Working with Cloudera on premises diagnostic data

Cloudera on premises enables you to generate and download diagnostic data associated with the various services and workloads for troubleshooting purposes. You can perform these tasks from the Diagnostic Data tab of the Management Console.

Cloudera on premises uses fluentd to collect logs from the Cloudera Management Console services, and the Cloudera AI, Cloudera Data Warehouse, and Cloudera Data Engineering workloads. If Ozone is configured to store logs from the workloads, the information collected by fluentd is stored on Ozone. Otherwise, the data is moved through a fluentd aggregator in the Cloudera Management Console to an OpenShift Container Platform persistent volume where all the Cloudera Management Console logs are also stored.

When an administrator selects the option to generate the diagnostic bundle from the Cloudera Management Console > Administration > Diagnostic Data page, Cloudera Management Console generates a bundle containing the following details after querying the relevant components and services:
  • Logs from the OpenShift Container Platform persistent volume
  • Cloudera AI, Cloudera Data Warehouse, and Cloudera Data Engineering logs stored on Ozone
  • Kubernetes deployment information such as events, logs, details of the OpenShift Container Platform pods and so on.
  • Metrics for monitoring such as usage information and so on.
  • Cloudera Management Console information such as version, UUID, and so on.
