五、基本使用
1.使用参数说明
(1). --log-type (-lt) type logs:
通过这个参数来制定log的类型,主要有slow, general, binary, msl, udl,分析slow log时通过制定为slow.
(2). --sort:
制定使用什么参数来对分析结果进行排序,默认是按照t_sum来进行排序。
t_sum按总时间排序, c_sum按总次数排序
(3). --top:
显示sql的数量,默认是10,表示取按规则排序的前多少条
(4). --statement-filter (-sf) [+-][TYPE]:
过滤sql语句的类型,比如select、update、drop. [TYPE]有SELECT, CREATE, DROP, UPDATE, INSERT,例如"+SELECT,INSERT",不出现的默认是-,即不包括。
(5). --databases db:
要处理哪个库的日志:
2.统计参数说明
(1). queries total: 总查询次数
(2). unique:去重后的sql数量
(3). sorted by : 输出报表的内容排序 最重大的慢sql统计信息, 包括 平均执行时间, 等待锁时间, 结果行的总数, 扫描的行总数.
(4). Count: sql的执行次数及占总的slow log数量的百分比.
(5). Time: 执行时间, 包括总时间, 平均时间, 最小, 最大时间, 时间占到总慢sql时间的百分比.
(6). 95% of Time: 去除最快和最慢的sql, 覆盖率占95%的sql的执行时间.
(7). Lock Time: 等待锁的时间.
(8).95% of Lock: 95%的慢sql等待锁时间.
(9).Rows sent: 结果行统计数量, 包括平均, 最小, 最大数量.
(10).Rows examined: 扫描的行数量.
(11).Database: 属于哪个数据库.
(12).Users: 哪个用户,IP, 占到所有用户执行的sql百分比.
(13). Query abstract: 抽象后的sql语句.
(14). Query sample: sql语句.
3.使用范例
(1).统计慢查询文件为dowload_server1-slow.log的所有select的慢查询sql,并显示执行时间最长的10条sql,并写到sql_time.sql中去
mysqlsla -lt slow -sf "+select" -top 10 dowload_server1-slow.log >test_time.log
(2).统计慢查询文件为dowload_server1-slow.log的数据库为ultraxsmutf8的所有select和update的慢查询sql,并查询次数最多的100条sql,并写到sql_num.sql中去
mysqlsla -lt slow -sf "+select,update" -top 100 -sort c_sum -db ultraxsmutf8 dowload_server1-slow.log >num_time.log

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

You can open phpMyAdmin through the following steps: 1. Log in to the website control panel; 2. Find and click the phpMyAdmin icon; 3. Enter MySQL credentials; 4. Click "Login".

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

Redis uses a single threaded architecture to provide high performance, simplicity, and consistency. It utilizes I/O multiplexing, event loops, non-blocking I/O, and shared memory to improve concurrency, but with limitations of concurrency limitations, single point of failure, and unsuitable for write-intensive workloads.

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL and SQL are essential skills for developers. 1.MySQL is an open source relational database management system, and SQL is the standard language used to manage and operate databases. 2.MySQL supports multiple storage engines through efficient data storage and retrieval functions, and SQL completes complex data operations through simple statements. 3. Examples of usage include basic queries and advanced queries, such as filtering and sorting by condition. 4. Common errors include syntax errors and performance issues, which can be optimized by checking SQL statements and using EXPLAIN commands. 5. Performance optimization techniques include using indexes, avoiding full table scanning, optimizing JOIN operations and improving code readability.

Effective monitoring of Redis databases is critical to maintaining optimal performance, identifying potential bottlenecks, and ensuring overall system reliability. Redis Exporter Service is a powerful utility designed to monitor Redis databases using Prometheus. This tutorial will guide you through the complete setup and configuration of Redis Exporter Service, ensuring you seamlessly build monitoring solutions. By studying this tutorial, you will achieve fully operational monitoring settings
