From MongoDB Atlas Performance Advisor to Obsfly

• Atlas-only. Self-hosted Mongo or non-Atlas clusters get nothing.
• Performance Advisor is reactive — surfaces problems after they happen, not before.
• No multi-engine view; teams running Postgres + Mongo end up with two tools.
• No forecast-based capacity alerts.

Fairness signal — useful in renewal conversations.

• Free with Atlas — useful as a baseline.
• Tight integration with Atlas-native operations.

1. Step 1

   Connect Obsfly to your Atlas clusters

   Read-only monitoring user via Atlas DB Access. No agent install needed.

2. Step 2

   Map non-Atlas Mongo too

   Self-hosted, EKS, GCP MongoDB Enterprise — all covered the same way.

3. Step 3

   Set up forecast-band rules

   Predict working-set growth, oplog window shrinkage, and disk fill 30+ days out.

4. Step 4

   Keep Performance Advisor

   It's free; run both. Use Obsfly for cross-fleet, alerting, and forecast.

• Atlas's Performance Advisor uses its own slow-query threshold; align it with Obsfly's profiler config.

Can Obsfly drive Atlas auto-scaling?

Indirectly — Obsfly forecasts let you raise the Atlas tier proactively rather than waiting for the auto-scale trigger.
