Puppet is a widely used configuration management and orchestration tool that simplifies defining, managing, and deploying changes across an entire infrastructure. Developed in 2005 by Luke Kanies, Puppet is written in Ruby and available as both open source and commercial software, with over 30,000 companies using it to deploy and orchestrate their applications. Datadog's integration helps monitor Puppet performance metrics and events, allowing users to track run times, resource changes, failed updates, and other key metrics, and set alerts for potential issues. The integration also enables correlation of Puppet runs with other infrastructure metrics, providing a more comprehensive view of the overall system health. Additionally, Datadog customers can configure Puppet to automatically install and configure the Datadog Agent on nodes, allowing for seamless monitoring and tracking of Puppet performance.
