Librato reporting for timers is broken

[bww]

This commit appears to have broken reporting to Librato for timers (at least):
d4f1d62#diff-2a2c532f685bccc6e7eb27c6144a94caR11

From Librato support:

{"attributes":{"display_transform":"x/1000000000","display_units_short":"s"},"count":203896,"max":8.25364642e+08,"min":4.843613e+06,"name":"metric.timer.mean","period":5,"sum_squares":2.79663655195528e+25},

which gives the error (as you mentioned in email to Nik)

{"errors":{"params":{"sum":["is required"]}

I can confirm that this was not a change in API behavior.  If you have a way to actually specify the "sum" field (because it's required if you specify "count"), that should fix the problem.  Docs: http://dev.librato.com/v1/post/metrics "Gauge Specific Parameters"

Also, I'm fairly certain once that's fixed, you'd run into an error with the "4.843613e+06" notation.

Howdy! This was reported a few days ago and I only now finally got around to fixing it today. PR #81 and this additional commit 14abde2 should resolve the issue.

I don't think we've seen an issue with the format before, but let me know if it comes up. Cheers!

Yep, that did it. Thanks!

The number format doesn't seem to be an issue. JSON numbers support E notation so I wouldn't expect it to be a problem.
