PT-MEXT(1) User Contributed Perl Documentation PT-MEXT(1) NAME pt-mext - Look at many samples of MySQL "SHOW GLOBAL STATUS" side-by-side. SYNOPSIS Usage: pt-mext [OPTIONS] -- COMMAND pt-mext columnizes repeated output from a program like mysqladmin extended. Get output from "mysqladmin": pt-mext -r -- mysqladmin ext -i10 -c3 Get output from a file: pt-mext -r -- cat mysqladmin-output.txt 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: o Read the tool's documentation o Review the tool's known "BUGS" o Test the tool on a non-production server o Backup your production server and verify the backups DESCRIPTION pt-mext executes the "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 "--relative" option is given, it first subtracts each sample from the one after it before printing results. OPTIONS --help Show help and exit. --relative short form: -r Subtract each column from the previous column. --version Show version and exit. ENVIRONMENT This tool does not use any environment variables. SYSTEM REQUIREMENTS This tool requires the Bourne shell (/bin/sh) and the seq program. BUGS For a list of known bugs, see <http://www.percona.com/bugs/pt-mext>. Please report bugs at <https://jira.percona.com/projects/PT>. Include the following information in your bug report: o Complete command-line used to run the tool o Tool "--version" o MySQL version of all servers involved o Output from the tool including STDERR o Input files (log/dump/config files, etc.) If possible, include debugging output by running the tool with "PTDEBUG"; see "ENVIRONMENT".
