Point-in-time metric values.

Fields

classified: u64

Successfully classified requests.

rejected: u64

Requests rejected for malformed or ambiguous MCP headers.

unauthenticated: u64

Requests refused for a missing, malformed, or unknown API key. Tracked apart from rejected so credential stuffing is distinguishable from clients that simply send bad protocol headers.

throttled: u64

Requests refused because the authentication-failure budget was spent.

cache_hits: u64

Responses served from cache.

cache_misses: u64

Cacheable requests not served from cache.

billed: u64

Delivered calls accepted by the recorder.

billed_units: u64

Sum of delivered units accepted by the recorder.

free: u64

Exchanges classified as free.

free_by_reason: [u64; 11]

Free exchanges split by reason, indexed by FreeReason::index.

The single free total cannot answer the question the enum exists for: a spike in missing_task_attribution means durable-task charges are being lost, and collapsed into one counter it is indistinguishable from ordinary discovery traffic.

duplicates: u64

Repeated once-only charges suppressed by the recorder.

record_failures: u64

Local recorder failures.

deferred: u64

Terminal accounting parked because it could not finish without awaiting. Only a durable task store produces these.

unrecognized_responses: u64

Bodies that ended without a parseable terminal response.

unrecognized_by_reason: [u64; 4]

Unaccounted responses split by cause, indexed by UnaccountedReason::index.
