NaN Problems with Folsom #6

Hello,

I'm trying to run Canary on OpenStack Folsom (using the stable/folsom branch of Canary). I have everything set up and can see data via the "nova canary-query" tool.

But when I try to view graphs on Horizon, I'm getting a bunch of NaN errors. Looking at the access logs shows requests for:

GET /canary/nova-ab/metrics/load.load/?resolution=2&from_time=NaN&cf=AVERAGE

Any idea what I have done wrong?

Thanks, Joe

Hi Joe, sorry for the massive delay.

This probably isn't relevant anymore, but perhaps you could include the output from the different nova canary-* commands? It seems likely that there's some weird timestamp math in Horizon, and we'd love to fix this and any clues would be awesome.
