Monitoring Linux system performance every day is a daunting task for every system/network administrator. After 5 years of Linux system administrators in the IT industry, I found it's not easy to monitor and keep the system up and running, so I've summed up 8 very useful command-line tools for Linux/unix system administrators. These commands support all Linux systems and can be used not only to monitor the s

In addition to the integrated VISUALVM and Jconsole, the JVM also has small tools such as JPS, Jstack, Jmap, Jhat, Jstat, etc.Problems that may be encountered in development OutOfMemoryError, Low memory Memory leaks Thread deadlock Lock contention (lock contention) The Java process consumes too much CPU These problems may be overlooked by many people in their daily development (for example, some people encounter the probl

For system and network administrators, it is a heavy task to monitor and debug the performance of Linux systems on a daily basis. After 5 years working as an administrator in the IT field as a Linux system, I gradually realized how difficult it was to monitor and keep the system up and running. For this reason, we have written a list of the 18 most commonly used command-line tools that will help each Linux/unix system administrator work. These command

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:

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
