MongoDB Replica Sets Repeating in Global View (4380653)

MongoDB replica sets are showing up multiple times in the Global View (GV). This happens across different agents monitoring separate clusters. 

All MongoDB clusters are using the same replica set name (e.g., rs0). Foglight uses this name to identify and group replica sets. When multiple clusters share the same name, Foglight merges their data, causing duplication in the Global View.

To fix this, configure Replica Set Aliases in each MongoDB agent’s properties. This tells Foglight to treat each replica set as unique, even if they share the same internal name.

Steps to Configure Replica Set Aliases

1. Open the MongoDB agent properties from the Agent Status dashboard.
2. Locate the MongoDB agent (e.g., mongo-agent-dev, mongo-agent-prod, mongo-agent-test).
3. Click the gear icon or right-click > Edit Properties.
4. Scroll to the MongoDB Agent Options section and open the Replica Set Aliases popup.
5. Enter a unique alias for each replica set monitored by that agent only.

Example Mappings

Each agent should only include the replica set(s) it monitors. Do not include aliases for replica sets monitored by other agents.

For mongo-agent-dev:

For mongo-agent-prod:

For mongo-agent-test:

Final Steps

• Click OK or Apply to save the changes.
• Restart the agent to apply the new configuration.
• Verify in Global View that each replica set appears only once under its correct cluster.
