Struct Counters 

pub struct Counters { /* private fields */ }

The running totals behind the counters in /metrics.

Every gauge the node exported before these described a state it could read on demand – readiness, free disk, ref agreement. Nothing described what had happened, so two of the alerts docs/private-beta-runbook.md calls critical, a spike in refused or failed requests and a breach of the latency gate, had no metric to fire from. These are that, and they are counters rather than gauges on purpose: an alert wants a rate, and a rate needs a number that only ever goes up.

Counted in Access::finish, which every served request passes through, and counted before the request log is consulted – a node started without --request-log still has to be alertable.
