@nguoingoai MongoDB exporter supports versions of MongoDB server, which have not hit EOL. You can check EOL dates for MongoDB server. The server version tested by you has hit EOL, hence it is not supported.

We would recommend moving to a newer version. Let us know if you believe there is a valid use case to support older versions.

Upgrade mongo to newer version will take me very long time , I see some other tool such as netdata still support well with EOL mongodb version , so if mongo_exporter can support this case I thinks it is very great.

Can you try out the latest version of MongoDB exporter? It may work with older version of MongoDB server. You can selectively enable collectors there, so it might work for your use case.

Yeap I am using the lasted version of mongo_exporter
