sampleproc - sample processes on the CPUs. Uses DTrace. sampleproc [hertz] This program samples which process is on each CPU, at a particular configurable rate. This can be used as an estimate for which process is consuming the most CPU time. Since this uses DTrace, only the root user or users with the dtrace_kernel privilege can run this command. Solaris unstable - uses the ncpus_online kernel symbol.
