hotkernel(1m) hotkernel(1m)

hotkernel - sample on-CPU kernel-level functions and modules.

hotkernel [-hm]

This samples the on-CPU function at 1001 Hertz, for a simple yet effective kernel-level profiling tool for sampling exclusive function time. The output will identify which function is on the CPU the most - which is the hottest. See Notes/ALLexclusive_notes.txt for an explanation of exclusive time.

Solaris

stable - Written using Perl and DTrace (Solaris 10 03/05)

Sample kernel functions,
# hotkernel
Sample kernel modules,
# hotkernel -m

See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with verbose descriptions explaining the output.

hotkernel will run until Ctrl-C is hit.
