PrometheusLayer

api_tools::server::axum::layers::prometheus

Struct PrometheusLayer 

Source 
pub struct PrometheusLayer {
    pub service_name: String,
}
Expand description

Prometheus metrics layer for Axum.

Records http_requests_total (counter) and http_requests_duration_seconds (histogram) for every request, labeled by method, path (the matched route — bounded cardinality), service and status. Requests to /metrics are excluded.

System metrics (CPU, memory, swap, disks) are not collected here. Use spawn_system_metrics_collector at startup instead.

Fields§

§service_name: String

Service name used as a label on every metric.
