Maximizing Productivity: The Keys to Streamlined Engineering Troubleshooting

Here is a complete guide for streamlining engineering troubleshooting.

Troubleshooting is time-consuming and tiring. From API timeouts to network issues and misconfigurations, engineers must fix everything. Something solvable in ten minutes can easily take several hours. After substantial brainstorming, our experts bring this comprehensive guide to rationalizing troubleshooting efforts.

Common Pitfalls to Avoid While Troubleshooting.

  • De-emphasizing the issue: Reducing the problem’s scope increases its complexity. Being forthright and honest with cases’ severity is better. 
  • Playing alone: Bring developers, testers, and users together. It leads to practical solutions.  
  • Blind trust in search results: While consulting qualified websites is ok, blindly following them can force intricate useless changes. 
  • Making irreversible changes: Make a change only when a rollback is possible. Irrevocable change can introduce errors that take additional troubleshooting hours. 
  • Improper logs: Engineers must follow record keeping. When confusion increases, the documentation helps reduce complexity.  
  • Applying shotgun methods: For a quick fix, sys admins implement multiple solutions simultaneously, increasing trouble. 
  • Downplaying ramifications: Look at the big picture to accurately anticipate the consequences of every step.
  • Introspection: Revisit the problem once it is solved. It helps trigger additional safeguards to prevent its repetition. 

Prepare for Troubleshooting.

Troubleshooting is a systematic approach to problem-solving. Some of the following preparatory steps can ensure precise resolution.

Applications preparation:

  • Signal exchange validity between components.
  • Structured log for defining attributes.
  • APIs to temporarily disable features and fix issues.
  • Database log analyzer and monitoring system.
  • Test reports with maximum coverage and performance benchmarks.

Cluster preparation:

  • Cluster audits to determine API calls, their timing, and source.
  • Documentation of services the apps provide.
  • Documentation of system configurations.
  • A runbook documenting operation flow, known errors, and their resolution procedure.

Team preparation:

  • Understand possible errors using observability tools.
  • Study the context to register errors’ fault points and impact.
  • Familiarize the team with supporting system tools.

6 Key Steps to Troubleshooting 

Based on extensive experience in troubleshooting, we identify a systematic approach to problem-solving as below. 

  1. Examine and diagnose. 

We begin with system monitoring and logging to identify errors, their type, and relevant configuration.

  1. Simplify and eliminate non-issues. 

Analyze the flow between applications. Minimize tests by narrowing down the error location using bisection and divide and conquer techniques.

  1. Identify the cause.

Ideally, components have well-defined functions and interfaces. Use flags, tracing, or other methods to identify factors causing deviation from their typical behaviour.

  1. Determine the system’s last operational state.

Systems follow the law of inertia and do not change their outputs until an external change is initiated. It can be a sudden traffic shift or a configuration change. Recent activities on the system help cognize what went wrong.

  1. Attempt a fix.

Implement solutions one at a time, beginning with the most plausible one. Implementation results serve as a guide for the next and save significant time.

  1. Assess and document.

Evaluate the results, their longevity, and repeatability. Also, jot down issues it caused (if any) for future reference.

Troubleshooting best practices 

IT troubleshooting can be simplified by implementing standard guidelines across the enterprise. Here are seven best practices that can reduce your troubleshooting efforts remarkably.

  • Address issues before they grow into significant failures
  • Backup before beginning to enable rollbacks
  • Collect information to replicate the errors and find an adequate fix.
  • Create error outputs at the source code level to better understand and localize the problem.
  • Differentiate between symptoms and the root causes of the problem
  • Log with correlations to identify related components and the impact of the issue/solution on them.
  • Use analytics to draw actionable insights to prevent reoccurrence. 

Conclusion

IT Troubleshooting is a part of continuous improvement. Establishing a well-defined strategy to resolve issues is inevitable. With a decade-long experience delivering 150+ products across multiple environments, we resonate with the pain that goes into troubleshooting.
