New Relic integration for Kubernetes

New Relic's Kubernetes integration gives you full observability into the health and performance of your environment, no matter whether you run Kubernetes on-premises or in the cloud. It gives you visibility about Kubernetes namespaces, deployments, replica sets, nodes, pods, and containers. Metrics are collected from different sources:

• kube-state-metrics service provides information about state of Kubernetes objects like namespace, replicaset, deployments and pods (when they are not in running state)
• /stats/summary kubelet endpoint gives information about network, errors, memory and CPU usage
• /pods kubelet endpoint provides information about state of running pods and containers
• /metrics/cadvisor cAdvisor endpoint provides missing data that is not included in the previous sources.
• /metrics from control plane components: ETCD,controllerManager, apiServer and scheduler

Check out our documentation in order to find out more how to install and configure the integration, learn what metrics are captured and how to query them.

Installation

Start by checking the compatibility and requirements and then follow the installation steps.

For troubleshooting, see Not seeing data or Error messages.

Helm chart

You can install this chart using nri-bundle located in the helm-charts repository or directly from this repository by adding this Helm repository:

helm repo add nri-kubernetes https://newrelic.github.io/nri-kubernetes
helm upgrade --install nri-kubernetes/newrelic-infrastructure -f your-custom-values.yaml

For further information of the configuration needed for the chart just read the chart's README.

Usage

Learn how to find and use data and review the description of all captured data.

Running the integration against a static data set

• See cmd/kubernetes-static/readme.md for more details regarding running the integration.
• See internal/testutil/datagen/README.md for more details regarding generate new data.

Development

Run e2e Tests

• See e2e/README.md for more details regarding running e2e tests.

Tests

For running unit tests, run

make test

Run local development environment

We use Minikube and Tilt to spawn a local environment that it will reload after any changes inside the charts or the integration code.

Make sure you have these tools or install them:

• Install minikube
• Install Tilt
• Install Helm

Create a values-local.yaml file from the values-local.yaml.sample using a valid license key and your cluster name.

Start the local environment:

make local-env-start

Notice that local images are build and pushed to docker running inside the minikube cluster since we are running eval $(minikube docker-env) before launching Tilt.

Note: when running the local-dev-environment with a Kubernetes cluster < v1.21, you will need to remove the apiVersion templating for the CronJob resource and manually set apiVersion: batch/v1beta1. This is because Tilt uses helm template and helm template doesn't render capabilities: https://github.com/helm/helm/issues/3377.

Running OpenShift locally using CodeReady Containers

• See OpenShift.md for more details regarding running locally OpenShift environments.

Support

Should you need assistance with New Relic products, you are in good hands with several support diagnostic tools and support channels.

New Relic offers NRDiag, a client-side diagnostic utility that automatically detects common problems with New Relic agents. If NRDiag detects a problem, it suggests troubleshooting steps. NRDiag can also automatically attach troubleshooting data to a New Relic Support ticket. Remove this section if it doesn't apply.

If the issue has been confirmed as a bug or is a feature request, file a GitHub issue.

Support Channels

• New Relic Documentation: Comprehensive guidance for using our platform
• New Relic Community: The best place to engage in troubleshooting questions
