Find and use your Kubernetes data

You can build your own charts and query all your Kubernetes integration data using the query builder and the NerdGraph API. Our integration collects Kubernetes data by instrumenting the container orchestration layer. For a simpler and more visual experience, use the cluster explorer.

one.newrelic.com > Dashboards: Using the query builder you can query your Kubernetes data and create clear visualizations.

Query Kubernetes data

The simplest way to query your Kubernetes data is using the query builder, which accepts NRQL queries. Alternatively, you can use the NerdGraph API to retrieve Kubernetes data.
