UnitEvent
UnitEvent records something that happened to a Unit — most commonly a function invocation completing. Each event captures the current progress and status of the operation and timing information about when it started and completed.
Events are appended to ConfigHub's event log, which is what event consumers subscribe to in order to react to activity in ConfigHub.
Some fields on UnitEvent — those describing deployment progress and drift against a live system — were written by the bridge mechanism that has since been removed, and no longer have a writer. Configuration now reaches live infrastructure by being published as a Release and pulled by a GitOps operator. For how that operator's status is reported back, see live resources.
