Description of problem:
-----------------------
Any drop down selection on the Utilization page of VM/host/cluster is not being honored.

After capturing C&U data for a provider, I tried to view the following C&U graphs for a VM:
1)Hourly graphs
2)Graphs for 'Most recent hour'
3)C&U graphs in comparison with host/cluster

The default option for the C&U graphs is 'Daily'.The daily graphs are displayed properly.But,they don't change after a drop down selection is made.So,I'm unable to view the graphs for the hourly,most recent hour intervals and unable to compare the VM graphs with parent host/cluster graphs.

Version-Release number of selected component (if applicable):
--------------------------
5.5.5.0


How reproducible:
----------------
Always


Steps to Reproduce:
-------------------
1.Enable C&U collection for a provider.
2.From the summary page of a VM, click Monitoring, click Utilization.
3.On the Utilization page, make various drop down selections.


Actual results:
---------------
Drop down Selections on Utilization pages not being honored


Expected results:
-----------------
Drop down Selections on Utilization pages should be honored.
