data_directory_info:
type: object
description: |
Information about the data directories and files used by FOG.
Structure is an array of objects, each containing the following properties:
- `dir_name`: The name of the directory. This is the subdirectory name relative to the
FOG data directory and should only include "db", "events", and "pending_pings".
- `dir_exists`: Whether the directory exists. This should only be false on the first
run of FOG, or if the directory was deleted.
- `dir_created`: The creation time of the directory, in seconds since the unix epoch. If
the directory does not exist, this will be `null` and if the time cannot be determined,
it will default to `0`.
- `dir_modified`: The last modification time of the directory, in seconds since the unix
epoch. If the directory does not exist, this will be `null` and if the time cannot be
determined, it will default to `0`.
- `file_count`: The number of files in the directory. If the directory does not exist,
this will be `0`.
- `files`: An array of objects, each containing:
- `file_name`: The name of the file. Could be `data.safe.bin`, `events.safe.bin`, or
A uuid representing the doc-id of a pending ping.
- `file_created`: The creation time of the file, in seconds since the epoch. If the
file does not exist, this will be `null` and if the time cannot be determined, it
will default to `0`.
- `file_modified`: The last modification time of the file, in seconds since the epoch.
If the file does not exist, this will be `null` and if the time cannot be determined,
it will default to `0`.
- `file_size`: The size of the file in bytes. This can be just about any size but a
`0` value indicates the file is empty.

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.
