Kubernetes Prometheus
What is Prometheus in Kubernetes?
Prometheus in Kubernetes is an open-source monitoring and alerting tool that gathers metrics from Kubernetes clusters, providing insights into system performance and health, enabling efficient monitoring and troubleshooting.
What is Prometheus tool used for?
Prometheus is a monitoring and alerting toolkit used to collect, store, and query time-series data, enabling organizations to monitor the health and performance of their systems and applications in real-time.
Are there any down sights to Prometheus?
One disadvantage that Prometheus has is it that it can be difficult to scale when you have hundreds of servers you might want to have multiple Prometheus servers that somewhere aggregate all this metrics data and configuring that and scaling Prometheus in that way can be very difficult. So while using a Single Node is less complex and you can get started very easily, it puts a limit on the number of metrics that can be monitored by Prometheus.
Where does Prometheus store data in Kubernetes?
Prometheus stores data locally within its containers in Kubernetes, typically in the
/prometheus
directory. Alternatively, Prometheus can be configured to use remote storage solutions like Thanos, Cortex, or VictoriaMetrics for long-term data storage.
Why use Prometheus for Kubernetes?
Prometheus is ideal for Kubernetes monitoring due to its native support for Kubernetes service discovery and dynamic scaling, ensuring seamless monitoring of containerized applications with minimal configuration overhead. Additionally, its rich querying language and robust alerting capabilities enable effective monitoring and troubleshooting in Kubernetes environments.
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?
