Bitergia is happy to congratulate the CHAOSS community to its second metrics release. The five working groups of the CHAOSS community defined 39 metrics across 16 focus areas where more than 300 people contributed to the metric definitions.
Let me tell you a story. Once upon a time, an owl asked Bitergia what metrics to use for understanding the software development projects that mattered to them. Every day, the owl would login to the metrics dashboard that Bitergia had provided and try out a different visualization and try to make sense of the data. Then one day, Bitergia with friends from industry, academia, and the Linux Foundation started the CHAOSS (i.e., Community Health Analytics Open Source Software) project to define what metrics existed and how they can be understood. Today, the owl relies on the metrics and visualizations that have been vetted, tested, and standardized by the CHAOSS community, regularly impressing its boss. The owl lived happily ever after and never worried about finding the right metrics again.
This story shows the future we are building with CHAOSS. Born out of the need to serve customers better, Bitergia was a founding member of the CHAOSS project and donated its open source GrimoireLab toolset to the new project. Bitergia continues to employ the maintainers and core developers of the GrimoireLab toolset because it is critical to its business and service offerings.
As the company most vested in the GrimoireLab toolset, Bitergia is proud to support most of the CHAOSS metrics. Bitergia customers already have access through their dashboards. At the bottom of this blog post is a table that shows which metrics are supported by our tool.
The new Bitergia Cauldrio.io platform also supports many of the CHAOSS metrics. Bitergia CEO, Manrique, built a CHAOSS metrics dashboard that any user of Cauldron.io can import and use immediately. The beauty of cauldron.io is that it requires no setup, no installation, and is ready to show metrics with just “one-click” (if you don’t consider the steps required to import the CHAOSS metrics dashboard). For a detailed description on how you can get started with Cauldron.io, see the documentation. See the tweet that shows the metrics from Cauldron.io:
Do you know that software development analytics dashboards created within @cauldronio can be reused or shared with the community to reuse, learn, modify, and even redistribute those modifications? Learn how in our community forum: https://t.co/3VfwNbXDk2 pic.twitter.com/NzW3YtdibZ
