Past Performance Data Not Available for a Host through Virtual Center

Hi,

I have a ESXi Host which is reporting 'No Data Available' under its performance Tab through Virtual Center. Realtime performance data is showing up fine, but any past data is not showing up and giving the error as 'No Data Available'.

Within the cluster of 4 Hosts, only one is having the above issue. The others are showing up the performance data fine.

In another ESXi host cluster too connected to the same vCenter, I see one of the host is having similar issue.

I verified:

• All the SQL Rollup jobs are running successfully as per the default schedule.
• Restarted vpxa service by connecting to the host directly using vsphere client.

I was following the KB article http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2007388 . as suggested in the article when I execute the below SQL Query I'm seeing there is no data within that. 

execsp_spaceusedvpx_hist_statx

The output is similar (no data) if I run these queries:

exec sp_spaceused vpx_hist_stat2

exec sp_spaceused vpx_hist_stat3

exec sp_spaceused vpx_hist_stat4

Current setup:

ESXi 5.1.0 799733

vCenter Server 5.1.0 Build 1123961

Please help in resolving this.
