Most Linux distributions (Fedora in my case) have Glances in their repositories. It can be installed on Windows and other hosts with current versions of Python installed. Glances is cross-platform because it is written in Python. If you read my previous article, some of this information may be familiar, but you should also find some new things here. I mentioned Glances in my article 4 open source tools for Linux system monitoring, but I will delve into it more deeply in this article.

However, Glances also monitors filesystem I/O, network I/O, and sensor readouts that can display CPU and other hardware temperatures as well as fan speeds and disk usage by hardware device and logical volume. All of these tools monitor CPU and memory usage, and most of them list information about running processes (at the very least).

A few years ago, I found Glances, a tool that displays information that none of my other favorites do. For me, these primarily used to be top, atop, and htop.

Sysadmins have many tools to view and manage running processes. their command without further arguments, as inĪfter you've used a Spreadsheet to create a graph to see when your CPU load went through the roof, you can then search this file for the nearest time to see what process has caused it.Ģ2:57:42 up 1 day, 4:38, 4 users, load average: 1.00, 1.26, 1.21Ģ2:57:43 up 1 day, 4:38, 4 users, load average: 0.92, 1.24, 1.21Ģ2:57:44 up 1 day, 4:38, 4 users, load average: 0.92, 1.24, 1.21Ģ2:57:45 up 1 day, 4:38, 4 users, load average: 0.92, 1.24, 1.21Ġ.8 0.5 /usr/lib/gnome-panel/clock-appletĠ.8 0.
