MongoDB integration

MongoDB is a document-based, distributed database built for modern applications. The MongoDB integration gives you visibility into operational health, replication, and resource usage.


What it monitors	Operations, connections, replication status, memory usage, document metrics
How it works	Grafana Alloy’s built-in MongoDB exporter scrapes metrics from your MongoDB instance
What you get	10 alerts + 3 dashboards (Cluster, Instance, ReplicaSet)
Prerequisites	MongoDB user with monitoring privileges

What you’ll see in the dashboards

MongoDB Cluster — Cluster-wide node counts (up/down), operation counters, and resource usage
MongoDB Instance — Per-instance connection statistics, operation counters (insert, query, update, delete), and performance metrics
MongoDB ReplicaSet — Replication lag, member states, and oplog window

Trade-offs

Strengths	Considerations
Purpose-built dashboards for MongoDB operations	Infrastructure metrics only — no query-level analysis
Replica set monitoring and alerting	Requires a dedicated monitoring user
Minimal configuration with Alloy’s built-in exporter	Does not cover sharded cluster-specific metrics

The MongoDB integration monitors operational health, replication, and resource usage for MongoDB instances. It uses Grafana Alloy’s built-in MongoDB exporter to scrape metrics and ships with 10 alerts and 3 dashboards.

The dashboards cover three levels. The Cluster dashboard shows cluster-wide node counts, operation counters, and resource usage. The Instance dashboard drills into per-instance connection statistics and performance metrics. And the ReplicaSet dashboard tracks replication lag and member states.

MongoDB isn’t supported by Database Observability, so the integration is the primary monitoring approach. It provides infrastructure-level metrics but not query-level analysis.
