Document that Graylog 4.3.x supports MongoDB 5

This README says:

Hint: Graylog 4.3.x does support MongoDB 5.0, which allows for a seamless upgrade path.

However, these pages mention MongoDB 4.4 being the maximum supported version.

Can you please:

  • Confirm that Graylog 4.3.x supports MongoDB 5?
  • Update the Graylog 4.3.x documentation to reflect that?

Hello @lmm5247

Graylog 5 beta can support MongoDb 5.0 right now. I don’t think it release in the wild yet.

You can find more here about what version on MongoDb to use with Graylog 4.3.x.

EDIT: I think I get now, since its still in beta, I do believe this maybe the cause why Graylog documentation is not updated.

What about the README that says Graylog 4.3.x supports MongoDB 5.0? I’d like to upgrade to MongoDB 5.0 on my current Graylog instance if possible.


If your referring to GitHub then I would suggest looking at instead.

As of today 11/10/2022

Graylog Beta 3

EDIT: TBH I’m waiting till the full release of Graylog 5.0 comes out, then I will do the upgrade from 4.3 to 5.0. Even thou it states 4.3 is able to support that version its basically for a smooth upgrade process but I would imaging if you insist on wanting Mongo 5.0 its possible but user beware also if this is a production environment I wouldn’t take the chance. Normally when its posted in the main Graylog documentations I know its good to go then.

Joining the discussion here because its specifically this case why I signed up :slight_smile:
I think the problem here is that the documentation states that Graylog 4.3.X supports MongoDB up until 4.4, but for running Graylog 5 the documentation states:

Running Graylog 5.0 requires MongoDB 5.0 or 6.0.

So I am a bit puzzled how to actually do upgrades from Graylog 4.3.X to Graylog 5 as v4 only supports MongoDB up until 4.4 but for v5 I need MongoDB 5.X or 6.X - seems like a chicken-and-egg problem.

Looking forward for the clarification :slight_smile:

Going off this README:

Graylog 5 needs at least MongoDB 5.0. Our recommended upgrade path is to first bring your MongoDB to 5.0 and then perform the Graylog upgrade. Hint: Graylog 4.3.x does support MongoDB 5.0, which allows for a seamless upgrade path.

For what it’s worth, I’m running MongoDB 5 with Graylog 4.3 currently.
