If you’re in a DevOps, Cloud or SRE role, you’ll understand how important monitoring & alerting is. You cannot build a successful application, or run a company without having a system that monitors your systems and applications and reports when something goes wrong. You need instrumentation in order to be successful.
Prometheus is the leading open-source monitoring system that can collect metrics from all your systems, including Linux servers, Windows Servers, Database Servers and any application you have written. It’s inspired on Google’s Borgmon, which uses time-series data as a datasource, to then send alerts based on this data.
This course will show you how to install and configure Prometheus on a Linux server. This course will use a VM on DigitalOcean, but you can install Prometheus on any modern Linux OS. We’ll show you how to make visualizations (graphs) using Grafana. When building these graphs, you’ll get to know PromQL, the language to query Prometheus and get meaningful data displayed. You’ll also learn how to setup alerts to receive notifications when something goes wrong. Lastly, we have a section on use-cases to showcase you some real world examples.
