=head1 NAME

pt-summary - Summarize system information nicely.

=head1 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 many types of Unix systems.

Download and run:

   wget http://percona.com/get/pt-summary
   bash ./pt-summary

=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-summary runs a large variety of commands to inspect system status and
configuration, saves the output into files in a temporary directory, 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.

=head1 OUTPUT

Many of the outputs from this tool are deliberately rounded to show their
magnitude but not the exact detail. This is called fuzzy-rounding. The idea is
that it doesn't matter whether a particular counter is 918 or 921; such a small
variation is insignificant, and only makes the output hard to compare to other
servers. Fuzzy-rounding rounds in larger increments as the input grows. It
begins by rounding to the nearest 5, then the nearest 10, nearest 25, and then
repeats by a factor of 10 larger (50, 100, 250), and so on, as the input grows.

The following is a simple report generated from a CentOS virtual machine,
broken into sections with commentary following each section. Some long lines
are reformatted for clarity when reading this documentation as a manual page in
a terminal.

operating system.

 # Processor ##################################################
   Processors | physical = 1, cores = 0, virtual = 1, hyperthreading = no
       Speeds | 1x2510.626
       Models | 1xIntel(R) Core(TM) i5-2400S CPU @ 2.50GHz

         Free | 29.0M
         Used | physical = 474.2M, swap allocated = 1.0M,

  Locator  Size  Speed    Form Factor  Type    Type Detail
  =======  ====  =====    ===========  ====    ===========

Information about memory is gathered from C<free>. The Used statistic is the
total of the rss sizes displayed by C<ps>. The Dirty statistic for the cached
value comes from F</proc/meminfo>. On Linux, the swappiness settings are
gathered from C<sysctl>. The final portion of this section is a table of the
DIMMs, which comes from C<dmidecode>. In this example there is no output.

 # Mounted Filesystems ########################################
   Filesystem                       Size Used Type  Opts Mountpoint
   /dev/mapper/VolGroup00-LogVol00   15G  17% ext3  rw   /
   /dev/sda1                         99M  13% ext3  rw   /boot
   tmpfs                            252M   0% tmpfs rw   /dev/shm

The mounted filesystem section is a combination of information from C<mount> and
C<df>. This section is skipped if you disable L<"--summarize-mounts">.

 # Disk Schedulers And Queue Size #############################
         dm-0 | UNREADABLE
         dm-1 | UNREADABLE
          hdc | [cfq] 128
          md0 | UNREADABLE
          sda | [cfq] 128

The disk scheduler information is extracted from the F</sys> filesystem in
Linux.

 # Disk Partioning ############################################

 /dev/sda2    Part         14       2088        17059230720

Information about disk partitioning comes from C<fdisk -l>.

These lines are from the files of the same name in the F</proc/sys/fs>
directory on Linux. Read the C<proc> man page to learn about the meaning of
these files on your system.

 # LVM Volumes ################################################
 LV       VG         Attr   LSize   Origin Snap% Move Log Copy% Convert

 LogVol01 VolGroup00 -wi-ao   9.75G   

This section shows the output of C<lvs>.

 # RAID Controller ############################################
   Controller | No RAID controller detected

The tool can detect a variety of RAID controllers by examining C<lspci> and
C<dmesg> information. If the controller software is installed on the system, in
many cases it is able to execute status commands and show a summary of the RAID
controller's status and configuration. If your system is not supported, please
file a bug report.

 # Network Config #############################################
   Controller | Intel Corporation 82540EM Gigabit Ethernet Controller
  FIN Timeout | 60
   Port Range | 61000

The network controllers attached to the system are detected from C<lspci>. The
TCP/IP protocol configuration parameters are extracted from C<sysctl>. You can skip this section by disabling the L<"--summarize-network"> option.

 # Interface Statistics #######################################
 interface rx_bytes rx_packets rx_errors tx_bytes tx_packets tx_errors
 ========= ======== ========== ========= ======== ========== =========
 lo        60000000      12500         0 60000000      12500         0

Interface statistics are gathered from C<ip -s link> and are fuzzy-rounded. The
columns are received and transmitted bytes, packets, and errors.  You can skip
this section by disabling the L<"--summarize-network"> option.

 # Network Connections ########################################

   States of connections
     ESTABLISHED         5
     LISTEN              8

This section shows a summary of network connections, retrieved from C<netstat>
and "fuzzy-rounded" to make them easier to compare when the numbers grow large.
There are two sub-sections showing how many connections there are per origin
and destination IP address, and a sub-section showing the count of ports in
use.  The section ends with the count of the network connections' states.  You
can skip this section by disabling the L<"--summarize-network"> option.

This section shows the first few lines of C<top> so that you can see what
processes are actively using CPU time.  The notable processes include the SSH
daemon and any process whose out-of-memory-killer priority is set to 17. You
