Update the configuration

Rolling out a change follows the same loop as building: edit, test, publish. You then assign the new version to the fleet, and collectors apply it on their next check-in.

Roll out a new version

1. Edit the configuration in the editor and test it.
2. Publish the new version.
3. Assign the published version to the fleet.
4. Track the fleet's detail page. Instances move from Pending pickup to Applying to In sync as they receive and apply the version.

Collectors pull from Telflo, so you do not change anything on the hosts. The rollout happens over OpAMP.

Roll back

To roll back, assign an earlier published version to the fleet. Instances converge on it the same way and report In sync once applied. Version notes make it easier to choose the rollback target. See Versions & publishing.

If an apply fails

An instance that reports Apply failed rejected the configuration.

1. Open the configuration, then validate and test it.
2. Check the collector's logs on the host for the reason.
3. Publish a corrected version and assign it to the fleet.
