=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

|
|
=head1 DESCRIPTION
|
|
|
|
pt-variable-advisor examines C<SHOW VARIABLES> for bad values and settings
|
|
according to the L<"RULES"> described below. It reports on variables that
|
|
match the rules, so you can find bad settings in your MySQL server.
|
|
|
|
At the time of this release, pt-variable-advisor only examples
|
|
C<SHOW VARIABLES>, but other input sources are planned like C<SHOW STATUS>
|
|
and C<SHOW SLAVE STATUS>.
|
|
|
|
=head1 RULES
|
|
|
|
These are the rules that pt-variable-advisor will apply to SHOW VARIABLES.
|
|
Each rule has three parts: an ID, a severity, and a description.
|
|
|
|
The rule's ID is a short, unique name for the rule. It usually relates
|
|
to the variable that the rule examines. If a variable is examined by
|
|
several rules, then the rules' IDs are numbered like "-1", "-2", "-N".
|
|
|
|
The rule's severity is an indication of how important it is that this
|
|
rule matched a query. We use NOTE, WARN, and CRIT to denote these
|
|
levels.
|
|
|
|
The rule's description is a textual, human-readable explanation of
|
|
what it means when a variable matches this rule. Depending on the
|
|
verbosity of the report you generate, you will see more of the text in
|
|
the description. By default, you'll see only the first sentence,
|
|
which is sort of a terse synopsis of the rule's meaning. At a higher
|
|
verbosity, you'll see subsequent sentences.
|
|
|
|

|
|
|
|
=item auto_increment
|
|
|
|
severity: note
|
|
|
|
Are you trying to write to more than one server in a dual-master or
|
|
ring replication configuration? This is potentially very dangerous and in
|
|
most cases is a serious mistake. Most people's reasons for doing this are
|
|
actually not valid at all.
|
|
|
|
=item concurrent_insert
|
|
|
|
severity: note
|
|
|
|
Holes (spaces left by deletes) in MyISAM tables might never be
|
|
reused.
|
|
|
|
=item connect_timeout
|
|
|
|
severity: note
|
|
|
|
A large value of this setting can create a denial of service
|
|
vulnerability.
|
|
|
|
=item debug
|
|
|
|
severity: crit
|
|
|
|
Servers built with debugging capability should not be used in
|
|
production because of the large performance impact.
|
|
|
|
=item delay_key_write
|
|
|
|
severity: warn
|
|
|
|
MyISAM index blocks are never flushed until necessary. If there is
|
|
a server crash, data corruption on MyISAM tables can be much worse than
|
|
usual.
|
|
|
|
=item flush
|
|
|
|
severity: warn
|
|
|
|
This option might decrease performance greatly.
|
|
|
|
=item flush_time
|
|
|
|
severity: warn
|
|
|
|
This option might decrease performance greatly.
|
|
|
|
=item have_bdb
|
|
|
|
severity: note
|
|
|
|
The BDB engine is deprecated. If you aren't using it, you should
|
|
disable it with the skip_bdb option.
|
|
|
|
=item init_connect
|
|
|
|
severity: note
|
|
|
|
The init_connect option is enabled on this server.
|
|
|
|
=item init_file
|
|
|
|
severity: note
|
|
|
|
The init_file option is enabled on this server.
|
|
|
|
=item init_slave
|
|
|
|
severity: note
|
|
|
|
The init_slave option is enabled on this server.
|
|
|
|
=item innodb_additional_mem_pool_size
|
|
|
|
severity: warn
|
|
|
|
This variable generally doesn't need to be larger than 20MB.
|
|
|
|
=item innodb_buffer_pool_size
|
|
|
|
severity: warn
|
|
|
|
The InnoDB buffer pool size is unconfigured. In a production
|
|
environment it should always be configured explicitly, and the default
|
|
10MB size is not good.
|
|
|
|
=item innodb_checksums
|
|
|
|
severity: warn
|
|
|
|
InnoDB checksums are disabled. Your data is not protected from
|
|
hardware corruption or other errors!
|
|
|
|
=item innodb_doublewrite
|
|
|
|
severity: warn
|
|
|
|
InnoDB doublewrite is disabled. Unless you use a filesystem that
|
|
protects against partial page writes, your data is not safe!
|
|
|
|
=item innodb_fast_shutdown
|
|
|
|
severity: warn
|
|
|
|
InnoDB's shutdown behavior is not the default. This can lead to
|
|
poor performance, or the need to perform crash recovery upon startup.
|
|
|
|
=item innodb_flush_log_at_trx_commit-1
|
|
|
|
severity: warn
|
|
|
|
InnoDB is not configured in strictly ACID mode. If there
|
|
is a crash, some transactions can be lost.
|
|
|
|
=item innodb_flush_log_at_trx_commit-2
|
|
|
|
severity: warn
|
|
|
|
Setting innodb_flush_log_at_trx_commit to 0 has no performance
|
|
benefits over setting it to 2, and more types of data loss are possible.
|
|
If you are trying to change it from 1 for performance reasons, you should
|
|
set it to 2 instead of 0.
|
|
|
|
=item innodb_force_recovery
|
|
|
|
severity: warn
|
|
|
|
InnoDB is in forced recovery mode! This should be used only
|
|
temporarily when recovering from data corruption or other bugs, not for
|
|
normal usage.
|
|
|
|
=item innodb_lock_wait_timeout
|
|
|
|
severity: warn
|
|
|
|
This option has an unusually long value, which can cause
|
|
system overload if locks are not being released.
|
|
|
|
=item innodb_log_buffer_size
|
|
|
|
severity: warn
|
|
|
|
The InnoDB log buffer size generally should not be set larger than
|
|
16MB. If you are doing large BLOB operations, InnoDB is not really a good
|
|
choice of engines anyway.
|
|
|
|
=item innodb_log_file_size
|
|
|
|
severity: warn
|
|
|
|
The InnoDB log file size is set to its default value, which is not
|
|
usable on production systems.
|
|
|
|
=item innodb_max_dirty_pages_pct
|
|
|
|
severity: note
|
|
|
|
The innodb_max_dirty_pages_pct is lower than the default. This can
|
|
cause overly aggressive flushing and add load to the I/O system.
|
|
|
|
=item flush_time
|
|
|
|
severity: warn
|
|
|
|
This setting is likely to cause very bad performance every
|
|
flush_time seconds.
|
|
|
|
=item key_buffer_size
|
|
|
|
severity: warn
|
|
|
|
The key buffer size is set to its default value, which is not good
|
|
for most production systems. In a production environment, key_buffer_size
|
|
should be larger than the default 8MB size.
|
|
|
|
=item large_pages
|
|
|
|
severity: note
|
|
|
|
Large pages are enabled.
|
|
|
|
=item locked_in_memory
|
|
|
|
severity: note
|
|
|
|
The server is locked in memory with --memlock.
|
|
|
|
=item log_warnings-1
|
|
|
|
severity: note
|
|
|
|
Log_warnings is disabled, so unusual events such as statements
|
|
unsafe for replication and aborted connections will not be logged to the
|
|
error log.
|
|
|
|
=item log_warnings-2
|
|
|
|
severity: note
|
|
|
|
Log_warnings must be set greater than 1 to log unusual events such
|
|
as aborted connections.
|
|
|
|
=item low_priority_updates
|
|
|
|
severity: note
|
|
|
|
The server is running with non-default lock priority for updates.
|
|
This could cause update queries to wait unexpectedly for read queries.
|
|
|
|
=item max_binlog_size
|
|
|
|
severity: note
|
|
|
|
The max_binlog_size is smaller than the default of 1GB.
|
|
|
|
=item max_connect_errors
|
|
|
|
severity: note
|
|
|
|
max_connect_errors should probably be set as large as your platform
|
|
allows.
|
|
|
|
=item max_connections
|
|
|
|
severity: warn
|
|
|
|
If the server ever really has more than a thousand threads running,
|
|
then the system is likely to spend more time scheduling threads than
|
|
really doing useful work. This variable's value should be considered in
|
|
light of your workload.
|
|
|
|
=item myisam_repair_threads
|
|
|
|
severity: note
|
|
|
|
myisam_repair_threads > 1 enables multi-threaded repair, which is
|
|
relatively untested and is still listed as beta-quality code in the
|
|
official documentation.
|
|
|
|
=item old_passwords
|
|
|
|
severity: warn
|
|
|
|
Old-style passwords are insecure. They are sent in plain text
|
|
across the wire.
|
|
|
|
=item optimizer_prune_level
|
|
|
|
severity: warn
|
|
|
|
The optimizer will use an exhaustive search when planning complex
|
|
queries, which can cause the planning process to take a long time.
|
|
|
|
=item port
|
|
|
|
severity: note
|
|
|
|
The server is listening on a non-default port.
|
|
|
|
=item query_cache_size-1
|
|
|
|
severity: note
|
|
|
|
The query cache does not scale to large sizes and can cause unstable
|
|
performance when larger than 128MB, especially on multi-core machines.
|
|
|
|
=item query_cache_size-2
|
|
|
|
severity: warn
|
|
|
|
The query cache can cause severe performance problems when it is
|
|
larger than 256MB, especially on multi-core machines.
|
|
|
|
=item read_buffer_size-1
|
|
|
|
severity: note
|
|
|
|
The read_buffer_size variable should generally be left at its
|
|
default unless an expert determines it is necessary to change it.
|
|
|
|
=item read_buffer_size-2
|
|
|
|
severity: warn
|
|
|
|
The read_buffer_size variable should not be larger than 8MB. It
|
|
should generally be left at its default unless an expert determines it is
|
|
necessary to change it. Making it larger than 2MB can hurt performance
|
|
significantly, and can make the server crash, swap to death, or just
|
|
become extremely unstable.
|
|
|
|
=item read_rnd_buffer_size-1
|
|
|
|
severity: note
|
|
|
|
The read_rnd_buffer_size variable should generally be left at its
|
|
default unless an expert determines it is necessary to change it.
|
|
|
|
=item read_rnd_buffer_size-2
|
|
|
|
severity: warn
|
|
|
|
The read_rnd_buffer_size variable should not be larger than 4M. It
|
|
should generally be left at its default unless an expert determines it is
|
|
necessary to change it.
|
|
|
|
=item relay_log_space_limit
|
|
|
|
severity: warn
|
|
|
|
Setting relay_log_space_limit can cause replicas to stop fetching binary logs
|
|
from their master immediately. This could increase the risk that your data will
|
|
be lost if the master crashes. If the replicas have encountered a limit on relay
|
|
log space, then it is possible that the latest transactions exist only on the
|
|
master and no replica has retrieved them.
|
|
|
|
=item slave_net_timeout
|
|
|
|
severity: warn
|
|
|
|
This variable is set too high. This is too long to wait before
|
|
noticing that the connection to the master has failed and retrying. This
|
|
should probably be set to 60 seconds or less. It is also a good idea to
|
|
use pt-heartbeat to ensure that the connection does not appear to time out
|
|
when the master is simply idle.
|
|
|
|
=item slave_skip_errors
|
|
|
|
severity: crit
|
|
|
|
You should not set this option. If replication is having errors,
|
|
you need to find and resolve the cause of that; it is likely that your
|
|
slave's data is different from the master. You can find out with
|
|
pt-table-checksum.
|
|
|
|
=item sort_buffer_size-1
|
|
|
|
severity: note
|
|
|
|
The sort_buffer_size variable should generally be left at its
|
|
default unless an expert determines it is necessary to change it.
|
|
|
|
=item sort_buffer_size-2
|
|
|
|
severity: note
|
|
|
|
The sort_buffer_size variable should generally be left at its
|
|
default unless an expert determines it is necessary to change it. Making
|
|
it larger than a few MB can hurt performance significantly, and can make
|
|
the server crash, swap to death, or just become extremely unstable.
|
|
|
|
=item sql_notes
|
|
|
|
severity: note
|
|
|
|
This server is configured not to log Note level warnings to the
|
|
error log.
|
|
|
|
=item sync_frm
|
|
|
|
severity: warn
|
|
|
|
It is best to set sync_frm so that .frm files are flushed safely to
|
|
disk in case of a server crash.
|
|
|
|
=item tx_isolation-1
|
|
|
|
severity: note
|
|
|
|
This server's transaction isolation level is non-default.
|
|
|
|
=item tx_isolation-2
|
|
|
|
severity: warn
|
|
|
|
Most applications should use the default REPEATABLE-READ transaction
|
|
isolation level, or in a few cases READ-COMMITTED.
|
|
|
|
=item expire_logs_days
|
|
|
|
severity: warn
|
|
|
|
Binary logs are enabled, but automatic purging is not enabled. If
|
|
you do not purge binary logs, your disk will fill up. If you delete
|
|
binary logs externally to MySQL, you will cause unwanted behaviors.
|
|
Always ask MySQL to purge obsolete logs, never delete them externally.
|
|
|
|
=item innodb_file_io_threads
|
|
|
|
severity: note
|
|
|
|
This option is useless except on Windows.
|
|
|
|
=item innodb_data_file_path
|
|
|
|
severity: note
|
|
|
|
Auto-extending InnoDB files can consume a lot of disk space that is
|
|
very difficult to reclaim later. Some people prefer to set
|
|
innodb_file_per_table and allocate a fixed-size file for ibdata1.
|
|
|
|
=item innodb_flush_method
|
|
|
|
severity: note
|
|
|
|
Most production database servers that use InnoDB should set
|
|
innodb_flush_method to O_DIRECT to avoid double-buffering, unless the I/O
|
|
system is very low performance.
|
|
|
|
=item innodb_locks_unsafe_for_binlog
|
|
|
|
severity: warn
|
|
|
|
This option makes point-in-time recovery from binary logs, and
|
|
replication, untrustworthy if statement-based logging is used.
|
|
|
|
=item innodb_support_xa
|
|
|
|
severity: warn
|
|
|
|
MySQL's internal XA transaction support between InnoDB and the
|
|
binary log is disabled. The binary log might not match InnoDB's state
|
|
after crash recovery, and replication might drift out of sync due to
|
|
out-of-order statements in the binary log.
|
|
|
|
=item log_bin
|
|
|
|
severity: warn
|
|
|

=item myisam_recover_options
|
|
|
|
severity: warn

severity: note
|
|
|
|
The effective minimum size of in-memory implicit temporary tables
|

|
|
|
Show help and exit.
|
|
|
|
=item --host
|
|
|
|
short form: -h; type: string
|
|
|
|
Connect to host.
|
|
|
|
=item --ignore-rules
|
|
|
|
type: hash
|
|
|
|
Ignore these rule IDs.
|
|
|
|
Specify a comma-separated list of rule IDs (e.g. LIT.001,RES.002,etc.)
|
|
to ignore.
|
|
|
|
=item --password
|
|
|
|
short form: -p; type: string
|
|
|
|
Password to use when connecting.
|
|
|
|
=item --pid
|
|
|
|
type: string
|
|
|
|
Create the given PID file. The tool won't start if the PID file already
|
|
exists and the PID it contains is different than the current PID. However,
|
|
if the PID file exists and the PID it contains is no longer running, the
|
|
tool will overwrite the PID file with the current PID. The PID file is
|
|
removed automatically when the tool exits.
|
|
|
|
=item --port
|
|
|
|
short form: -P; type: int
|
|
|
|
Port number to use for connection.
|
|
|
|
=item --set-vars
|
|
|
|
type: Array
|
|
|
|
Set the MySQL variables in this comma-separated list of C<variable=value> pairs.
|
|
|
|
By default, the tool sets:
|
|
|
|
=for comment ignore-pt-internal-value
|
|
MAGIC_set_vars
|
|
|
|
wait_timeout=10000
|
|
|
|
Variables specified on the command line override these defaults. For
|
|
example, specifying C<--set-vars wait_timeout=500> overrides the defaultvalue of C<10000>.
|
|
|
|
The tool prints a warning and continues if a variable cannot be set.
|
|
|
|
=item --socket
|
|
|
|
short form: -S; type: string
|
|
|
|
Socket file to use for connection.
|
|
|
|
=item --source-of-variables
|
|
|
|
type: string; default: mysql
|
|
|
|
Read C<SHOW VARIABLES> from this source. Possible values are "mysql", "none"
|
|
or a file name. If "mysql" is specified then you must also specify a DSN
|
|
on the command line.
|
|
|
|
=item --user
|
|
|
|
short form: -u; type: string
|
|
|
|

|
|
|
|
=item --verbose
|
|
|
|
short form: -v; cumulative: yes; default: 1
|
|
|
|
Increase verbosity of output. At the default level of verbosity, the
|
|
program prints only the first sentence of each rule's description. At
|
|
higher levels, the program prints more of the description.
|
|
|
|
=item --version
|
|
|
|
Show version and exit.
|
|
|
|
=item --[no]version-check
|
|
|
|
default: yes
|
|
|
|
Check for the latest version of Percona Toolkit, MySQL, and other programs.
|
|
|
|
This is a standard "check for updates automatically" feature, with two
|
|
additional features. First, the tool checks the version of other programs
|
|
on the local system in addition to its own version. For example, it checks
|
|
the version of every MySQL server it connects to, Perl, and the Perl module
|
|
DBD::mysql. Second, it checks for and warns about versions with known
|
|
problems. For example, MySQL 5.5.25 had a critical bug and was re-released
|
|
as 5.5.25a.
|
|
|
|
Any updates or known problems are printed to STDOUT before the tool's normal
|
|
output. This feature should never interfere with the normal operation of the
|
|
tool.

=head1 DSN OPTIONS
|
|
|
|
These DSN options are used to create a DSN. Each option is given like
|
|
C<option=value>. The options are case-sensitive, so P and p are not the
|
|
same option. There cannot be whitespace before or after the C<=> and
|
|
if the value contains whitespace it must be quoted. DSN options are
|
|
comma-separated. See the L<percona-toolkit> manpage for full details.

=head1 ENVIRONMENT
|
|
|
|
The environment variable C<PTDEBUG> enables verbose debugging output to STDERR.
|
|
To enable debugging and capture all output to a file, run the tool like:
|
|
|
|
PTDEBUG=1 pt-variable-advisor ... > FILE 2>&1
|
|
|
|
Be careful: debugging output is voluminous and can generate several megabytes
|
|
of output.
|
|
|
|
=head1 SYSTEM REQUIREMENTS
|
|
|
|
You need Perl, DBI, DBD::mysql, and some core packages that ought to be
|
|
installed in any reasonably new version of Perl.
|
|
|
