Picking up the right Kubernetes Monitoring Tools can be a challenging task. We compiled this list of the best K8 Monitoring Tools (with detailed reviews) to ease your work.

Kubernetes is quickly becoming the standard for container orchestration, allowing developers to deploy and manage applications quickly and easily in a distributed environment.

However, managing and monitoring K8s can be challenging because a Kubernetes cluster appears to be a single computer to a user, but it is actually a set of independent nodes and multiple services that have been connected.

To properly monitor and observe a Kubernetes cluster, you will need to change your monitoring and observability strategies and tools.

Here are some of the most popular and reliable Kubernetes monitoring tools you can use in 2024.

What are Kubernetes Monitoring tools?

Kubernetes monitoring tools are software solutions designed to monitor the health, performance, and availability of Kubernetes clusters and the applications running on them.

These tools provide insights into various aspects of the Kubernetes environment, such as resource utilization, pod status, network traffic, and application metrics.

Best Kubernetes monitoring tools and why you need them

Kubernetes is a complicated system that needs careful cluster monitoring tools to spot and troubleshoot production-related problems. You can efficiently monitor your deployments in production with the aid of these paid Kubernetes monitoring tools.

2. Prometheus: Best free K8s monitoring tool

One of the most often used Kubernetes monitoring tools is Prometheus. It is a part of the Cloud Native Computing Foundation and is community-driven. Google Borg Monitor served as the basis for this project, which was first created by SoundCloud and then contributed to the CNCF.

Prometheus stores all of its data as a time series. The PromQL query language can query this data, and an expression browser is built-in to visualize it. Grafana is used by Prometheus since it lacks a dashboard and needs to visualize data.

Logs can be gathered and processed by Logstash before being sent to be stored. Elasticsearch will function well even when storing and searching through millions of pages because it was built to be scalable. Kibana covers the analysis interface required by users to interpret the data.

What should you be monitoring in Kubernetes?

To maintain Kubernetes security, you can monitor various KPIs. These are typically divided into three primary categories: resource monitoring, services monitoring, and infrastructure monitoring.

Infrastructure performance

You must monitor the metrics below to determine how well your Kubernetes infrastructure performs.

CPU usage

You may gain valuable insight into cluster performance by monitoring the amount of CPU your pods are using with regards to their configured requests and limitations, as well as CPU utilization at the node level. A lack of available CPU at the node level can cause the node to restrict the amount of CPU allotted to each pod, much as a pod exceeding its CPU limits.

Kubernetes Resource Metrics View - Datadog

Disk usage

Disk space is a non-compressible resource, just like RAM; hence scheduling issues with pods may arise if a Kubelet detects low disc space on its root volume. A node will be marked as being under disc pressure if its remaining disc capacity exceeds a predetermined resource threshold. You should monitor the amounts of volume usage used by your pods besides node-level disc utilization. You can avoid issues at the application or service level by doing this.

Pod resources

Resource requests and limits, along with resource consumption, will provide you with a more detailed analysis of your cluster’s ability to handle existing workloads and accept new ones. It’s critical to monitor resource utilization throughout your cluster, especially for your nodes and the pods they support.


The best KPIs for identifying microservice concerns quickly are those related to APIs, like request rate, call error, and latency. These matrices make it easy to find degradations in a microservice component.

Automatic detection of REST API request irregularities makes it simple to find service-level metrics. These metrics provide uniform visibility across the clusters by measuring each Kubernetes service in the same way.


To evaluate whether the cluster is underutilized or at capacity, monitor how the infrastructure and resources are used. It is crucial to keep track of node health and availability to determine whether there are enough resources and nodes accessible to replicate applications. Finally, monitor resource or chargeback utilization for each project or team.

Why monitoring Kubernetes is Important?

Proactive cluster management is made possible with the aid of Kubernetes monitoring, a type of reporting. Cluster monitoring tools make it easier to manage containerized infrastructure by keeping track of how memory, CPU, and storage are being used. When the required number of pods is not operating, resource usage is about to reach critical levels, or misconfiguration prevents nodes or pods from joining the cluster, cluster operators can monitor and get alerts.

The rapid adoption of containers in enterprise-level enterprises has benefited IT teams, DevSecOps teams, and developers globally in several ways. However, Kubernetes’ flexibility and scalability in the deployment of containerized apps also introduce additional difficulties. Without the right Kubernetes monitoring tools, it’s difficult to monitor the health of apps that have been abstracted by containers and then again by Kubernetes because there is no longer a 1-to-1 correlation between an application and the server it runs on.

1. Reliability and troubleshooting

One of the best ways to foresee issues and identify bottlenecks in a production setting is to monitor an application’s condition continuously. Cluster operators in Kubernetes monitor the cluster and provide alerts when the number of pods is running, resource consumption is getting dangerously close to a critical limit, or a failure or configuration mistake stops a pod or node from joining the cluster.

Many businesses employ specific cloud-native K8s monitoring tools to get complete visibility over cluster activity besides this built-in monitoring functionality.

2. Kubernetes performance tuning

Data on the number, condition, and accessibility of different Kubernetes objects, such as pods, are released by the Kubernetes API server. Internal Kubernetes processes and components use this data to monitor whether pods are launched, maintained, and correctly scheduled for new pods.

You may get a high-level overview of your cluster’s state using these cluster state metrics. They can reveal problems with nodes or pods, alerting you to the likelihood that you need to scale back your cluster or look into a bottleneck.

3. Cost management 

You can identify what services cost your company the most by checking that resources in your Kubernetes cluster are properly tagged using labels or namespaces. Monitoring is frequently the best place to start when figuring out the return on investment of various cost-cutting measures.

Setting up an overall framework is highly advised. You must make sure that you are informed if anything unusual occurs. For instance, you’ll want to be informed if a product or service unexpectedly increases in price so that you may investigate the cause and implement changes.

4. Security

By actively monitoring clusters, containers, and namespace resource allocation, Kubernetes monitoring can assist you in enhancing security. You can monitor a variety of KPIs to maintain Kubernetes security. Kubernetes monitoring tools like Prometheus may monitor some Kubernetes metrics you can use for security. To ensure you don’t miss any security threats, tools like Grafana present metrics on many dashboards.

How to choose the right k8s monitoring tool

Given all the options at your disposal, how can you choose the best tool for your organization? Your organization’s needs will ultimately determine your choice, as was already indicated. It’s crucial to consider both your existing environments and the future state of your Kubernetes while making these choices. To maintain efficient operations and get the most out of your monitoring and analytics, you must select a K8 monitoring strategy that will scale as your business expands.
