The tmdiagnose tool gathers system and
backup information in order to assist Apple when investigating issues
related to Time Machine. A great deal of information is harvested, spanning
system state, system and backup configuration, and snapshot details.
- A spindump of the system
- Several seconds of fs_usage ouput
- Several seconds of top output
- Individual samples of backupd and Finder
- Power Management state and logs
- IOKit registry information
- A netstat inspection
- A list of all open files on the system
- All system logs
- All kernel logs
- All install logs
- All fsck_hfs logs
- All WiFi logs
- Disk Utility logs for all local users
- The system migration log
- All spin and crash reports for the following processes:
- backupd
- mds
- diskimages-helper
- DesktopServicesHelper
- newfs_hfs
- NetAuthSysAgent
- Recent spin and crash reports for the following processes, for all local
users:
- Finder
- Locum
- System Settings
- SystemUIServer
- iPhoto
- Mail
- MailTimeMachineHelper
- Address Book
- Basic information about reachable AirPort and Time Capsule devices
- The FindSystemFiles cache
- Information about disks and mounted network shares
- Information about attached disk images
- A System Profiler report
- A list of software that has been installed via the
darwinup
tool
- Time Machine preferences, caches, and configuration information
- Comprehensive information about Time Machine backups and snapshots
The high-level backup structure for the current machine directory
is recreated inside the diagnostic bundle, including the capture of various
Time Machine log files contained within snapshots. Items in this
"skeleton" structure have on them the extended attributes of the
originals. Recreations of local snapshots are also captured in the same
manner.
The tmdiagnose tool will
run the Spotlight diagnostic tool
mddiagnose
automatically, if it is available.
- No user files are harvested from within backups
- No authentication credentials are harvested from the system
- No authentication credentials are harvested for reachable AirPort and Time
Capsule devices
-h- Print full usage.
-d
sec- Delay the start of the diagnostic by sec seconds.
The system alert sound will play two times when the diagnostic
begins.
-f
path- Write the diagnostic to the specified path.
-m- Gather memory diagnostics for backupd and Finder.
-r- Do not reveal the diagnostic in Finder when finished.
tmdiagnose exits with status 0 if there
were no internal errors encountered during the diagnostic, or >0 when an
error unrelated to external state occurs or unusable input is provided by
the user.
