What is Grafana?

Description

Prometheus is a free software application used for event monitoring and alerting. It records real-time metrics in a time series database (allowing for high dimensionality) built using a HTTP pull model, with flexible queries and real-time alerting.

The project is written in Go and licensed under the Apache 2 License, with source code available on GitHub, and is a graduated project of the Cloud Native Computing Foundation, along with Kubernetes and Envoy.

Architecture

A typical monitoring platform with Prometheus is composed of multiple tools:

  • Multiple exporters that typically run on the monitored host to export local metrics.
  • Prometheus to centralize and store the metrics.
  • Alertmanager to trigger alerts based on those metrics.
  • Grafana to produce dashboards.
  • PromQL is the query language used to create dashboards and alerts.
