corium::profiler Namespace Reference

Classes
class	Counter
	Atomic 64-bit monotonically increasing counter. More...
struct	FlightRecord
	Represents a single traced event record in the circular flight recorder. More...
class	FlightRecorder
	Zero-heap circular flight recorder storing the last N event telemetry records. Thread-safe for multiple producers and concurrent reader/dumping. More...
class	FlightRecorderProfiler
	Combined Flight Recorder and Latency Tracker Profiler. Records historical event traces into a circular in-memory buffer with zero heap allocations. More...
class	Gauge
	Atomic 64-bit signed gauge metric representing instantaneous level. More...
class	Histogram
	Statically bucketed latency distribution histogram. More...
class	LatencyTracker
	Real-time event latency and performance statistics tracker. Zero dynamic memory allocation. Tracks min, max, total queue latency and handler duration. More...
struct	NullProfiler
	Default Profiler Policy: Zero-overhead, completely compiled out by inline empty functions. More...
class	PostTimestampQueue

Typedefs
using	ProfilerClock = std::chrono::steady_clock
	Timestamp clock used by the profiler (steady clock in nanoseconds).

Functions
size_t	formatPrometheusCounter (const Counter &c, std::span< char > buf) noexcept
	Format counter in Prometheus exposition text format into a char buffer.
size_t	formatPrometheusGauge (const Gauge &g, std::span< char > buf) noexcept
	Format gauge in Prometheus exposition text format into a char buffer.
