=head1 NAME
pt-mext - Look at many samples of MySQL C<SHOW GLOBAL STATUS> side-by-side.
=head1 SYNOPSIS
Usage: pt-mext [OPTIONS] -- COMMAND
pt-mext columnizes repeated output from a program like mysqladmin extended.
Get output from C<mysqladmin>:
pt-mext -r -- mysqladmin ext -i10 -c3
Get output from a file:
pt-mext -r -- cat mysqladmin-output.txt
=head1 RISKS
Percona Toolkit is mature, proven in the real world, and well tested,
but all database tools can pose a risk to the system and the database
server. Before using this tool, please:
=over
=item * Read the tool's documentation
=item * Review the tool's known L<"BUGS">
=item * Test the tool on a non-production server
=item * Backup your production server and verify the backups
=back
=head1 DESCRIPTION
pt-mext executes the C<COMMAND> you specify, and reads through the result one
line at a time. It places each line into a temporary file. When it finds a
blank line, it assumes that a new sample of SHOW GLOBAL STATUS is starting,
and it creates a new temporary file. At the end of this process, it has a
number of temporary files. It joins the temporary files together side-by-side
and prints the result. If the L<"-r"> option is given, it first subtracts
each sample from the one after it before printing results.
=head1 OPTIONS
=over
=item --help
Show help and exit.
=item --relative
short form: -r
Subtract each column from the previous column.
=item --version
Show version and exit.
=back
=head1 ENVIRONMENT
This tool does not use any environment variables.
=head1 SYSTEM REQUIREMENTS
This tool requires the Bourne shell (F</bin/sh>) and the seq program.
=head1 BUGS
For a list of known bugs, see L<http://www.percona.com/bugs/pt-mext>.
Please report bugs at L<https://bugs.launchpad.net/percona-toolkit>.
Include the following information in your bug report:
=over
=item * Complete command-line used to run the tool
=item * Tool L<"--version">
=item * MySQL version of all servers involved
=item * Output from the tool including STDERR
=item * Input files (log/dump/config files, etc.)
=back
If possible, include debugging output by running the tool with C<PTDEBUG>;
see L<"ENVIRONMENT">.
