BKJIA is just as important as monitoring network traffic and protecting data and computers. Understanding the most basic network fault diagnosis and troubleshooting skills helps you save time and costs. Each Linux release comes with a large number of command line tools to help you diagnose network problems. In addition, there are many open-source tools that can h

I would like to share with you the following four monitoring tools: htop-interactiveprocessviewer interactive process monitoring. You probably know how to view the real-time process status of your machine. If you do not know, use the top command. to view the command instructions, use mantop. htop as the top extension Linux server. I would like to share with you t

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

Linux system monitoring and diagnostic toolsLinux users may not be unfamiliar with top commands (different system names may be different, such as topas in IBM aix ), it is mainly used to monitor the system's real-time load rate, process resource usage, and other system status attributes. Next let's take a look at the top: (1) system and task statistics: the first eight rows are the overall statistics of the

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

The simplest and most straightforward way to do this is to add the -vv parameter at the start of the memcached to print each client's request and corresponding at the console, which is ideal for development. Another straightforward way to do this is through Telnet, for example: If the server is a native 11211 port, you can usetelnet localhost 11211Log in, and then use stats to view the server status.In addition, the better choice is to use a number of specialized
