Comment 2 for bug 1246264

to play devil's advocate, i would question whether the fix should be done in Ceilometer as it is just a collector/listener. from an audit view, if we store the data different from how we receive it, it breaks the integrity of the record since it's been tampered with (although knowingly).

also, the overhead of going through every key of every record and normalising it makes me believe it there's a better way... (is there a better way in Ceilometer?)
