@weltenwort is this only available in stateful? I'm not seeing the setting in serverless, but I could be looking in the wrong place.

[weltenwort]

hm, good question. I don't think we're intentionally hiding it from serverless. let me investigate...

[weltenwort]

Ok, TIL there is an allow-list for advanced settings in serverless. The setting to turn on the logs overview is not in there, so it is effectively not available in serverless.

@gbamparop do we want to make the tech preview feature flag for the logs overview available or is it intentionally not exposed?

I may just merge this PR then, and update if/when it goes into serverless.

sounds reasonable 👍 thanks for catching this

@weltenwort I don't think that this was intentional. Let's discuss with @LucaWintergerst next week about whether we will keep the advanced setting in Stateful with the work that we're planning next for the logs overview component. If we do then we can add it to Serverless too.
