Under each method, its extensions (Q CS XT Z ZZ IB W U): bold and ticked, it exists; struck, it does not. The extensions and what they mean
No method of this class is run on this page: the class reaches files, the network, processes, the clock, chance or sound, and an example run here would only be an example of its effects. Each method carries the explanation the library gives of itself.

Explanation, as the source carries it
init

Name_
(no comment in the source: the name reads as a sentence) name_no extension
NewTraceId
trace ids ---------------------------------------------------------- A fresh, monotonic, URL-safe id: "t-<clockbase>-<seq>". Unique within this recorder; the clock base keeps two recorders from colliding.no extension
RecordRequest
recording ---------------------------------------------------------- Record one COMPLETED request: its trace id, the facet, the endpoint that served it (or "none"), the final HTTP status, the end-to-end latency in ms, and how many workers were attempted (>1 = failover).no extension
LatencyPercentile
latency percentiles (per facet) ------------------------------------ Upper-bound (ms) of the bucket holding percentile nP for a facet's request latency. 0 when the facet has no samples yet.no extension
LatencyP50
Same as LatencyPercentile: latency percentiles (per facet) ------------------------------------ Upper-bound (ms) of the bucket holding percentile nP for a facet's request latency. 0 when the facet has no samples yet.no extension
LatencyP90
Same as LatencyPercentile: latency percentiles (per facet) ------------------------------------ Upper-bound (ms) of the bucket holding percentile nP for a facet's request latency. 0 when the facet has no samples yet.no extension
LatencyP95
Same as LatencyPercentile: latency percentiles (per facet) ------------------------------------ Upper-bound (ms) of the bucket holding percentile nP for a facet's request latency. 0 when the facet has no samples yet.no extension
LatencyP99
Same as LatencyPercentile: latency percentiles (per facet) ------------------------------------ Upper-bound (ms) of the bucket holding percentile nP for a facet's request latency. 0 when the facet has no samples yet.no extension
LatencyCount
(no comment in the source: the name reads as a sentence) latency countno extension
LatencyStats
A one-shot snapshot the health console reads.no extension
Facets
The facets that have received at least one sample.no extension
NumberOfTraces
trace lookupsno extension
RecentTraces
The last n request records (most recent last), as [ id, facet, endpoint, status, durMs, attempts ] rows.no extension
LastTrace
(no comment in the source: the name reads as a sentence) last traceno extension
TraceById
The record for a given trace id (the most recent if reused), or [].no extension
FailoverTraces
The trace ids whose request failed OVER (attempts > 1) -- the visible footprint of the circuit breaker / retry path.no extension
Narrate
(no comment in the source: the name reads as a sentence) narrateno extension
Destroy
teardown (engine histograms hold native handles)no extension
