vm_disk_statistics no io_read / io_write values, all 0

[K van der Wal]

Hello,

When I'm looking in the vm_disk_statistics table inside the cloud 
database and the cloud_usage database, all values are 0. I allready 
enabled the usage server and set the value of vm.disk.stats.interval to 
300 in the global settings. I'm using Cloudstack 4.4.2 with KVM. Does 
anyone know how to get the disk io stats filled ?
