YAML editor

The YAML tab shows the OpenTelemetry Collector configuration that Telflo generates from the canvas. It is a code editor based on Monaco, with syntax highlighting, line numbers, and find.

How the two views sync

The canvas and the YAML are two views of the same configuration.

• Edit the canvas, and the YAML updates immediately.
• Edit the YAML, and the editor enters manual edit mode. Apply the changes to update the canvas.

In manual edit mode, the other editor tabs are disabled until you finish:

• Apply validates the edited YAML and rebuilds the canvas from it. Apply is available once the YAML is valid.
• Undo All discards the manual edits and leaves manual edit mode.

If a manual edit cannot be parsed or does not validate, the issue is reported in the YAML view so you can correct it before applying. See Validation.

Shortcuts

Export the configuration

• Download YAML configuration in the toolbar saves the configuration as config.yaml.
• Copy in the YAML view copies the YAML to the clipboard.

To run a configuration on collectors, use Fleet management, which keeps collectors in sync automatically instead of requiring a manual file copy.
