Yahoo! MySQL Performance Analyzer: In-depth exploration of database performance

This article will explore in-depth Yahoo! MySQL Performance Analyzer, a powerful tool that comprehensively analyzes the performance of MySQL databases, including real-time monitoring and detailed reporting, so as to efficiently identify and resolve performance issues.

Main advantages:

• Comprehensive Analysis: Provides a comprehensive analysis of the performance of MySQL databases, covering real-time monitoring and detailed reporting.
• User-friendly: The interface is intuitive and easy to use, and even non-professionals can easily get started.
• Widely compatible: Supports multiple MySQL versions and is able to handle large databases.
• Core features: Includes database metadata browsing, query analysis, and user-defined alert settings based on predefined metrics or database queries.

Installation and configuration:

Analyzer uses SNMP when it is available, so it is best to install SNMP on the database server. Since this is a Java application, make sure you have JDK 8 installed before continuing (JDK 7 is also OK, but will not use any of JDK 8's features).

The following steps demonstrate the process of installing the analyzer on a Vagrant virtual machine:

1. Login to your virtual machine via SSH.
2. Clone GitHub repository: git clone git@github.com:yahoo/mysql_perf_analyzer.git myperf
3. Runmvn clean packageBuild the application.
4. Unzip the generated myperfserver-server.zip file to a new directory on the server.
5. Use the start_myperf.sh script to start the application.

User Management and Dashboard:

After starting the server, open browser access using the host name and the specified port (for example: vaprobash.dev:9092/myperf). Default administrator account (username: myperf, password: change).

The main dashboard displays the current status of the database and other detailed information such as CPU usage, running threads, deadlocks, etc. The second tab shows alerts for the past 24 hours.

Database group configuration, process monitoring and diagrams:

You can create new database groups to monitor a single or multiple databases. The "Top" page provides real-time monitoring of system resources, similar to the Linux top command.

The Charts tab provides charting tools for comparing the performance of database servers over time.

Database metadata browsing, query explanation and alerts:

Analyzer provides an easy way to browse database and table metadata such as columns, views, indexes, triggers, etc.

Alarm function allows you to set rules to define when (or will) problems occur in the system. You can create alerts using predefined metrics or database queries.

Summary:

This article briefly introduces the main functions of Yahoo! MySQL performance analyzer. The project is still under development. You are welcome to contribute code on GitHub. A subsequent article will introduce more advanced usage of using the analyzer in a real database environment.
