Prometheus and Grafana – monitoring and alerting

Lenght: 3 days

Overview
During training participants will get familiar with the software for:
●applications and servers monitoring using Prometheus, Thanos and Prometheus exporters
●logs aggregation using Grafana Loki and Promtail
●visualizing metrics using Grafana
This is a „Learn by example” course.
The main purpose is to demonstrate how to install and configure Prometheus, Grafana, Loki
and Thanos on Debian Linux systems and Kubernetes clusters.
Each participant will get access to the infrastructure in the public cloud on which the exercises
are performed.

Audience
This course is appropriate for:
-Network, Systems and Database Administrators
-Infrastructure Monitoring Specialists
-IT Platform Specialists
-DevOps Technicians
-Enthusiasts wanting a better understanding and better visibility of their networks in the home or office
-Someone who is curious and wants a good understanding of what Grafana and Prometheus do and what they’re good at.

Requirements or prerequisites
-Basic Linux experience,
-Basic Docker experience,
-All commands entered during the lectures are provided in the corresponding resources
