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.

Manage alerts

You can be notified about alert violations for your Kubernetes data:

To create an alert condition for the Kubernetes integration:

Go to one.newrelic.com > Infrastructure > Settings > Alerts > Kubernetes, then select Create alert condition.
To filter the alert to Kubernetes entities that only have the chosen attributes, select Filter.
Select the threshold settings. For more on the Trigger an alert when... options, see Alert types.
Select an existing alert policy, or create a new one.
Select Create.
When an alert condition's threshold is triggered, New Relic sends a notification to the policy's notification channels.

The Kubernetes integration comes with its own alert policy and alert conditions. To see what the predefined alert conditions are, see Kubernetes integration: Predefined alert policy.

In addition, you can create an alert condition for any metric collected by any New Relic integration you use, including the Kubernetes integration:

Select the alert type Integrations.
From the Select a data source dropdown, select a Kubernetes (K8s) data source.

When an alert condition's threshold is triggered, New Relic sends a message to the notification channel(s) chosen in the alert policy. Depending on the type of notification, you may have the following options:

View the incident.
Acknowledge the incident.
Go to a chart of the incident data by selecting the identifier name.
The entity identifier that triggered the alert appears near the top of the notification message. The format of the identifier depends on the alert type:
Available pods are less than desired pods alerts:
```
K8s:CLUSTER_NAME:PARENT_NAMESPACE:replicaset:REPLICASET_NAME
```
CPU or memory usage alerts:
```
K8s:CLUSTER_NAME:PARENT_NAMESPACE:POD_NAME:container:CONTAINER_NAME
```
Here are some examples.
For Available pods are less than desired pods alerts, the ID of the ReplicaSet triggering the issue might look like this:
k8s:beam-production:default:replicaset:nginx-deployment-1623441481
This identifier contains the following information:
Cluster name: beam-production
Parent namespace: default
ReplicaSet name: nginx-deployment-1623441481
For container CPU or memory usage alerts, the entity might look like this:
k8s:beam-production:kube-system:kube-state-metrics-797bb87c75-zncwn:container:kube-state-metrics
This identifier contains the following information:
Cluster name: beam-production
Parent namespace: kube-system
Pod namespace: kube-state-metrics-797bb87c75-zncwn
Container name: kube-state-metrics
