2988 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

    A platform injects standard labels into every metric it scrapes: team, service, environment, pod and commit SHA. Between deploys the metrics backend is healthy. Within minutes of each fleet deploy, query latency triples, ingester memory climbs and dashboards covering the last six hours time out. Samples per second have not changed. Where is the time going?

    Review this platform telemetry programme. 14 dashboards, a weekly adoption report by capability, per-capability request counters with caller identity, a quarterly developer survey of 38 questions, and DORA metrics computed per product team and published weekly to leadership. Two of the seven platform engineers spend about a day a week each maintaining it. What would you remove, what would you change, and what would you leave alone?
