Verified on FB – https://github.com/Percona-Lab/pmm-submodules/pull/2748#issuecomment-1235326240
Server Docker – perconalab/pmm-server-fb:PR-2748-8b2c396
Now mongodb_version_info has edition label with "Community" or "Enterprise" value:
Community:
Enterprise:
In the scope of this ticket we want that mongodb_exporter show whether Mongo DB Enterprise or Community edition.
For this we can extend mongodb_exprorter by adding additional label `edition` to the `mongodb_version_info` metric which shows this info.
