YAML editor

The YAML view shows the OpenTelemetry Collector configuration Telflo generates from your canvas. It's a full code editor (powered by Monaco, the editor behind VS Code) with syntax highlighting, line numbers, and find.

Two-way sync

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

Visual canvas  ⇄  Generated YAML

• Edit the canvas → the YAML updates automatically.
• Edit the YAML → the canvas updates to match.

This means you can work however you prefer — drag-and-drop for structure, then drop into YAML for fine-grained tweaks — without the two drifting apart.

If a manual YAML edit can't be parsed, the canvas can't rebuild from it. Validation surfaces the problem so you can fix the syntax — see Validation.

Exporting the configuration

From the toolbar you can get the YAML out of Telflo:

• Download YAML — saves the configuration as a config.yaml file.
• Copy — copy the YAML to your clipboard to paste elsewhere.

For running this config on real collectors, prefer the Deployment flow, which keeps collectors in sync automatically rather than requiring a manual file copy.

• Save and publish your work in Versions & publishing.
