Hi @wildum 👋 I have no permission to merge the branch. How's the process here, just ping the agent team or will automatically be merged at some time?

Hey sorry for dragging this up, we just made the Alloy repo public and we need to redirect the PRs there. We will only be merging bugfixes to the agent from now on. We are just figuring out a process to make the transition smooth. You don't need to do anything, the PR will be merged to Alloy soon

Hi @wildum any updates on this? We have customers running into this issue.

Hey, super sorry we actually moved all the issues but not the PRs and I forgot about it. Actually this seems to be relevant for the agent as it looks more like a bugfix than an enhancement. I can merge this PR and create a new one in Alloy and get it merged. Is that ok?

[wildum]

here is the alloy PR: https://github.com/grafana/alloy/pull/991. I extended a unit test to check that the float values had the prefix

merged in Alloy, I will also merge it in a bit to the agent

All done, sorry again for the unnecessary delay!

[codecapitano]

Thank you so much and no worries. I think your team had a ton of work around Alloy release time. Ans I could've asked earlier as well.
