type: boolean

description: |
True if we failed to register with the idle service. Absent otherwise.
Means IPC probably isn't working well.
Child-process data will likely be absent, or incomplete.

Counts the number of times init had to be called during shutdown.
Should never have a value for any session long enough to grow idle.

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.
