@cwangVT or @iwankgb, what would it take to get this in? Having this built into the tool would save us significant resources vs maintaining this monitoring separately, but we'd prefer not to build our own images just for it. Is there anything that keeps this from being merged?

[aroberts]

If anyone's interested in an external solution, I put together a simple exporter (disclaimer- AI slop) in python over the weekend. Published currently as a docker image (ironically, without a health check).
