Configuration won't validate

Red border on a node — an error. Processors need both an input and an output; receivers need an outgoing edge; exporters need an incoming edge; extensions must not be connected. See Validation.
Schema error on a field — the value isn't valid for the selected collector version. Correct the value, or change the collector version in the toolbar.
Open the validation panel to see every issue with the affected node and a description.

The canvas and YAML sync both ways. If a manual YAML edit can't be parsed, the canvas can't rebuild from it — fix the syntax error flagged in the YAML view.
Check the validation panel for the specific problem.

Undo/Redo is session-only and clears when you close the editor. Use Save to record a version you want to keep.
If you edited a read-only version, Telflo prompts you to save your changes as a new version — make sure you did.

Runs that can't be started (testing service unavailable, rate-limited, or you're offline) are marked Error rather than left hanging.
Make sure a saved version is loaded and an organization is selected.
For pipelines with long windows (batch, tail_sampling), increase the run duration so output has time to emerge. See Running tests.
If you're warned about a fixture mismatch, your sample file's shape may not match the selected signal type — pick the right pipeline or a matching file.

Pending pickup / Applying usually resolves on the next heartbeat — give it a cycle.
Apply failed means the collector rejected the config. Re-validate and test it, check the collector's logs, then publish and assign a corrected version. See Update the config.
Stale means no recent heartbeat (over 15 minutes). Check the host and the collector process; it will catch up when it reconnects.
If a collector can't authenticate at all, its install token may have expired or been revoked — reinstall with a current token. See Tokens & security.

Confirm you installed with the bundle for this fleet (it embeds the correct endpoint and token).
Newly installed collectors usually appear within a minute; if not, check the host's network egress to Telflo and the collector/supervisor logs.

AI tab: enable AI in Settings → AI; request access if prompted. See AI access.
Testing tab: it appears when testing is enabled for your editor session.

Member and organization management requires the Admin role. Contributors can build configurations but not manage the org. See Members & roles.
