Hello @Tomas_65355 ,

Welcome to The MongoDB Community Forums! :wave:

Cloud Manager is a part of Enterprise Advanced and is needed to be setup for every node on the replica set.

A competitive alternate for this can be using MongoDB Atlas as this can also provide monitoring. There are different tiers to choose from, some cheaper than others and one needs to decide according to the requirements if a shared tier will be enough or a dedicated tier is required and how much storage/ram and other resources are required for each node.

Let me know, in case you have any further questions, I will be happy to help you! :slight_smile:

Regards,
Tarun
