A read-only CwrCollectionStatus reporting whether this timeline capture is in progress, captured, or stopped. Like its histogram counterpart, parameters cannot be modified mid-capture, so a management tool checks this before attempting reconfiguration or before trying to read the completed data. For example, a polling script waits for cwrTlStatus to read statusCaptured before pulling rows from cwrTlDataTable, ensuring it does not read a partially filled timeline.
