spindump(8) BSD System Manager's Manual spindump(8)
NAME
spindump -- Profile entire system during a time interval
SYNOPSIS
spindump [pid | partial-name [duration [interval]]] [-file path] [-wait]
[-findDsyms] [-delayOnSignal seconds]
DESCRIPTION
spindump is used by various system components to create reports when an
unresponsive application is force quit. Reports are stored at:
/Library/Logs/DiagnosticReports/
For normal application force quits spindump will display a dialog to
offer the choice to view more details and/or send a report to Apple.
-------------------------------------
When run manually, spindump samples user and kernel stacks for every
process in the system.
The process with the matching pid or partial-name will be sorted topmost
in the report, if specified. "-notarget" may be used to avoid providing a
target process when specifying a duration and interval.
duration is the duration of the sampling in seconds. If not specified,
the default of 10 seconds is used.
interval is the number of miliseconds between samples. If not specified,
the default of 10 miliseconds is used.
The -file argument specifies where the report should be written. If path
is a file, it will be overwritten. If path is a directory, a file will be
created inside that directory with the name following the format <app-
name>_<pid>.spindump.txt. If a file by that name already exists, spindump
will add a unique number to the filename. If not specified, spindump will
output reports to files inside /tmp.
The -wait flag tells spindump to wait for the process to exist before
sampling. If the process already exists, spindump will begin sampling
immediately.
The -findDsyms flag tells spindump to use spotlight to find dsyms for use
during symbolication.
The -delayOnSignal argument tells spindump to wait seconds seconds after
receiving a signal before exiting.
