How to monitor the system in Linux Mint?

To monitor the system in Linux Mint, you can use various tools and commands that provide real-time information about the system's performance, resource usage, and overall health. Here are some methods:

1. System Monitor

Linux Mint comes with a built-in tool called "System Monitor" which provides a graphical interface to monitor CPU, memory, network, and disk usage.

• How to Access:
  • Open the "System Monitor" from the Applications menu or by searching for it in the dashboard.
• Features:
  • Displays CPU, memory, network, and disk usage in real-time.
  • Shows running processes and their resource consumption.

2. Terminal Commands

Several terminal commands can be used to monitor system performance:

• top:

  • Shows real-time CPU and memory usage.
  • Example: Open a terminal and type top.

• htop:

  • An advanced version of top with a more user-friendly interface.
  • Install using sudo apt-get install htop and then run htop.

• vmstat:

  • Reports virtual memory statistics.
  • Example: vmstat 1 to update every second.

• iostat:

  • Provides statistics on CPU usage and I/O devices.
  • Example: iostat -x 1 to update every second.

3. System Logs

Monitoring system logs can provide insights into potential issues and system behavior.

• journalctl:
  • Views logs from the systemd journal.
  • Example: journalctl -xe for extended output.

4. Network Monitoring

For network monitoring, tools like iftop and nethogs can be useful.

• iftop:
