Kubernetes events integration

The New Relic Kubernetes events integration watches for events happening in your Kubernetes clusters and sends those events to New Relic. To visualize your event data, use the Kubernetes cluster explorer, or use the infrastructure events UI.

Installation

The Kubernetes events integration is installed by default both when using our Guided Install, or when installing through Helm.

View your Kubernetes events

Once you've successfully installed the Kubernetes event integration, you can view and query your events in New Relic.

To add events to your dashboard:

1. Add a chart to a new or existing dashboard or create a chart using the New Relic query builder.

2. When creating or updating your chart, select the chart type table and use the following event query, replacing YOUR_CLUSTER_NAME with the name of your cluster:

   FROM InfrastructureEvent SELECT
   event.involvedObject.kind, event.involvedObject.name, event.reason,event.message
   WHERE clusterName = 'YOUR_CLUSTER_NAME' limit 100

   Copy

Query events

Here are a few examples to query your data:

Get attributes names

To see all the attributes names, use the following query:

FROM InfrastructureEvent SELECT keyset() WHERE category = 'kubernetes'

See event details

To see details about the latest events in a cluster, use the following query, replacing YOUR_CLUSTER_NAME with the name of your cluster:

FROM InfrastructureEvent SELECT event.involvedObject.kind,
event.involvedObject.name, event.type, event.message, event.reason WHERE
category = 'kubernetes' AND clusterName = 'YOUR_CLUSTER_NAME'

The events collected by New Relic will have the exact same attributes as given by Kubernetes. For a reference of these attributes, see the Kubernetes event v1 core documentation.

Search events in New Relic

To search events in the New Relic Infrastructure UI:

1. Navigate to the Infrastructure event page: Go to one.newrelic.com > Infrastructure > Events.
2. In Category, select kubernetes.
3. Use the Search events field to look for specific events. To focus on a specific set of events, select or change the filter set.

View events in the Kubernetes cluster explorer

To view events in the Kubernetes cluster explorer, use either of these methods:

• In New Relic: Go to one.newrelic.com > Kubernetes cluster explorer.

Then, to view the pod details:

1. In the Kubernetes cluster explorer, select a pod.
2. Select Show pod events.

Optional: Collect metrics of the event collector

To collect metric data for the event collector itself, install the New Relic Prometheus agent integration. To get started:

1. Install the New Relic Prometheus agent integration.
2. Label the deployment of your Kubernetes events integration with your configured scrape label (default is prometheus.io/scrape=true).

Optional: Define custom attributes

To add custom attributes to the events sent by the integration these need to be specified in your values.yaml under the customAttributes map.

For example, to add the attribute environment with value dev to all the events, add the following to your values.yaml:

nri-kube-events:
  customAttributes:
    environment: dev

You can add other custom attributes globally to all other kubernetes integrations by setting it globally:

global:
  customAttributes:
    environment: dev
