DSN. Information is printed to C<STDOUT>, and it can also be saved to a
|
|
table by specifying L<"--dest">. The tool runs for forever unless
|
|
L<"--run-time"> or L<"--iterations"> is specified.
|
|
|
|
Print foreign key errors on host1:
|
|
|
|
pt-fk-error-logger h=host1
|
|
|
|
Print foreign key errors on host1 once then exit:
|
|
|
|
pt-fk-error-logger h=host1 --iterations 1
|
|
|
|
Save foreign key errors on host1 to percona_schema.fke on host2:
|
|
|
|
pt-fk-error-logger h=host1 --dest h=host2,D=percona_schema,t=fke

=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-fk-error-logger prints or saves the foreign key errors text from
|
|
C<SHOW INNODB STATUS>. The errors are not parsed or interpreted in any
|
|
way. Foreign key errors are uniquely identified by their timestamp.
|
|
Only new (more recent) errors are printed or saved.
|
|
|
|
By default the tool runs forever, checking every L<"--interval"> seconds
|
|
for new foreign key errors. Specify L<"--run-time"> and/or L<"--iterations">
|
|
to limit how long the tool runs.
|
|
|
|
=head1 OUTPUT
|
|
|
|
The foreign key error text from C<SHOW ENGINE INNODB STATUS> is printed
|
|
to C<STDOUT>, unless L<"--quiet"> is specified. Errors and warnings
|
|
are printed to C<STDERR>.
|
|
|
|
=head1 OPTIONS
|
|
|
|
This tool accepts additional command-line arguments. Refer to the
|
|
L<"SYNOPSIS"> and usage information for details.
|
|
|
|
=over
|
|
|
|
=item --ask-pass
|
|
|
|
Prompt for a password when connecting to MySQL.
|
|
|
|
=item --charset
|
|
|
|
short form: -A; type: string
|
|
|
|
Default character set. If the value is utf8, sets Perl's binmode on
|
|
STDOUT to utf8, passes the mysql_enable_utf8 option to DBD::mysql, and runs SET
|
|
NAMES UTF8 after connecting to MySQL. Any other value sets binmode on STDOUT
|
|
without the utf8 layer, and runs SET NAMES after connecting to MySQL.
|
|
|
|
=item --config
|
|
|
|
type: Array
|
|
|
|
Read this comma-separated list of config files; if specified, this must be the
|
|
first option on the command line.
|
|
|
|
=item --daemonize
|
|
|
|
Fork to the background and detach from the shell. POSIX operating systems only.
|
|
|
|
=item --database
|
|
|
|
short form: -D; type: string
|
|
|
|
Connect to this database.
|
|
|
|
=item --defaults-file
|
|
|
|
short form: -F; type: string
|
|
|
|
Only read mysql options from the given file. You must give an absolute
|
|
pathname.
|
|
|
|
=item --dest
|
|
|
|
type: DSN
|
|
|
|
Save foreign key errors in this table. The DSN must specify a database (D)
|
|
and table (t).
|
|
|
|
Missing DSN values are inherited from the DSN being monitored, so you
|
|
can omit most values if you're saving foreign key errors on the same
|
|
host.
|
|
|
|
The following table is suggested:
|
|
|
|
CREATE TABLE foreign_key_errors (
|
|
ts datetime NOT NULL,
|
|
error text NOT NULL,
|
|
PRIMARY KEY (ts)
|
|
)
|
|
|
|
The only information saved is the timestamp and the foreign key error text.
|
|
|
|
=item --help
|
|
|
|
Show help and exit.
|
|
|
|
=item --host
|
|
|
|
short form: -h; type: string
|
|
|
|
Connect to host.
|
|
|
|
=item --interval
|
|
|
|
type: time; default: 30
|
|
|
|
How often to check for foreign key errors.
|
|
|
|
=item --iterations
|
|
|
|
type: int
|
|
|
|
How many times to check for foreign key errors. By default, this option
|
|
is undefined which means an infinite number of iterations. The tool always
|
|
exits for L<"--run-time">, regardless of the value specified for this option.
|
|
For example, the tool will exit after 1 minute with
|
|
C<--run-time 1m --iterations 4 --interval 30> because 4 iterations at 30
|
|
second intervals would take 2 minutes, longer than the 1 mintue run-time.
|
|
|
|
=item --log
|
|
|
|
type: string
|
|
|
|
Print all output to this file when daemonized.
|
|
|
|
=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 --quiet
|
|
|
|
Do not print foreign key errors; only print errors and warnings to C<STDERR>.
|
|
|
|
=item --run-time
|
|
|
|
type: time
|
|
|
|
How long to run before exiting. By default, the tool runs forever.
|
|
|
|
=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 --user
|
|
|
|
short form: -u; type: string
|
|
|
|
User for login if not current user.
|
|
|
|
=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-fk-error-logger ... > 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.
|
|
|
|

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