    Description

      As discussed in the call, when an application first starts to run, its corresponding TimelineCollector instance may not be up yet, or if the TimelineCollector goes down when node manager dies (TimelineCollector now runs as part of NM auxiliary services), the timeline client
      will not able to write entities. We need to address or mitigate the issue if possible, or at least call it out.
