MongoDB integration

The MongoDB integration provides database monitoring for MongoDB deployments, from simple standalone instances to complex sharded clusters. Connection tracking matters here because MongoDB’s default connection limits are low.


What it’s for	Monitoring operations, connections, replication, and sharding health
Under the hood	Makes MongoDB’s internal complexity accessible through clear dashboards

Metrics collected

The integration collects metrics across operations, connections, replication, and sharding:

Operations: Queries, inserts, updates, deletes
Connections: Current, available, usage
Replication: Oplog window, member state
Sharding: Chunk distribution, balancer

What to know

This integration offers:

Prebuilt dashboards: overview, replication, sharding
Prebuilt alerts: replication lag, connections
Replica set and sharding visibility
Oplog window monitoring for disaster recovery

Path completed

MongoDB ranges from standalone instances to sharded clusters, and the integration handles all of them. Operation metrics break down by type to show workload patterns, and connection tracking matters because MongoDB’s default limits are low.

For replica sets, watch the oplog window and member states, which are critical for disaster recovery. For sharded clusters, you get chunk distribution and balancer activity.

MongoDB’s internal complexity is real, but the dashboards make it accessible without deep MongoDB expertise.
