System Monitor

MATE System Monitor gives you a live view of what is happening on your system. You can inspect running processes, monitor hardware resource usage, and check disk utilization — all from a single window.

Tabs

Processes

• Send signals to processes (including SIGKILL to force-quit)
• View the full memory map of a process
• Filter by process name
• Show all processes or only your own

Resources

Displays scrolling graphs for:

• CPU — per-core or combined usage over time
• Memory and swap — current usage and history
• Network — received and sent bytes per second

File Systems

Lists mounted filesystems with device, type, mountpoint, total size, free space, and usage percentage.

System

Shows basic system information: hostname, kernel version, MATE version, installed memory, and CPU model.
