It would be great if the collector exposed a health check that could be used for determining if the process is healthy or not.

We run this collector in ECS. For some reason, it got stuck and wasn't sending any diagnostics upstream. We had to manually restart it to make it work again. If the collector exposed a health check endpoint, we could include it in the ECS task definition which would prevent this from happening.

I imagine that a health check endpoint would be useful for other deployment methods as well.
