Dashboard overview

The dashboard is organised around five top-level areas.

Methods

Per-method timing, error rate, p50/p95/p99 latency, top callers. Drill into any method to see traces, MongoDB calls, outbound HTTP, and logs from a specific invocation.

Reactive (publications & observers)

The view nobody else has. For each publication:

• Driver mix — what fraction of subscriptions are using change_stream, oplog, or polling.
• Observer count — total live observers, with leak detection (a monotonically-rising count over a steady connection count).
• DDP message rate — how many messages this pub is pushing per minute.

MongoDB

Query timing, index usage, slowest queries, and a COLLSCAN watcher.

Infrastructure

Hosts, processes, event-loop lag, RSS memory, restart counts.

Uptime & status pages

External monitors and your hosted status pages. See the Monitors guide for setup.
