Kubernetes monitoring is the process of gathering metrics from the Kubernetes clusters you operate to identify critical events and ensure that all hardware, software, and applications are operating as expected. Monitoring is essential to provide insight into cluster health, resource consumption, and workload performance. With the right monitoring, errors that occur in any layer of the stack can be quickly identified and corrected.
There are many Kubernetes monitoring tools, including open-source tools like Prometheus and the ELK Stack as well as commercial tools including Datadog, Cloudwatch, and New Relic.
