Elasticsearch Ecosystem

Here's some more information about what is happening in the ecosystem we are maintaining around the ELK stack - that's Elasticsearch plus Logstash and Kibana - including plugin and driver releases.

Slides & Videos

This week, we're bringing you a whole whack of Elasticsearch love from last week's DrupalCon Amsterdam! Not a Drupalista? No problem - these videos are great for all lovers of things PHP and folks interested in learning how to scale the ELK stack for centralized logging and monitoring.

Nikolay Ignatov and Welin Welchev on Elasticsearch as the new school search engine for the Drupal Content Management System

Steven Merrill on using a fully open source stack for logging and monitoring of (Think billions of logs.)

Larry Garfield and Hagen Last on using Elasticsearch as a key component for building a decoupled Content Management System

Where to find Us

We'd love to feature all the great Elasticsearch, Logstash, and Kibana presentations and meetups happening worldwide in this section. If you're speaking or hosting a meetup, let our Director of Developer Relations, Leslie Hawthorn, know!


We're a proud sponsor of the 5th anniversary of DevOps Days Belgium, held in its original hometown of Ghent. Elasticsearch will have a booth at the conference, so stop by and say hello to Leslie Hawthorn and Alan Hardy between sessions. We'll be at DevOps Days October 27-28th.


Zeng Yong, aka Medcl, is one of our most active community members in China. He has two upcoming talks on all things Elasticsearch:

Medcl is also busy convening the 3rd annual Elasticsearch Users Conference in China for October 25th. You can find out more information about the event and register on



The code.talks conference is back in Hamburg this year on October 9th and 10th, though with a new name. (We had a great time there last year when this conference was known simply as Developer Conference EU.) Alexander Reelsen will be speaking once again, along with Isabel Drost-Fromm.

Where to Find You

Our Director of Developer Relations, Leslie Hawthorn, is hard at work to help folks create more Elasticsearch meetup groups and to help meetup organizers find more speakers. If you are interested in either effort, let her know.

Oh yeah, we're also hiring. If you'd like us to find you for employment purposes, just drop us a note.  We care more about your skill set and passion for Elasticsearch, Kibana, and Logstash than where you rest your head.
