Kubernetes Monitoring
Introduction to Kubernetes
Kubernetes (also known as K8s) is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. It was originally developed by Google and is now maintained by the Cloud Native Computing Foundation (CNCF).
Kubernetes allows developers to deploy, manage, and scale containerized applications across a cluster of nodes, providing features such as load balancing, automatic scaling, self-healing, and rolling updates. It provides a declarative way to define the desired state of an application and ensures that the actual state matches the desired state.
Kubernetes is highly modular and extensible, with a large ecosystem of plugins and tools that can be used to customize and extend its functionality.
OpsPilot brings AI-powered Kubernetes monitoring giving SREs, application developers, and DevOps administrators deep visibility into cluster health, workload performance, and reliability - with autonomous detection of issues and AI-guided investigation to cut resolution time.

Kubernetes integration
These pages cover shipping cluster metrics with the Kube-Prometheus-Stack chart. OpsPilot also offers a Kubernetes integration that installs the dashboards, recording rules, and alerts and collects metrics with the Grafana Kubernetes Monitoring chart - the simplest path for most clusters. Use whichever chart you already run or prefer.
Benefits
-
Real time alerts. Monitoring Kubernetes clusters in real-time can detect errors early and send alerts to you immediately. This saves your brand's reputation and reduces service restoration time.
-
Workload optimization. Monitoring your Kubernetes cluster can help you manage workloads better and optimize resource usage. This can lead to better performance and reliability.
-
Troubleshoot with ease. Monitoring can assist in troubleshooting by accessing logs and discovering root causes of issues. This can minimize downtime and reduce the workload for developers.
-
Real time visibility. Monitoring your Kubernetes cluster helps you track costs in real-time. It lets you see how many nodes, load balancers, and persistent volumes are deployed and the cost incurred from each.
-
Powerful insights. Kubernetes monitoring provides unique insights into how users interact with your application, helping you improve future product decisions. It also helps in identifying features that need expansion or improvement.
Clusters or pods?
A Kubernetes cluster and a pod are two different concepts in Kubernetes architecture.
A Kubernetes cluster is a group of nodes that work together to run containerized applications. The cluster consists of a master node that manages the cluster, and one or more worker nodes that run the containers. The master node is responsible for scheduling containers, monitoring their health, and managing their lifecycle. The worker nodes are where the containers actually run and execute their processes. The cluster provides a high-level abstraction for managing and scaling containerized applications, and provides features such as load balancing, service discovery, and automatic failover.
A pod, on the other hand, is the smallest deployable unit in Kubernetes. It is a logical host for one or more containers, and represents a single instance of a running process. Pods are used to encapsulate and manage the runtime environment for a container, including its network and storage resources. Multiple containers can be co-located within a pod and share the same network namespace, allowing them to communicate with each other using localhost.
In summary, a Kubernetes cluster is a group of nodes that work together to run containerized applications, while a pod is the smallest deployable unit in Kubernetes that represents a single instance of a running process and encapsulates the runtime environment for one or more containers.
Kubernetes dashboards
Kubernetes monitoring with OpsPilot includes a full set of dashboards out of the box, so you can observe your clusters and workloads straight away - whether they run on-premises or in the cloud.
The set covers compute resources and networking at multi-cluster, cluster, namespace, node, pod, and workload levels (with Windows variants), the control plane (API server, Controller Manager, Kubelet, Scheduler, Proxy), Persistent Volumes, and USE Method dashboards.
Find them in OpsPilot > Dashboards > Kubernetes.
