maatkit - Essential command-line utilities for MySQL.
maatkit, formerly MySQL Toolkit, is a collection of command-line utilities that provide missing functionality for MySQL. Some of the tools implement lacking server functionality, such as online consistency checks for master/slave replication; others are client-side utilities such as a query profiler.
The following tools are included:
$Revision: 1972 $ mk-archiver 1.0.9 mk-deadlock-logger 1.0.10 mk-duplicate-key-checker 1.1.6 mk-find 0.9.11 mk-heartbeat 1.0.9 mk-parallel-dump 1.0.8 mk-parallel-restore 1.0.7 mk-query-profiler 1.1.10 mk-show-grants 1.0.10 mk-slave-delay 1.0.7 mk-slave-find 1.0.1 mk-slave-move 0.9.1 mk-slave-prefetch 1.0.2 mk-slave-restart 1.0.7 mk-table-checksum 1.1.27 mk-table-sync 1.0.7 mk-visual-explain 1.0.8
Archive rows from a MySQL table into another table or a file. See the mk-archiver manpage.
Filter checksums from mk-table-checksum. See the mk-checksum-filter manpage.
Extract and log MySQL deadlock information. See the mk-deadlock-logger manpage.
Find possible duplicate indexes and foreign keys on MySQL tables. See the mk-duplicate-key-checker manpage.
Find MySQL tables and execute actions, like GNU find. See the mk-find manpage.
Monitor MySQL replication delay. See the mk-heartbeat manpage.
Dump sets of MySQL tables in parallel. See the mk-parallel-dump manpage.
Load files into MySQL in parallel. See the mk-parallel-restore manpage.
Compact the output from mk-query-profiler. See the mk-profile-compact manpage.
Execute SQL statements and print statistics, or measure activity caused by other processes. See the mk-query-profiler manpage.
Canonicalize and print MySQL grants so you can effectively replicate, compare and version-control them. See the mk-show-grants manpage.
Make a MySQL slave server lag behind its master. See the mk-slave-delay manpage.
Find MySQL replication slaves and execute commands on them. See the mk-slave-find manpage.
Move a MySQL slave around in the replication hierarchy. See the mk-slave-move manpage.
Pipeline relay logs on a MySQL slave to pre-warm caches. See the mk-slave-prefetch manpage.
Watch and restart MySQL replication after errors. See the mk-slave-restart manpage.
Perform an online replication consistency check, or checksum MySQL tables efficiently on one or many servers. See the mk-table-checksum manpage.
Synchronize MySQL tables efficiently. See the mk-table-sync manpage.
Format EXPLAIN output as a tree. See the mk-visual-explain manpage.
See also the the maatkitdsn manpage documentation, which explains how to use DSNs to connect to MySQL.
Strictly speaking these tools require no installation; you should be able to run them stand-alone. However, on UNIX-ish systems you can use the standard Perl installation sequence:
cd <package directory> perl Makefile.PL make install
You need Perl, DBI, DBD::mysql, and some core packages that ought to be installed in any reasonably new version of Perl.
If you find bugs, need features, etc please use the bug tracker, forums, and mailing lists at http://sourceforge.net/projects/maatkit.
