Support Engineers

This path assumes you already have some day-to-day exposure to ticket queues and basic troubleshooting, and focuses on turning ad-hoc, memory-dependent investigation into a repeatable method. It moves from a specific debugging habit (reading logs backward) through a structured isolation technique, into root-cause thinking, and ends with building your own incident-ready checklist and the mindset shift that turns support experience into systems thinking over time.

If you only have time for a subset of this path, the four-stop core is: reading logs backward, isolating network vs. application, root-cause analysis, and building your own checklist — the rest adds depth and career context around that core.

1. 1 Reading Logs Backwards: A Debugging Habit  Guide · beginner
   Why reading logs from the moment of failure backward, instead of scrolling forward from an arbitrary starting point, is faster and catches the real cause more reliably.
2. 2 Isolating "Is It the Network or the App?"  Troubleshooting Walkthrough · intermediate
   A step-by-step method for isolating whether a slow or failing request is a network problem, a proxy/load-balancer problem, or an application problem — before you start reading application logs.
3. 3 HTTP Status Codes You'll Actually See in Production  Guide · beginner
   The HTTP status codes that actually show up in day-to-day support and operations work, what each one really means, and which ones point at the client vs. the server.
4. 4 IIS Application Pools: What They Are and Why They Crash  Guide · beginner
   What an IIS application pool actually is, why it stops or crashes, and how to tell the difference between an app pool problem and an application code problem.
5. 5 Monitoring 101: Metrics, Logs, and Traces  Guide · beginner
   The three pillars of observability explained plainly — what metrics, logs, and traces each tell you, and which one to reach for first depending on the question you're actually asking.
6. 6 Root Cause Analysis: A Simple Framework  Guide · intermediate
   A practical, repeatable framework for finding a real root cause instead of stopping at the first plausible explanation — the Five Whys, contributing-vs-root-cause, and writing a blame-free postmortem.
7. 7 Build Your Own Troubleshooting Checklist  Playbook · beginner
   A playbook for building your own personal, incident-ready troubleshooting checklist — a concrete template plus the reasoning for why a checklist beats relying on memory under pressure.
8. 8 From Support Work to Systems Thinking  Career Advice · intermediate
   How to move from reactively closing tickets to proactively understanding and improving the systems behind them — a concrete shift in mindset, not just a title change.
9. 9 Asking for Technical Help Effectively  Career Advice · beginner
   How to ask a senior colleague for help in a way that gets you a fast, useful answer instead of a frustrated one — what to include, what to try first, and why 'it doesn't work' is the least useful sentence in tech.
