Starting with version 1.3.10, OctoPrint comes with a built-in plugin “Anonymous Usage Tracking” that performs anonymous usage tracking. Tracking will only take place if the plugin is enabled and you’ve decided to opt-in during initial setup (or enabled it manually afterwards, through the corresponding switch in the settings).

What data gets recorded?

All tracking requests record the OctoPrint version and a unique identifier of the OctoPrint instance (randomly created on first start and not connected in any way to personal identifiable information) to allow counting of unique instances per version. Additionally a rough location from which the request originates will be determined based on the client IP using the GeoLite2 City database and GeoIP. The client IP address itself will not be tracked.

The plugin fires tracking requests for the following events. Version numbers indicate in which OctoPrint version after 1.3.10rc1 an event or additional data was added, also for as of yet unreleased versions. Most of the events can be switched off in the settings.

  • Regular ping every 15min

    • Uptime of OctoPrint 1.3.11rc1+

How and where does this data get evaluated? Are there any third parties involved?

The data gets recorded and evaluated on tracking.octoprint.org. It doesn’t leave that server and gets evaluated in place through a local ELK stack and Grafana install.

No third parties do have access to the raw data. Visualizations based on this data might be shared with the public in the future to give a general overview over version distribution and similar metrics.

How can I disable tracking?

Open your OctoPrint settings, click on “Anonymous Usage Tracking”, uncheck the box that says “Enable Anonymous Usage Tracking” and save.

Where can I find the source of this plugin?

You can find the source code of the tracking plugin built into OctoPrint in src/octoprint/plugins/tracking of the OctoPrint source code.
