10 BEST Kubernetes monitoring tools
Kubernetes is a production-ready, open-source platform designed with Google’s accumulated experience in container orchestration, combined with best-of-breed ideas from the community. It is designed to automate deploying, scaling, and operating application containers.
With the increasing adoption of containers and microservices in the enterprises, monitoring utilities have to handle more services and server instances than ever before. Although infrastructure landscape has changed, operations teams still need to monitor the same metrics on CPU, RAM, File System, Network utilization, and the availability of service endpoints. In this post, we take look at some of the best monitoring tools available for Kubernetes.

New Relic Infrastructure on-host integration for Kubernetes, provides deep monitoring of the container orchestration layer. It collects metrics that monitor data and metadata for nodes, Namespaces, Deployments, ReplicaSets, Pods, and containers, so you can fully monitor your frontend and backend applications and hosts running in your Kubernetes clusters.
- Comprehensive view of the health of your servers and hosts as well as the applications and services
- Cloud-ready out-of-the-box integrations let you view and report data from various services
- Detailed views of the processes running within containers and track container versions.
- Full visibility into how your host is performing, sorted by the host traits you care about. Infrastructure collects and displays health metrics such as CPU, Load, Memory, etc. at the host level, as well as individual Process, Network, and Storage level.
- Tag-driven alerting and dashboarding
- Powerful search allows you to find vulnerable packages and other inventory items
To activate on-host integration, deploy the
newrelic-infra agent onto a Kubernetes cluster. Check out documentation on Kubernetes integration here.
Be it traditional or microservice-based applications running on Kubernetes. AppDynamics for Kubernetes offers a unified solution to deliver flawless application experiences.
- Visibility into Kubernetes by leveraging labels like Namespace, Pods, ReplicaSets, Deployment, or any other Kubernetes label. Organize, group, query, or filter Kubernetes objects or performance metrics based on labels
- Consistent visibility into Kubernetes clusters deployed across on-premises or hybrid environments
- Quickly triage the root cause via stack-ranked order of potential root causes
- Isolate the performance issues in different environments and their impact on business in real-time.
To install AppDynamics for Kubernetes visibility follow these steps :
- Install a Standalone Machine Agent in a Kubernetes node.
- Install an APM Agent inside each container in a pod that needs to be monitored.
- The Standalone Machine Agent then collects hardware metrics for each monitored container, as well as Machine and Server metrics for the host, and forwards the metrics to the Controller.
Linkerd is a service sidecar and service mesh for Kubernetes and other frameworks. It gives you runtime debugging, observability, reliability, and security–all without requiring any changes to your code.
Linkerd has three basic components: User interface, data plane, and a control plane. Linkerd works by installing ultralight proxies into each pod of a service. These proxies become part of a data plane which reports telemetry data to, and receives signals from, a control plane.
- Automatically instruments metrics such as request volume, success rates, and latency distributions.
- Provides real-time streams of the requests for all incoming and outgoing traffic.
- Linkerd proxy natively exports Prometheus metrics.
Linkerd control plane must be installed first and then add the data plane proxies for respective services. Checkout Documentation for more details on how to install/configure for Kubernetes.

Weave Scope is a visualization and monitoring tool for Docker and Kubernetes. For Microservices-based architecture, Weave scope would be useful in visualizing network bottlenecks, troubleshooting CPU consumption, and troubleshooting memory leaks. It provides a top-down view into your app as well as your entire infrastructure and allows you to diagnose any problems with your distributed containerized app, in real-time, as it is deployed to a cloud provider.
- Drill down Views: For an app that is running in Kubernetes, Scope displays Pods, Replica Sets, Deployments, and related Services on clusters. So for containerized microservices running in the cloud, you can view Processes, Containers, Orchestrators, and Hosts.
- Real-time Contextual metrics: By clicking on a node you can get a detailed panel with additional metrics on the node. From the detailed panel, you can drill down on processes inside your container to the hosts that your containers run on.
- Troubleshoot / Manage Containers: On clicking of a container, pod or host, you can view the controls pane from there you can pause, restart, stop and delete without having to leave the Scope browser window. If further troubleshooting is required, terminal windows can be launched from any container or host so that you can interact with your app and run any UNIX command to diagnose issues.
- Search: Weave supports simple operands so that for example, you can find processes consuming a certain amount of memory or nodes using too much CPU.
- Filtering options: Nodes can be filtered by CPU and Memory usage so that you can easily find containers using the most resources. If you are running an app in Kubernetes then your app can be filtered by namespace and by container state whether running or stopped or contained and uncontained.
- Graphic / Table Mode: Views can be presented in Graphic as well as Table Mode. The graphical mode is more useful in cases where you want to have a quick visual overview of your app. Tablet mode is for viewing data like resources being consumed by processes, containers, and hosts, etc.,
