Very relatable experience with log diving, feels very much like a needle-in-haystack problem that gets so much harder when you're not the only one who contributed to the source of errors (often the case).

As for the skepticism with LLMs stumbling around raw logs: it's super deserved. Even the developers who wrote the program often refer to larger app context when debugging, so it's not as easy as throwing a bunch of logs into an LLM. Plus, context window limits & the relative lack of "understanding" with increasingly larger contexts is troublesome.

We found it helped a lot to profile application logs over time. Think aggregation, but for individual flows rather than similar logs. By grouping and ordering flows together, it's bringing the context of thousands of (repetitive) logs down to the core flows. Much easier to find when things are out of the ordinary.

Still a lot of improvements in regards to false positives and variations in application flows.
