A Public ElasticSearch Cluster with Bugzilla Data


Provide the public with an easy-to-query historical view of Bugzilla bugs.


The BMO/ES cluster is important for managing many of Mozilla's projects: It is the underlying active data system that is used by a multitude of dashboards to track various project metrics. It is capable of providing both high level aggregates over the million+ issues, providing detailed historical views into those issues, and it provides that information fast.

Let's Use It!

BMO/ES is a service, which means you can use it right now! You probably already have your browser open, so lets send it queries:


Minimum required to hit ES cluster on Github
Minimum required to pull comments on Github
Simple Bug Count on Github
Can you reach the private cluster? on Github

Basic walk-through
