NAME

tpfmt — format tprof samples

SYNOPSIS

tpfmt

[-CkLPs] [-p pid]

DESCRIPTION

The tpfmt utility creates and outputs a plain text representation for a given profiling result recorded by tprof(8).

The tpfmt utility accepts the following options.

-C

Don't distinguish CPUs. All samples are treated as its CPU number is 0.

-k

Kernel only. Ignore samples for userland code.

-L

Don't distinguish LWPs. All samples are treated as its LWP ID is 0.

-P

Don't distinguish processes. All samples are treated as its PID is 0.

-p pid

Process only samples for the process with PID pid and ignore the rest.

-s

Per symbol. Try to aggregate samples by functions rather than instructions. It's currently useful only for in-kernel samples.

EXAMPLES

See tprof(8) for an example.
