# Live system metrics

> The public operations dashboard for Pulse: real-time presence counts, a live visitor world map, event throughput, and latency, read straight from the running .NET + Redis + Postgres backend.

## What is on this page

A public ops dashboard for the system running this site. Presence comes from a TTL-pruned Redis sorted set behind a SignalR hub; visit events travel through a RabbitMQ transactional outbox to a worker that writes the audit log and aggregates in Postgres; traces and metrics are exported over OpenTelemetry. The numbers here are live, not sampled fixtures.
