If you haven't tried the relatively new Linux Cockpit, you might be surprised at what it can do. It is a user-friendly web-based console that provides some very simple ways to manage Linux systems-- through web. You can use a very simple web to monitor system resources, add or delete accounts, monitor system usage, shut down the system, and perform other tasks. It is also very simple to set up and use.

Although many Linux system administrators spend most of their time on the command line, accessing remote systems using tools such as PuTTY does not always provide the most useful command output. Linux Cockpit provides graphics and easy-to-use forms to view performance and make changes to the system.

Linux Cockpit allows you to view many aspects of system performance and make configuration changes, but the task list may depend on the specific Linux you use. Task classification includes the following:

Monitor system activity (CPU, memory, disk IO, and network traffic)-system

View Syslog entries-Lo

View the capacity of disk partitions-storage

View network activity (send and receive)-network

View user account-account

Check the status of the system service-service

Extract the information of installed applications-applications

View and install available updates (if logged in as root) and restart the system as needed-software updates

Open and use the terminal window-terminal

Some Linux Cockpit installations also allow you to run diagnostic reports, dump the kernel, check SELinux settings, and list subscriptions.
