prometheus module generates invalid output when counter names contain non-alphanum characters
When I enabled an MDS, I found that prometheus threw an error scraping our stats. I assume it's due to counter names (maybe the ones that have a plus/minus sign in them?)

I created an account just so I could submit this bug… so I concur,
mds_mem_cap+ is an example (the first sequentially) of one on which prometheus choked.
