The Cluster receiver is a 1-replica deployment of the OpenTelemetry Collector. Because the Kubernetes control plane can select any available node to run the cluster receiver pod (unless ``clusterReceiver.nodeSelector`` is explicitly set to pin the pod to a specific node), ``hostPath`` or ``local`` volume mounts don't work for such environments.

Data persistence is currently not applicable to the Kubernetes cluster metrics and Kubernetes events.

Monitor OpenShift infrastructure nodes
============================================

By default, the Splunk Distribution of OpenTelemetry Collector for Kubernetes doesn't collect data from OpenShift infrastructure nodes.

You can customize the Collector Helm Chart file to activate data collection from OpenShift infrastructure nodes. To do so, complete the following steps:

#. Open your values.yaml file for the Helm Chart.
#. Copy and paste the following YAML snippet into the values.yaml file:

.. code-block:: yaml

tolerations:
- key: node-role.kubernetes.io/master
effect: NoSchedule
- key: node-role.kubernetes.io/control-plane
effect: NoSchedule
- key: node-role.kubernetes.io/infra
effect: NoSchedule
operator: Exists

#. Install the Collector using the Helm Chart:

.. code-block:: bash

helm install my-splunk-otel-collector --values values.yaml splunk-otel-collector-chart/splunk-otel-collector

.. note:: Monitoring OpenShift infrastructure nodes might pose a security risk depending on which method you used to create the Kubernetes environment.
