When I access the Host Details page for :

However, look at the screenshot. The start time (1435946268) and using the
standard +3600 seconds for the end time (1435949868), the following call was
made:
{code}
http://172.22.76.13:8080/api/v1/clusters/leapsec/hosts/leapsec-rhel6-11.openstacklocal?fields=metrics/cpu/cpu_user[1435946268,1435949868,15],metrics/cpu/cpu_wio[1435946268,1435949868,15],metrics/cpu/cpu_nice[1435946268,1435949868,15],metrics/cpu/cpu_aidle[1435946268,1435949868,15],metrics/cpu/cpu_system[1435946268,1435949868,15],metrics/cpu/cpu_idle[1435946268,1435949868,15]&_=1435698626557
{code}
This resulted in 13.6MB of data transferred in 12.05s. The result set size is
exactly consistent with what is in the screenshot.
Note that this result set contained a bunch of data that are *outside* of the
time window specified [1435946268,1435949868).
