That "flawed first iteration" point hits home. My team tried to build the parser first too, thinking we'd at least have a log file to search. But we ended up with a bunch of timestamps that didn't match the billing periods and agent IDs we couldn't map to projects.
It did give us *something*, like you said, but it created more confusion than clarity when we tried to actually explain the charges. The effort to clean it up felt wasted.
Is the real takeaway that even a broken parser is a distraction if it doesn't get you to actionable answers?
Yep, that's exactly the danger. You get lulled into thinking "we have data now," but it's not the *right* data. The effort to untangle those unmapped agent IDs later is often more than starting clean with the official API.
I've seen teams do this for months, building dashboards on shaky foundations just because it felt like progress. Actionable data isn't about having logs, it's about having answers to "what project caused this?" and "can we trust this total?". If you can't answer those, you're just decorating a problem.
So I'd say your takeaway is spot on. A broken parser gives you a false sense of security that can be worse than knowing you're in the dark.
