.. program:: pt-sift ================== :program:`pt-sift` ================== NAME ==== :program:`pt-sift` - Browses files created by pt-stalk. SYNOPSIS ======== Usage ----- :: pt-sift FILE|PREFIX|DIRECTORY :program:`pt-sift` browses files created by pt-stalk. If no options are given, the tool browses all pt-stalk files in ``/var/lib/pt-stalk`` if that directory exists, else the current working directory is used. If a FILE is given, the tool browses files with the same prefix in the given file's directory. If a PREFIX is given, the tool browses files in ``/var/lib/pt-stalk`` (or the current working directory) with the same prefix. If a DIRECTORY is given, the tool browses all pt-stalk files in it. 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: * Read the tool's documentation * Review the tool's known "BUGS" * Test the tool on a non-production server * Backup your production server and verify the backups DESCRIPTION =========== :program:`pt-sift` downloads other tools that it might need, such as pt-diskstats, and then makes a list of the unique timestamp prefixes of all the files in the directory, as written by the pt-stalk tool. If the user specified a timestamp on the command line, then it begins with that sample of data; otherwise it begins by showing a list of the timestamps and prompting for a selection. Thereafter, it displays a summary of the selected sample, and the user can navigate and inspect with keystrokes. The keystroke commands you can use are as follows: * d Sets the action to start the pt-diskstats tool on the sample's disk performance statistics. * i Sets the action to view the first INNODB STATUS sample in less. * m Displays the first 4 samples of SHOW STATUS counters side by side with the pt-mext tool. * n Summarizes the first sample of netstat data in two ways: by originating host, and by connection state. * j Select the next timestamp as the active sample. * k Select the previous timestamp as the active sample. * q Quit the program. * 1 Sets the action for each sample to the default, which is to view a summary of the sample. * 0 Sets the action to just list the files in the sample. * * Sets the action to view all of the sample's files in the less program. OPTIONS ======= .. option:: --help Show help and exit. .. option:: --version Show version and exit. ENVIRONMENT =========== This tool does not use any environment variables. SYSTEM REQUIREMENTS =================== This tool requires Bash v3 and the following programs: pt-diskstats, pt-pmp, pt-mext, and pt-align. If these programs are not in your PATH, they will be fetched from the Internet if curl is available. BUGS ==== For a list of known bugs, see `https://jira.percona.com/projects/PT/issues `_. Please report bugs at `https://jira.percona.com/projects/PT `_. Include the following information in your bug report: * Complete command-line used to run the tool * Tool :option:`--version` * MySQL version of all servers involved * Output from the tool including STDERR * Input files (log/dump/config files, etc.) If possible, include debugging output by running the tool with ``PTDEBUG``; see "ENVIRONMENT". ATTENTION ========= Using might expose passwords. When debug is enabled, all command line parameters are shown in the output.
