Fsdb::Filter::kitrace_to_db

NAME

kitrace_to_db - convert kitrace output to Fsdb format

SYNOPSIS

kitrace_to_db [-Y year] [registers] <kitrace.out >kitrace.fsdb

DESCRIPTION

Converts a kitrace data stream to Fsdb format.

Optional arguments list registers which will be picked out of the output stream and formatted as their own columns.

OPTIONS

-Y Y or --year Y

Specify the 4-digit year for the dataset (defaults to current year).

-u or --utc

Specify UTC timezone (defaults to local time zeon).

This module also supports the standard fsdb options:

-i or --input InputSource

Read from InputSource, typically a file name, or "-" for standard input, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.

-o or --output OutputDestination

Write to OutputDestination, typically a file name, or "-" for standard output, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.

--autorun or --noautorun

By default, programs process automatically, but Fsdb::Filter objects in Perl do not run until you invoke the run() method. The "--(no)autorun" option controls that behavior within Perl.

--help

Show help.

--man

Show full manual.
