5. Node Monitoring

Installation of Node Monitoring

In this chapter, we will walk you through the setup of local monitoring for your collator node.

Installation

Make sure you download the latest releases. Please check Prometheus, Process exporter, and Grafana download pages. We will continue to update this guide but recommend that you verify that you are installing the latest versions.

There are 7 steps to install these packages:

• Download
• Extract
• Move the files to /usr/lib/bin
• Create dedicated users
• Create directories
• Change the ownership of those directories
• Cleanup
