NAME
sysdiagnose -- gathers system-wide diagnostic information helpful in investigating system performance issues. SYNOPSIS
sysdiagnose -h sysdiagnose [-f results_directory] [-t] [-q] [-b] [process_name | pid] DESCRIPTION
sysdiagnose tool gathers system diagnostic information helpful in investigating system performance issues. A great deal of information is harvested, spanning system state and configuration. sysdiagnose needs to be run as root. sysdiagnose can be triggered upon pressing a spe- cial key chord; this is currently Control-Option-Command-Shift-Period. What sysdiagnose Collects: o A spindump of the system o Several seconds of fs_usage ouput o Several seconds of top output o Data about kernel zones o Status of loaded kernel extensions o Resident memory usage of user processes o All system logs, kernel logs, opendirectory log, windowserver log, and log of power management events o A System Profiler report o All spin and crash reports o Disk usage information o I/O Kit registry information o Network status o If a specific process is supplied as an argument: list of malloc-allocated buffers in the process's heap is collected o If a specific process is supplied as an argument: data about unreferenced malloc buffers in the process's memory is collected o If a specific process is supplied as an argument: data about the virtual memory regions allocated in the process OPTIONS
-h Print full usage. -f results_directory Specify the directory where the results will be stored. The default results directory is /var/tmp. -q Skips calling footprint. -t Enable "Thorough Mode". See below. -b Do not show the resulting archive in a Finder window upon completion. process_name | pid If a single process appears to be slowing down the system, passing in the process name or ID as the argument gathers additional process-specific diagnostic data. THOROUGH MODE
sysdiagnose can be run in a "Thorough Mode" in which standard data is gathered as well as a kernel trace. Enabling "Thorough Mode" for the command-line sysdiagnose and key-chord sysdiagnose are independent and are performed as follows: For "Thorough Mode" in the command-line sysdiagnose use the "-t" flag. To enable "Thorough Mode" for special key-chord launches of sysdiagnose execute "touch /var/tmp/.thoroughsysdiagnose" To disable "Thorough Mode" for special key-chord launches of sysdiagnose execute "rm /var/tmp/.thoroughsysdiagnose" Note: Gathering the kernel trace can increase the size of sysdiagnose output by hundreds of MB as well as increase the time for sysdiagnose to com- plete. EXIT STATUS
sysdiagnose 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. Darwin June 2, 2019 Darwin

NAME
sysdiagnose -- gathers system-wide diagnostic information helpful in investigating system performance issues SYNOPSIS
sysdiagnose -h sysdiagnose [-f results_directory] [-A archive_name] [-V volume_path] [-n] [-k] [-F] [-S] [-u] [-Q] [-b] [-p] [-P] [-d] [-D] [-r] [-R] [process_name | pid] DESCRIPTION
The sysdiagnose tool gathers system diagnostic information helpful in investigating system performance issues. A great deal of information is harvested, spanning system state and configuration. The data is stored /var/tmp directory. sysdiagnose needs to be run as root. To cancel an in-flight sysdiagnose triggered via command line interface, press Ctrl-. sysdiagnose is automatically triggered when the following key chord is pressed: Control-Option-Command-Shift-Period. What sysdiagnose collects: o A spindump of the system o Several seconds of fs_usage ouput o Several seconds of top output o Data about kernel zones o Status of loaded kernel extensions o Resident memory usage of user processes o Recent system logs o A System Profiler report o Recent crash reports o Disk usage information o I/O Kit registry information o Network status o If a specific process is supplied as an argument: list of malloc-allocated buffers in the process's heap is collected o If a specific process is supplied as an argument: data about unreferenced malloc buffers in the process's memory is collected o If a specific process is supplied as an argument: data about the virtual memory regions allocated in the process OPTIONS
-h Display help. -v Enable verbose mode to display the container information as it executes. -f results_directory Specify the directory where the results will be stored. The default results directory is /var/tmp. -A archive_name Specify the name of the archive created in the results directory. -V volume_path Specify the root volume for sysdiagnose to run on. -n Do not tar the resulting sysdiagnose directory. -k Do not remove the temporary directory. -F Get feedback data. -S Disable streaming to tarball. -u Disable UI feedback. -Q Skip footprint. -b Do NOT show the resulting archive in a Finder window upon completion. -p Collect only time-sensitive data. Disregards previous -d or -r flags. -P Do not collect time-sensitive data. -d Collect only log data. Disregards previous -p or -r flags. -D Do not collect log data. -r Collect only log archive. Disregards previous -p or -d flags. -R Do not collect log archive. process_name | pid If a single process appears to be slowing down the system, passing in the process name or ID as the argument gathers additional process-specific diagnostic data. Specify only ONE process at a time -- specifying multiple processes is not supported. EXIT STATUS
sysdiagnose 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. OS X
