@rhtyd - There have been four things fixed here. I have explained each
commit below. Your review/comments is most appreciated.
1. Goto Zone metrics or Hosts metrics. NUmerical values are not listed
under Mem Usage and Mem Allocation columns. Instead 'NaN' is displayed
- Mainly happening due to missing checks for undefined.
2. Create a Windows instance on a Xen cluster. No IOPS data is generated or
shown in the Disk Usage Tab for that Instance: In some cases the diskiops from
API comes back as 0. In this case, calculated it based on disk read and write
values.
3. Changing storage.overprovisioning factor should cause changed values in
storage metrics. This doesnt happen currently: The disk overprovisioning
factor was not considered when calculating metrics 'disk total' and 'disk
allocated'. Added this in.
4. Allocated memory is not correctly calculated on Hosts Metrics page for a
xen server with multiple instances: The value being returned from API was %
value. The Host metric page shows this in GB. Converted it correctly.
