Linuxsysmonitor Linux system monitor

This project is a personal project. I often communicate with test engineers, engineering implementation engineers, and O & M personnel, and found that the Linux system is not easy to operate and maintain.
There are no other useful tools except SSH and xmanager.
Is it possible to create a visual interface tool without having to input command lines?
For example, you need to set up many things to configure an FTP.
Is it very time-consuming to configure dozens of machines?
If dozens of machines need to check whether the running status of the hardware is very difficult.
Although some open-source Web monitoring methods are available, the functions are incomplete and cannot be clearly understood.
You cannot promptly send an alarm to the Administrator.
There are few preventive measures for hackers and Trojans.
Of course I am not going to do an anti-virus software,
I want the Administrator to discover it, track it at the same time, and find the attack source.
Of course, you can also manually or automatically kill it.
This is a comprehensive application of the tamper-proofing, Process detection and removal, and port query functions.
It can also prevent your system files from being modified, but you do not know.
For example, login backdoor, process hiding...
You also need to be notified to your mobile phone in time. You do not need to keep an eye on monitoring.

Description:
This system is used to monitor and manage your Linux server on the window client.
Features include:
CPU, memory, hard disk, network traffic, and other hardware monitoring;
Process query scanning, port query, tamper-proofing scanning and restoration, firewall management,
