How To Install collectd on CentOS 8
collectd is Statistics collection daemon for filling RRD files
Introduction
In this tutorial we learn how to install collectd on CentOS 8.
What is collectd
collectd is a daemon which collects system performance statistics periodically and provides mechanisms to store the values in a variety of ways, for example in RRD files.
We can use yum or dnf to install collectd on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install collectd.
Install collectd on CentOS 8 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
The output should look something like this:
CentOS Linux 8 - AppStream 43 kB/s | 4.3 kB 00:00
CentOS Linux 8 - BaseOS 65 kB/s | 3.9 kB 00:00
CentOS Linux 8 - ContinuousRelease 43 kB/s | 3.0 kB 00:00
CentOS Linux 8 - Extras 23 kB/s | 1.5 kB 00:00
