How to install Glances on CentOS 7?

We already know that monitoring your server is something basic like sysadmin. But it is not only limited to those professionals in server administration but we can do it ourselves. For it, they count on diverse light tools and open source that, they help us with it. In addition, we like monitoring because it helps to be attentive to any eventuality that arises in the computer. So, that’s why today I’ll show you how to install Glances on CentOS 7.

Glances is a cross-platform system monitoring tool written in Python. Glances helps us keep an eye on our system, just the website project says.

Among its main features, we have that it is possible to choose to display system information on the terminal or remotely through a web interface. It also has an API that allows third-party applications to use Glances.

Some of the parameters that Glance allows you to monitor are there:

  • CPU.
  • Memory.
  • Load.
  • Process list.
  • Network interface.
  • Disk I/O.
  • IRQ / Raid.
  • Sensors.
  • Filesystem (and folders).
  • Docker.
