* Package name : mysqltunner Version : 20071201 Upstream Author : Major Hayden <[EMAIL PROTECTED]> * URL : http://www.mysqltuner.com/ * License : GPL Programming Lang : Perl Description : high-performance MySQL tuning script High-performance MySQL tuning script written in perl that will provide you with a snapshot of a MySQL server?s health. Based on the statistics gathered, specific recommendations will be provided that will increase a MySQL server's efficiency and performance. The script gives you automated MySQL tuning that is on the level of what you would receive from a MySQL DBA. . Features: . * Memory Usage: Calculates MySQL memory usage at max load and makes recommendations for increasing or decreasing the MySQL memory footprint. Per-thread and server-wide buffer data is calculated separately for an accurate snapshot of the server?s configuration. * Slow Queries: Reviews the amount of slow queries relative to the total queries. Slow query time limits are also analyzed and recommendations are made. * Connections: Current and historical connection counts are reviewed. * Key Buffer: Takes configuration data and compares it to the actual indexes found in MyISAM tables. Key cache hit rates are calculated and variable adjustments are suggested. * Query Cache: Query cache hit rates and usage percentages are used to make recommendations for the query cache configuration variables. * Sorting & Joins: Per-thread buffers that affect sorts and joins are reviewed along with the statistics from the queries run against the server. * Temporary Tables: Variable recommendations are made to reduce temporary tables that are written to the disk. * Table Cache: Compares total tables opened to the currently open tables. Calculates the table cache hit rate in order to make suggestions. * Open Files: Determines if the server will approach or run into the open file limit set by the operating system or the MySQL server itself. * Table Locks: Finds table locking that forces queries to wait and makes suggestions for reducing locks that require a wait. * Thread Cache: Calculates how many times MySQL must create a new thread to respond to a query. * Aborted Connections: Finds applications that are not closing connections to MySQL properly. * Read/Write Ratios: Calculates the percentage of read and write operations on your MySQL installation. -- System Information: Debian Release: lenny/sid APT prefers testing APT policy: (500, 'testing') Architecture: i386 (i686) Kernel: Linux 2.6.18-3-686 (SMP w/2 CPU cores) Locale: LANG=en_US, LC_CTYPE=en_US (charmap=ISO-8859-1) Shell: /bin/sh linked to /bin/bash -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
