Consider putting this in a ToString() method, like you did for the Config struct
(would use field names then, rather than plain text, btw).

I agree, but in this case not all the reported metrics are stored as fields as
they are handled before being reported. 

I'll land this CL as it is, but I'd be happy to to change this later.
