Red Hat Summit24장. Using the Node Observability Operator
The Node Observability Operator collects and stores CRI-O and Kubelet profiling or metrics from scripts of compute nodes.
With the Node Observability Operator, you can query the profiling data, enabling analysis of performance trends in CRI-O and Kubelet. It supports debugging performance-related issues and executing embedded scripts for network metrics by using the run field in the custom resource definition. To enable CRI-O and Kubelet profiling or scripting, you can configure the type field in the custom resource definition.
The Node Observability Operator is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.
For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.
24.1. Workflow of the Node Observability Operator
The following workflow outlines on how to query the profiling data using the Node Observability Operator:
- Install the Node Observability Operator in the OpenShift Container Platform cluster.
- Create a NodeObservability custom resource to enable the CRI-O profiling on the worker nodes of your choice.
- Run the profiling query to generate the profiling data.
