How to Collect Metrics with Metricbeat

In today’s data-driven world, monitoring and analyzing system performance is critical for maintaining optimal operations. Metricbeat, a light-weight shipper from Elastic (Official site), allows you to collect metrics from your servers and ship them to the Elastic Stack.

Prerequisites

Access to a server or environment where Metricbeat will be installed.
Basic understanding of the command line and server management.
