Yeah, I believe that's correct. It would be cool if we persisted this to 
a table, but it may be better to just use another metrics 
gathering/storage system here rather than reimplement the wheel since we 
have nothing here presently.

Eric did write an Accumulo backend for OpenTSDB. I don't think that 
would give enough insight to all the types of stuff we track, but I 
could be mistaken :)
