Get Involved

There is a lot to do! If you are interested in getting involved, please join the mailing lists and attend the community meetings. If you're interested in contributing to a specific part of the project, please join the appropriate special interest group (SIG). Details for all of these items are below. We are a friendly, collaborative group and look forward to working together!

Governing Bodies

Both committees meet regularly, and the respective meeting notes are publicly available in the GC meeting notes and the TC meeting notes Google Docs. The Governance Committee meetings are also recorded. If you want to check out the recordings, head to the meeting recordings.

Areas of Interest

Technical committee members, maintainers, and approvers are encouraged to list their areas of interest in this document to help community members find interested parties and form new special interest groups.

Communication

Discussions

We use GitHub discussions for most communications. Please join us there!

For those who are brand new to OpenTelemetry and want to chat or get redirected to the appropriate place for a specific question, feel free to join the CNCF OpenTelemetry Slack channel. If you are new, you can create a CNCF Slack account here.

Calendar

The shared community calendar contains all public OpenTelemetry meetings, including weekly SIG meetings, monthly community meetings, etc. You can access it via:

The best way to subscribe to specific OpenTelemetry meeting series is to join the associated calendar-...@opentelemetry.io meeting invite groups below. This will invite you to the specific OpenTelemetry meetings, correctly block time for accepted meetings, and keep your calendar in sync with new and updated events.

Alternatively, if you wish to subscribe to all OpenTelemetry meeting series you can subscribe to calendar-all@opentelemetry.io.

How to

Special Interest Groups

We organize the community into Special Interest Groups (SIGs) to improve our workflow and more efficiently manage a community project. While meetings are expected to happen regularly, they are subject to contributors' availability and may be rescheduled or changed at time. Check our public calendar and SIG-specific GitHub discussions for meeting changes and cancellations. All meetings happen over Zoom, have a meeting notes document, and are recorded and available on Zoom cloud.

Please do not hesitate to contact SIG owners if the proposed time of the meeting or tools used is unavailable for you. For instance, it is a good practice to alternate morning/evening meetings once SIG has representatives from 3 largely distinct timezones. The best way to report it and suggest an alternative is to file an issue on this repository or discuss it in SIG-specific GitHub discussions.

[!NOTE] The meeting times in the tables below are given in 24-hour notation. All meeting hours between 2pm and 1am UTC are in Pacific Time (PT), with Daylight Saving Time. All meeting hours between 2am and 1pm UTC in UTC+8, without Daylight Saving Time.
