Introduction to MySQL Enterprise Monitor

This document discusses the Performance Schema in MySQL, which records instrumentation data to help profile and monitor database activity. It provides an overview of the Performance Schema's components and tables, how it has evolved between MySQL versions to include more metrics and functionality, and examples of how to query the tables to analyze wait events, statements, stages and other performance data.

MySQL Monitoring Mechanisms

The 5.5 and 5.6 releases of MySQL introduce several new mechanisms that provide improved monitoring and performance tuning functionality. Examples are performance schemas, InnoDB metrics tables, optimizer trace, and extended explain functionality. This session outlines the vision for monitoring-related functionality in MySQL and presents an overview of the new mechanisms. It shows how these are integrated with MySQL management tools. Furthermore, it discusses how these mechanisms can be utilized by application developers, DBAs, and production engineers for tracking down performance issues and monitoring production systems.

MySQL's Performance Schema, SYS Schema and Workbench Integration

Mario Beck

This document discusses the Performance Schema and SYS schema features in MySQL. It provides an overview of the Performance Schema, which records instrumentation data about the server's internal operations. It describes improvements made in MySQL 5.7 for profiling server performance. It also introduces the SYS schema, which provides views, procedures and functions to make Performance Schema data easier to analyze for common DBA and developer use cases.

MySQL for Oracle DBAs

This document provides an overview of MySQL for Oracle DBAs, covering topics such as MySQL architecture, backup and recovery strategies, managing space and tables, and connecting MySQL to Oracle. The key points discussed include MySQL's product architecture and internal memory structures, filesystem layout for binaries, data and log files, InnoDB and MyISAM storage engines for managing space, and using tools like mysqldump, mysqlhotcopy, and mysqlbinlog for backups and point-in-time recovery.

MySQL Monitoring Mechanisms

This document summarizes MySQL's monitoring mechanisms and how they have evolved over time. It discusses tools like SHOW statements, INFORMATION_SCHEMA, slow/general query logs, and EXPLAIN that provided limited visibility in past versions. MySQL 5.5 introduced the Performance Schema framework for detailed instrumentation. Subsequent versions have expanded instrumentation to provide more developer-focused statistics on statements, stages, I/O, locks and more. New INFORMATION_SCHEMA tables in 5.6 provide additional InnoDB statistics on data dictionary, buffer pool, transactions and compression. The optimizer trace exposes query transformations. Enhanced EXPLAIN now supports more statement types and future improvements will provide a structured EXPLAIN output.

2016 oSC MySQL Firewall

Georgi Kodinov

MySQL Firewall is an application level firewall filter that intercepts incoming queries and validates them against a database of normalized "safe" queries. As an integral part of the server it takes advantage of the parsing and normalization that is done anyway so it has minimal impact on normal operations. The firewall has multiple modes. In learning mode it collects the incoming query normalization in a scratchpad that can be persisted to disk. In alert mode it will just alert the DBA for an unknown query but still let it pass. And in protecting mode it will reject all unknown queries. The firewall can be used to limit SQL injection or as a complement to the privilege system to support only particular front end applications. We will go through all of the stages of installing, training and arming the MySQL firewall with understandable examples.

Scaling MySQl 1 to N Servers -- Los Angelese MySQL User Group Feb 2014

The document discusses various options for scaling MySQL databases to handle increasing load. It begins with simple options like upgrading MySQL versions, adding caching layers, and read/write splitting. More complex and reliable options include using MySQL replication, cloud hosting, MySQL Cluster, and columnar storage engines. Scaling to very large "big data" workloads may involve using NoSQL technologies, Hadoop, and data partitioning/sharding. The key challenges discussed are defining business and technical requirements, planning for high availability, and managing increased complexity.
