Observability Platform · View 07 of 25 · Structure
Decisions
- Admission is its own layer, above collection and below reduction, because putting it anywhere else changes what the platform can promise: enforce in the SDK and you cannot update it, enforce in the store and it fails as an outage.
- Control & governance is a layer rather than a sidebar. It holds the only state in the platform that cannot be rebuilt, and every layer above it reads from it.
Reading it
- Three edges are drawn and the rest are omitted on purpose: gateway to buffer, buffer to store, and store to alert evaluation. Those three carry the availability argument; the others would only restate the layer order.
Risks
- Seven layers of transformation between an emitting process and a queryable result is seven places a record can be dropped. View 21 exists because that chain is only trustworthy if each link is measured.
