Troubleshooting is a critical skill for site reliability engineers (SREs). Using past experiences, a proper mindset, and a stable troubleshooting process, SREs can effectively report, triage, examine, diagnose, test, and cure system issues. In this course, you'll explore troubleshooting approaches and best practices, while also learning how to avoid common pitfalls. You'll explore issue reporting, triaging, examination, diagnosis, and testing. You'll recognize how to simplify and reduce troubleshooting, use the ""what, why, and where"" technique, and examine negative results. You'll also investigate how to observe and interpret recent changes to identify what went wrong with a system. Lastly, you'll locate probable cause factors and outline the steps used to make troubleshooting more effective.

WHAT YOU WILL LEARN

  • Discover the key concepts covered in this course
    Describe how engineers think differently to "novices" when it comes to troubleshooting
    Outline best practices and approaches to troubleshooting and how to keep those skills sharp
    Outline an idealized troubleshooting model (e.g., report, triage, examine, diagnose, test/treat, and cure.)
    List potential pitfalls to avoid, such as looking for symptoms that are not relevant
    Outline how to manage operational loads
    Recognize the importance of an adequate initial problem report
    Recognize the importance of triaging problems from the onset
    Recognize the importance of examining each component of a system to understand whether it is functioning properly
  • Identify the steps and approaches used to diagnose issues
    Describe methods for testing and treating possible causes to identify actual problems
    Recognize how to simplify and reduce troubleshooting using techniques such as dividing and conquering
    Describe the "what, why, where" technique and how it can be used to diagnose a malfunctioning system
    Interpret how determining who last touched a system can be helpful when identifying what is going on with a system
    Define what is meant by "negative results"
    Recognize that systems are complex and that often you can only identify probable cause factors to document what went wrong with a system
    Outline steps to make troubleshooting easier
