Introduction
In this tutorial we learn how to install carbon-c-relay on CentOS 8.
What is carbon-c-relay
Carbon-like Graphite line mode relay. This project aims to be a replacement of the original Carbon relay. The main reason to build a replacement is performance and configurability. Carbon is single threaded, and sending metrics to multiple consistent-hash clusters requires chaining of relays. This project provides a multithreaded relay which can address multiple targets and clusters for each and every metric based on pattern matches.
We can use yum or dnf to install carbon-c-relay on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install carbon-c-relay.
