Someguy metrics

Someguy exposes a Prometheus endpoint at http://127.0.0.1:8190/debug/metrics/prometheus by default.

The endpoint includes the default Prometheus Go client metrics plus the Someguy-specific metrics listed below.

Delegated HTTP Routing (/routing/v1) server

boxo/routing/http/server (the /routing/v1 handler) exports metrics with the delegated_routing_server_ prefix:

  • delegated_routing_server_http_request_duration_seconds_[bucket|sum|count]{code,handler,method}: histogram of HTTP request latency
  • delegated_routing_server_http_response_size_bytes_[bucket|sum|count]{code,handler,method}: histogram of HTTP response size

Delegated HTTP Routing (/routing/v1) client

When Someguy aggregates other /routing/v1 endpoints, boxo/routing/http/client exports metrics with the someguy_ prefix:

  • someguy_routing_http_client_latency_[bucket|sum|count]{code,error,host,operation}: histogram of operation latency
  • someguy_routing_http_client_length_[bucket|sum|count]{host,operation}: histogram of response collection size

Someguy caches

  • someguy_cached_addr_book_probe_duration_seconds_[bucket|sum|count]: histogram of peer-probing duration in seconds
  • someguy_cached_addr_book_probed_peers{result}: counter of probed peers, labeled online or offline
  • someguy_cached_addr_book_peer_state_size: gauge of peers currently tracked in peer state
  • someguy_cached_router_peer_addr_lookups{cache,origin}: counter of peer address-info lookups per origin and cache state
