Missing Disk I/O running vCenter Operations 5.0.1 on ESX/ESXi 4.0.x and earlier (2020649)
This issue occurs because datastore I/O metrics are only exposed from a host that is ESX/ESXi 4.1 or later.
This is a limitation of metrics provided by an ESX/ESXi 4.0 or earlier host.
To workaround this issue, you must upgrade to a version later than ESX/ESXi 4.1. To download a version of ESX/ESXi, go to the VMware download site.
For more information on upgrading, see Upgrading ESX/ESXi 3.5 or 4.0 to ESX 4.1 (1022140).
