masque_metrics (masque v0.7.0)

View Source

Metrics instrumentation for masque tunnels.

Uses instrument_meter to track tunnel lifecycle, throughput, and rejections. Call setup/0 from application start. Instruments are stored in persistent_term for zero-overhead lookups.

Summary

Functions

bytes_in(Bytes, Attrs)
bytes_out(Bytes, Attrs)
ip_advertise_inc()
ip_advertised_count()
ip_assign_inc()
ip_assigned_count()
ip_drop_count(Reason)
ip_drop_inc(Reason)
ip_drop_reasons()
ip_release_inc()
ip_released_count()
setup()
setup_ip_counters()

Idempotent allocator for the IP-side simple counters. Safe to call multiple times; only the first call wins (subsequent calls keep the existing reference so counts accumulated from earlier callers are preserved).

tunnel_closed(DurationMs, Attrs)
tunnel_opened(Attrs)
tunnel_rejected(Attrs)
