Uses DTrace. +.SH SYNOPSIS +.B dispqlen.d +.SH DESCRIPTION +The dispatcher queue length is an indication of CPU saturation. +It is not an indicatior of utilisation - the CPUs may or may not be +utilised when the dispatcher queue reports a length of zero. + +This script measures this activity by sampling at 1000 Hertz per CPU. + +Since this uses DTrace, only the root user or users with the +dtrace_kernel privilege can run this command. +.SH OS +Solaris +.SH STABILITY +unstable - walks private kernel structs. +.SH EXAMPLES +.TP +Print dispatcher queue length by CPU. +# +.B dispqlen.d +.PP +.SH DOCUMENTATION +See the DTraceToolkit for further documentation under the +Docs directory. The DTraceToolkit docs may include full worked +examples with verbose descriptions explaining the output. +.SH EXIT +dispqlen.d will sample until Ctrl-C is hit. +.SH AUTHOR +Brendan Gregg +[Sydney, Australia] +.SH SEE ALSO +uptime(1), dtrace(1M) + |
