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:

-d
Enable debugging output.
-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.
