Alerting on Issues with Prometheus Alertmanager

Brought by: Pluralsight

Overview

Alerts are an important way to keep your system running. This course will teach you how to configure Prometheus Alertmanager. You'll learn to send alerts through email and slack, as well as management strategies for grouping and silencing alerts.

It’s great to have monitoring set up, but how can you keep alerts meaningful? Too many and people start to ignore them - too few and you may miss things that need to be fixed. In this course, Alerting on Issues with Prometheus Alertmanager, you’ll learn to manage alerts in a way that makes sense for your situation. First, you’ll explore alerting principles and set up the Alertmanager application. Next, you’ll discover receivers and how to use them to send alerts through different channels like email and instant messaging. Finally, you’ll learn how to effectively manage your alerts with features like grouping related alerts and silencing duplicates. When you’re finished with this course, you’ll have the skills and knowledge of alerting needed to configure Alertmanager in a way that makes sense for your situation and adds value to your organization.
