Hey folks! I'm pretty new to the whole DevOps and SRE scene and I've hit a bit of a wall when it comes to debugging through logs. Honestly, I often feel like I'm just aimlessly searching or filtering without a clear understanding of what's actually happening. When multiple services are involved, it gets even trickier for me to piece everything together. I'm reaching out to those of you with more experience—how did you manage to get better at working with logs? Are there any specific practices, tools, or perspectives that really helped you feel more confident and less overwhelmed? Any genuine advice would mean a lot to me! Right now, logs just feel like a barrier rather than a useful resource.

Have you looked into tracing? It does involve some initial setup, but the payoff is big—you can see logs for individual requests hopping between services, all in one trace. It can really make debugging easier!
An effective approach is to start small. Get used to the normal logs of one service before trying to connect logs from multiple services. This will give you a clearer understanding and help you avoid feeling overwhelmed.
One key tip is to familiarize yourself with the documentation for your observability tools. This knowledge will help you understand how to filter logs effectively and create insightful visuals from metrics. Additionally, having a solid mental model of your application infrastructure is crucial—know which services communicate and the big picture of your compute stack. If you're lacking in either area, definitely dig into the docs and don't hesitate to ask more experienced colleagues for help. Collect as many clues as possible, then start validating your assumptions.
