Linux has lot of ways to monitor the system and resources usage. If you are one of those curious persons who would like to know how your system is going, then you are going to love Glances. You can find many monitoring tools that are specific to monitor one aspect of the linux system (disk, ram, cpu, i/o, etc), however Glances is like the classic top command, but it looks better.
Glances will show you monitoring data from kernel, CPU, load average, system process, memory usage, among other things. It is free and open source, written on Python and is available on most modern linux distributions.
We are going to install Glances on CentOS Linux using EPEL repo.
