Crate moduvex_observe 

moduvex-observe

Observability for the Moduvex framework: structured logging, distributed tracing, metrics collection, and health checks — all built on moduvex-runtime with zero external async runtime dependencies.

Quick Start

use moduvex_observe::prelude::*;

// Install the default subscriber (reads MODUVEX_LOG / MODUVEX_LOG_FORMAT).
moduvex_observe::init_logging();

// Structured logging
info!("request handled", status = 200, path = "/users");

// Metrics
let counter = Counter::new("http_requests_total", "Total HTTP requests");
counter.inc();

Modules

export

Metric and log exporters.

health

Health check system: trait-based checks with aggregated status.

log

Structured logging: Level, Event, and Value types.

metrics

Lock-free metrics: Counter, Gauge, Histogram, and a global Registry.

prelude

trace

Distributed tracing: TraceId, SpanId, Span lifecycle, and task-local context.

Macros

debug

Emit a DEBUG-level log event.

error

Emit an ERROR-level log event.

info

Emit an INFO-level log event.

log_event

Emit a log event at an explicit level.

trace

Emit a TRACE-level log event.

trace_event

Emit a TRACE-level log event (alias kept for backward compatibility).

warn

Emit a WARN-level log event.

Functions

init_logging

Install the default structured-log subscriber.
