when sent to another Logstash server.

Use an incremental column value rather than a timestamp
