WMDE: Metrics & Data Gatherings

Below you will find an internal WMDE presentation covering the general area of WMDE Metric & Data Gatherings from 2016.

This presentation follows on from the initial introduction to engineering analytics activities.

The presentation skims through:

  • WMDE Grafana dashboards
  • The Wikimedia Analytics landscape
  • Grafana & graphite
  • Hadoop, Kafka, Hive & Oozie
  • EventLogging, Mysql replicas & MediaWiki logs
  • Out Analytics scripts
  • How to get access

Interestingly there is an unusual increase in the edit rate 30 minutes after recovery.

I wonder if this is everything that would have happened in the gap?

This is an internal WMDE presentation given at the start of “metric driven development” for the WMDE & Wikidata dev teams.

The presentation is pretty bare bones but it provides a general overview of the plan and links to the current state of things.

The main area of interest from the presentation is the resources slide copied below for convenience.
