What is DODBA tools?DODBA Tools is a console-based remote monitoring tool that does not need to install any software on the local/remote system, it collects real-time performance status data of the operating system, MySQL, InnoDB in real time, and can generate doing log files to help you quickly understand/ Optimized system and MySQL database.Characteristics:

The JDK provides us with a range of JVM performance monitoring and troubleshooting tools, which are documented here based on learning progress.

When it comes to locating the system, we often need to understand and analyze the runtime state of the JVM. What should be the starting point? The answer is to start with the data. The data here include: GC logs, exception stacks, thread snapshots (threaddump), heap dump snapshots (heapdump), and so on. The JDK is built with a wealth of virtual machine monitoring and analysis tools to use. Can make our trou

A fully running Linux system consists of many subsystems (introduction, Cpu,memory,io,network, ...). ), monitoring and evaluating these subsystems is part of the performance monitoring. We often need macroscopic view of the whole system state, also need microscopic look at the operation of each subsystem. Fortunately, we don't have to reinvent the wheel to monitor these subsystems with the
