Logstash JDBC Input Plugin

This is a plugin for Logstash.

It is fully free and fully open source. The license is Apache 2.0, meaning you are pretty much free to use it however you want in whatever way.

JDBC Input Plugin Has Moved

This JDBC Input Plugin is now a part of the JDBC Integration Plugin; this project remains open for backports of fixes from that project to the 5.x series where possible, but issues should first be filed on the integration plugin.


Logstash provides infrastructure to automatically generate documentation for this plugin. We use the asciidoc format to write documentation so any comments in the source code will be first converted into asciidoc and then into html. All plugin documentation are placed under one central location.

1. Plugin Developement and Testing


  • To get started, you'll need JRuby with the Bundler gem installed.

  • Create a new plugin or clone and existing from the GitHub logstash-plugins organization.

  • Install dependencies

bundle install


bundle exec rspec

The Logstash code required to run the tests/specs is specified in the Gemfile by the line similar to:

gem "logstash", :github => "elasticsearch/logstash", :branch => "1.5"

To test against another version or a local Logstash, edit the Gemfile to specify an alternative location, for example:

gem "logstash", :github => "elasticsearch/logstash", :ref => "master"
gem "logstash", :path => "/your/local/logstash"

Then update your dependencies and run your tests:

bundle install
bundle exec rspec

2. Running your unpublished Plugin in Logstash

2.1 Run in a local Logstash clone

  • Edit Logstash tools/Gemfile and add the local plugin path, for example:
gem "logstash-input-jdbc", :path => "/your/local/logstash-input-jdbc"
  • Update Logstash dependencies
rake vendor:gems
  • Run Logstash with your plugin
bin/logstash -e 'input {jdbc {..}}'

At this point any modifications to the plugin code will be applied to this local Logstash setup. After modifying the plugin, simply rerun Logstash.

2.2 Run in an installed Logstash

  • Build your plugin gem
gem build logstash-input-jdbc.gemspec
  • Install the plugin from the Logstash home
bin/plugin install /your/local/plugin/logstash-input-jdbc.gem
  • Start Logstash and proceed to test the plugin

Example configuration

Reading data from MySQL:

input {
  jdbc {
    jdbc_driver_library => "/path/to/mysql-connector-java-5.1.33-bin.jar"
    jdbc_driver_class => "com.mysql.jdbc.Driver"
    jdbc_connection_string => "jdbc:mysql://host:port/database"
    jdbc_user => "user"
    jdbc_password => "password"
  # or jdbc_password_filepath => "/path/to/my/password_file"
    statement => "SELECT ..."
    jdbc_paging_enabled => "true"
    jdbc_page_size => "50000"

filter {
  [some filters here]

output {
  stdout {
    codec => rubydebug
  elasticsearch_http {
    host => "host"
    index => "myindex"


All contributions are welcome: ideas, patches, documentation, bug reports, complaints, and even something you drew up on a napkin.

Programming is not a required skill. Whatever you've seen about open source and maintainers or community members saying "send patches or die" - you will not see that here.

It is more important to me that you are able to contribute.

For more information about contributing, see the CONTRIBUTING file.

You can’t perform that action at this time.
