kstat_types.d(1m)

NAME
kstat_types.d - Trace kstat reads with type info. Uses DTrace.

SYNOPSIS
kstat_types.d

DESCRIPTION
kstat is the Kernel Statistics framework, which is used by tools such as vmstat, iostat, mpstat and sar. Try running vmstat while kstat_types.d is tracing - you should see details of the kstat reads performed. Since this uses DTrace, only the root user or users with the dtrace_kernel privilege can run this command.

    # kstat_types.d
