intbycpu.d - interrupts by CPU. Uses DTrace. intbycpu.d intbycpu.d is based on a DTrace OneLiner to a report of the number of interrupts by CPU. The intrstat(1M) command can be used for further analysis of interrputs. Docs/oneliners.txt and Docs/Examples/oneliners_examples.txt in the DTraceToolkit contain this as a oneliner that can be cut-n-paste to run. Since this uses DTrace, only the root user or users with the dtrace_kernel privilege can run this command. Solaris stable - needs the sdt provider interrupt probes.

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

CPU This is the CPU id.

INTERRUPTS This is the number of interrputs received in the sample.

See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with verbose descriptions explaining the output. intbycpu.d will sample until Ctrl-C is hit. Brendan Gregg [Sydney, Australia] intrstat(1M), dtrace(1M)
