Start processing data recordings with your Foxglove Agent.

Adding recording files

Move your completed recordings into the data directory. The Agent will be notified by the filesystem when a new recording is available.

The Agent receives filesystem notifications when files are created in the data directory. This notification is triggered when a file is created. To avoid triggering notifications on incomplete files, data files should be renamed into the data directory after writing (use mv rather than cp). Alternatively, you can write files into the data directory with an ignored filename suffix, and then rename it to remove the suffix after writing. You can configure recording filters to control which files are treated as recordings.

Note: it is possible to write MCAP files directly into the watched directory. The Agent will ignore notifications for any MCAP file which does not contain trailing magic bytes, under the assumption that the file is still being written to. The agent scans the watched directory periodically for missed files, and will add the completed file then.

Note: The ROS 1 bag writer uses an .active suffix on incomplete files by default, and can be used to write directly into the data directory.

Import to cloud

Recordings for your device will initially appear in the Recordings page. In order to visualize and download this data, you can select these recordings and click "Import". Once the import status is displayed as "complete", the recording is available. You can also do this with the Recordings API.

Automatically import recording files

The Agent can be configured to automatically upload recording files that match a configured glob pattern. Set the WATCH_AUTO_IMPORT_PATTERN variable in /etc/foxglove/agent/envfile to a valid glob pattern to enable this functionality. This pattern supports * and ? wildcards.

For example, the following configuration in /etc/foxglove/agent/envfile will cause MCAP files in the auto_import/ subdirectory of STORAGE_ROOT to be imported as soon as they are created:

WATCH_AUTO_IMPORT_PATTERN="auto_import/*.mcap"

Delete recording files

You can delete recording files as needed to manage disk space on your device. Files that were imported will remain available in Foxglove after the original is deleted. Files that were not imported before deletion will no longer appear in the Recordings page.
