Chapter 10. Generating a diagnostic bundle

You can generate a diagnostic bundle and send that data to enable the support team to provide insights into the status and health of Red Hat Advanced Cluster Security for Kubernetes components.

Red Hat might request you to send the diagnostic bundle during investigation of your issues with Red Hat Advanced Cluster Security for Kubernetes. You can generate a diagnostic bundle and inspect its data before sending.

Note

The diagnostic bundle is unencrypted, and depending upon the number of clusters in your environment, the bundle size is between 100 KB and 1 MB. Always use an encrypted channel to transfer this data back to Red Hat.

10.1. Diagnostic bundle data

When you generate a diagnostic bundle, it includes the following data:

  • Central heap profile.
  • System logs: Logs of all Red Hat Advanced Cluster Security for Kubernetes components (for the last 20 minutes) and logs of recently crashed components (from up to 20 minutes before the crash). System logs depend on the size of your environment. For large deployments, data includes log files for components with critical errors only, such as a high restart count.
  • YAML definitions for Red Hat Advanced Cluster Security for Kubernetes components: This data does not include Kubernetes secrets.
  • OpenShift Container Platform or Kubernetes events: Details about the events that relate to the objects in the stackrox namespace.

  • Online Telemetry data, which includes:

    • Storage information: Details about the database size and the amount of free space available in attached volumes.
    • Red Hat Advanced Cluster Security for Kubernetes components health information: Details about Red Hat Advanced Cluster Security for Kubernetes components versions, their memory usage, and any reported errors.
    • Coarse-grained usage statistics: Details about API endpoint invocation counts and reported error statuses. It does not include the actual data sent in API requests.
    • Nodes information: Details about the nodes in each secured cluster. It includes kernel and operating system versions, resource pressure, and taints.
    • Environment information: Details about each secured cluster, including Kubernetes or OpenShift Container Platform version, Istio version (if applicable), cloud provider type and other similar information.
