stacksize.d - measure stack size for running threads. Uses DTrace. stacksize.d This samples the user stack size by process name, and prints a distribution plot so that the average stack size can be easily identified. Since this uses DTrace, only the root user or users with the dtrace_kernel privilege can run this command. Solaris stable - needs the sched provider.

This samples until Ctrl-C is hit. # stacksize.d

value size of the user stack

count number of samples at this size

See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with verbose descriptions explaining the output. stacksize.d will sample until Ctrl-C is hit. Jonathan Adams pmap(1), dtrace(1M)
