  flush_failures:
    type: counter
    description: |
      The number of times we failed to flush all non-parent-process data,
      throwing even partial results into the trash.
      If this number is high, we might consider writing custom `MozPromise`-
      handling code instead of using `MozPromise::All`.

  shutdown_registration_failures:
    type: counter
    description: |
      The number of times we tried to register shutdown flush routines for
      content child processes, and failed (probably because there was no main
      thread).
      As a result there may be data loss from content child processes.
      Large or rising number of clients experiencing this indicates we should
      perhaps refactor content child shutdown in FOG to try harder to register
      flush operations.
      Will likely be obsoleted by bug 1641989.
