Metrics

Collect metrics and export Prometheus-compatible metrics with the built-in registry.

Exporting Metrics

• Use metrics.Registry to register counters, gauges and histograms.
• Expose metrics endpoint and call registry.scrape() to generate Prometheus text.

Example:

var registry = try metrics.Registry.init(allocator);
registry.registerCounter("requests_total", "Total requests");
app.get("/metrics", (ctx) => Response.text(registry.scrape()))

See src/metrics.zig for implementation details and health check integrations.
