Today we are very excited to release our Project Journey Report for Prometheus. This is the third report we have issued for CNCF graduated projects following reports for Kubernetes and Envoy.

Prometheus is a widely-adopted open source metrics-based monitoring and alerting system. When Prometheus joined CNCF in May 2016, the foundation started promotional efforts to help sustain, nurture, and expand the Prometheus community. These efforts have included blog posts, email newsletter mentions, social media support, CNCF-hosted webinars, and end-user case studies.

Today, Prometheus is kicking off its fourth PromCon in Germany, which is sold out with more than 200 attendees. CNCF has helped administer the events in 2017, 2018, and 2019, and is working with the Prometheus maintainers to plan how the event should expand in the future including adding an event in North America.

This report attempts to objectively assess the state of the Prometheus project and how CNCF has impacted the progress and growth of Prometheus. For the report, we pulled data from multiple sources, particularly CNCF’s own DevStats tool, which provides detailed development statistics for all CNCF projects.

Some of the highlights of the report include:

  • Code Contributions – The total number of companies contributing code has increased by 258% since Prometheus joined CNCF, from 202 to 723.
Cumulative growth of contributions by company since Prometheus project launch (Q1 2014 – Q3 2019)
  • Development Velocity – Prometheus has enjoyed an 825% expansion of individual contributors over the three years since the project joined CNCF.
Cumulative growth in commits by quarter (Q1 2014 – Q3 2019)
  • Documentation – The number of documentation commits has increased by 241% since Prometheus joined CNCF.
Growth in participation in Prometheus project documentation (Q1 2014 – Q3 2019)

Since joining CNCF in 2016, Prometheus has recorded:

  • >6.3 K contributors
  • >13.5 K code commits
  • >7.2 K pull requests
  • >113 K contributions
  • 723 contributing companies

Prometheus is growing quickly – in fact, it is among the top three CNCF projects in terms of velocity. As we continue to collaborate with the project maintainers, we only expect this rapid growth to continue.

This report is part of CNCF’s commitment to fostering and sustaining an ecosystem of open source, vendor-neutral projects. Please read and enjoy the report, share your feedback with us – and stay tuned for more project journey reports for other projects.
