Advantages of Prometheus
Advantages of Prometheus compared to other Monitoring tools are listed as following:
- An important characteristic of Prometheus is that it is designed to be reliable even when other systems have an outage so that you can diagnose the problems and fix them.
- Each Prometheus server is standalone and self containing meaning it doesn’t depend on network storage or other remote services.
- Prometheus always works, even if other parts of the infrastructure are broken. You do not have to install agents, your Prometheus installation can already pull metrics.
- You do not need to set up extensive infrastructure to Prometheus Server.
- Prometheus is fully compatible with both Docker and Kubernetes and Prometheus components are available as Docker images and therefore can easily be deployed in Kubernetes or other container environments.
- It integrates great with Kubernetes infrastructure providing cluster node resource monitoring out of the box which means once it’s deployed on Kubernetes it starts gathering matrix data on each Kubernetes node server without any extra configuration.
Kubernetes Prometheus
With modern DevOps becoming more and more complex, monitoring and alerting stakeholders has become even more crucial for any microservice, and Prometheus is a tool to do the same. Prometheus is a completely open-sourced tool created to monitor highly dynamic container environments like Kubernetes, Docker Swarm, etc. However, it can also be used in a traditional non-container infrastructure where you have just bare servers with applications deployed directly on them. In this article, we will learn what prometheus is. We will see why Prometheus is so important in such infrastructure. And what are some of its use cases?
