Glances is a text-based monitor that gives details about:

- Community interface
- Disk I/O
- IRQ / Raid
- Filesystem (and folders)
- System data
- Quicklook (CPU, MEM, LOAD)
Glances even features a web-based GUI that makes monitoring much more versatile. Let’s set up and use Glances on Ubuntu Server 18.04 (concern not, Glances might be put in on most distributions, from the usual repository).
