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

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.
