With the continuous development of the Internet industry, a variety of monitoring tools are countless. Here is a list of the most complete monitoring tools on the Web. So you can have more than 80 ways to manage your machine. In this article, we mainly include the following:
Monitoring and debugging performance issues is a daunting task, but sometimes it's easy to use the right tools. Here are some of the tools you may have heard of, or you may not have heard of it-why not try it now?
Eight system monitoring tools1. Top
This is a gadget that is preinstalled on many UNIX systems. When you want to see the processes or threads running in the system: Top is a great tool. You can sort these processes in different ways, which are sorted by CPU by default.
2. htop[1]
Htop is essentially an enhanced version of top. It is easier to sort the processes. It seems to be easier to understand, and there are many common operations built into it. It is also fully interactive.
3. atop[2]
Atop and Top,htop are very similar, but they can also monitor all processes, but unlike top and htop, it can be used for later analysis by logging the log of the process daily. It can also show resource consumption for all processes. It also highlights resources that have reached critical loads.
4. Apachetop[3]
The Apachetop monitors the overall performance of the Apache network server. It is mainly based on Mytop. It displays the current read process, the number of write processes, and the total number of request processes.
5. Ftptop[4]

6. Mytop[5]
Mytop is a very concise tool for monitoring MySQL threads and performance. It allows you to view the database in real time and which queries are being processed.
7. Powertop[6]
PowerTOP can help you diagnose problems related to power consumption and management It can also help you with power management settings to achieve the most efficient configuration for your server. You can use the TAB key to toggle tabs.
8. Iotop[7]
The iotop is used to check I/O usage and provides you with a top-like interface to display. It shows the rate of reads and writes by column, and each line represents a process. When an interchange or I/O wait occurs, it displays the percentage of time that the process consumes.
Network-related monitoring
9. Ntopng[8]
Ntopng is an upgraded version of NTOP, which provides a graphical user interface that can be monitored via a web browser. It also has other uses, such as geo-location hosts, which show network traffic and IP traffic distribution and can be analyzed.
Ten. Iftop[9]
Iftop is similar to top, but it is primarily not checking CPU usage but listening for traffic on the selected network interface and displaying the current usage in tabular form. Like "Why is my internet speed so slow?!" "It's a question that can be answered directly.
