Description of your problem
We are installing Graylog from the ground up, but not sure which mongodb version to use.
Should we follow directions on: Red Hat Installation: Single Graylog Node and version 4.2 for CentOS
or https://docs.mongodb.com/upcoming/tutorial/install-mongodb-on-red-hat/ with version 5.X
that is not mentioned as supported?
Operating system information
Rocky Linux release 8.4 (Green Obsidian)
