Description

When I access the Host Details page for :

http://172.22.76.13:8080/api/v1/clusters/leapsec/hosts/leapsec-rhel6-11.openstacklocal?fields=metrics/cpu/cpu_user[1436028521,1436032121,15],metrics/cpu/cpu_wio[1436028521,1436032121,15],metrics/cpu/cpu_nice[1436028521,1436032121,15],metrics/cpu/cpu_aidle[1436028521,1436032121,15],metrics/cpu/cpu_system[1436028521,1436032121,15],metrics/cpu/cpu_idle[1436028521,1436032121,15]&_=1435698892786

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:

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

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).
