NAME
****
pt-summary - Summarize system information in a nice way.
********
SYNOPSIS
********
Usage: pt-summary
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:
.. code-block:: perl
wget http://percona.com/get/pt-summary
bash ./pt-summary
Download and run in a single step:
.. code-block:: perl
wget -O- http://percona.com/get/summary | bash
*****
RISKS
*****
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 <http://www.percona.com/bugs/pt-summary>`_.
See also "BUGS" for more information on filing bugs and getting help.
***********
DESCRIPTION
***********
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.
*******
OPTIONS
*******
This tool does not have any command-line options.
