pt-summary - Summarize system information in a nice way.
pt-summary conveniently summarizes the status and configuration of a server. It is not a tuning tool or diagnosis tool. It produces a report that is easy to diff and can be pasted into emails without losing the formatting. This tool works well on Linux systems.
Download and run:
wget http://percona.com/get/pt-summary bash ./pt-summary
Download and run in a single step:
wget -O- http://percona.com/get/summary | bash
The following section is included to inform users about the potential risks, whether known or unknown, of using this tool. The two main categories of risks are those created by the nature of the tool (e.g. read-only tools vs. read-write tools) and those created by bugs.
pt-summary is a read-only tool. It should be very low-risk.
At the time of this release, we know of no bugs that could cause serious harm to users.
The authoritative source for updated information is always the online issue tracking system. Issues that affect this tool will be marked as such. You can see a list of such issues at the following URL: http://www.percona.com/bugs/pt-summary.
See also “BUGS” for more information on filing bugs and getting help.
pt-summary runs a large variety of commands to inspect system status and configuration, saves the output into files in /tmp, and then runs Unix commands on these results to format them nicely. It works best when executed as a privileged user, but will also work without privileges, although some output might not be possible to generate without root.
This tool does not have any command-line options.
The PT_SUMMARY_SKIP environment variable specifies a comma-separated list of things to skip:
MOUNT: Don't print out mounted filesystems and disk fullness. NETWORK: Don't print out information on network controllers & config. PROCESS: Don't print out top processes and vmstat information.
This tool requires the Bourne shell (/bin/sh).

This tool is part of Percona Toolkit, a collection of advanced command-line tools developed by Percona for MySQL support and consulting. Percona Toolkit was forked from two projects in June, 2011: Maatkit and Aspersa. Those projects were created by Baron Schwartz and developed primarily by him and Daniel Nichter, both of whom are employed by Percona.
