Thanks @beekeh -- this should actually also be resolved with #1434 -- although I think it's a little suspect that if you're not using metrics, you need to still specify something about the metrics exporter when using the agent. I'll file an upstream issue.

@chalin do you want to take this in now or await #1434?

I'd wait on #1434.

I think we can actually close this now that #1434 is merged. It's not the exact same thing, but it addresses the issue.
