no statistics data displaying for some hosts in vcenter

Hi

Issue : No statistics data displaying for some hosts in vcenter ( In summary tab its cpu and memory showing 0MHz & 0MB)

Disconnect and reconnect host fixed the issue as per below kb.

VMware KB: Migrating an ESXi/ESX host from one vCenter Server to another without disconnecting may cause statistics …

But our vcenter version is 5.5 (build:1746248) the kb above mentioned is for vCenter Server 4.0.x, 4.1.x, 5.0, and 5.1.

Esxi version :Esxi 5.1 Update 3 (2323231)

Is this fixed in 5.5?
