Docker Monitoring is the process by which Docker capabilities are checked and managed. Through the use of containers, Docker is a tool that makes it easier to create, deploy, and run applications. Developers use containers to package up an application with all of its necessary elements, for example, libraries and other dependencies, effectively deploying it as one package. Despite the advantage of a faster deployment, using Docker makes for more complex application architectures that can be difficult to monitor. Thankfully, modern IT monitoring such as Centreon facilitate the monitoring of Docker.
