Exercise 1 - Diagnosing and Troubleshooting OpenStack Services

Ansible is a tool-set developed based on OpenStack software tools. Ansible is targeted at being scalable and user-friendly while deploying production environments. The Ansible script is organized into units called playbooks. Each playbook supports a specific server configuration or s specific role.

OpenStack services use the standard logging levels, below is the brief introduction about when to use each log level while troubleshooting the operational issues in an OpenStack deployment.

  • Debug: Shows all the logs that were collected in the infrastructure. Due to the amount of information that is collected, it is not a recommended log level in a production environment.
  • Info: Provides information about actions that were performed successfully in the environment, for example, the successful starting or stopping of services.
  • Warning: Indicates that there might be system issues. The administrator should implement preventive measures.
  • Error: An error has occurred in the infrastructure, and an administrator must research the event to rectify the error to ensure the functionality of the OpenStack environment.
  • Critical: An error has occurred in the OpenStack infrastructure, which may cause the system to become unstable. Immediate resolution of this critical error is crucial.

In this exercise, you will learn to diagnose and troubleshoot various OpenStack services.
