Loading A VMware Server

This example uses the ConnectorBean object created in the Connecting tutorial, vcb, to load all the top-most server and all of its properties.

import com.hyper9.uvapi.types.virt.resources.ComputeResourceListBean;
import com.hyper9.uvapi.types.virt.resources.entities.ServerBean;

...

// Load the server from the hypervisor and query its
// cpu, cpu.max, and status properties.
ServerBean vserver = vcb.loadServer(
    Arrays.asList("cpu", "cpu.max", "status"));

// Print the server's current CPU usage.
System.out.println(String.format("%s out of %s", 
                                 vserver.getCpu(),
                                 vserver.getCpuMax());

// Because the ServerBean is a ComputeResourceContainer it 
// knows about the status values of the compute resources
// it contains. Print out the names of any children that
// have a status of red.
if (vserver.getStatusRed() != null)
{
    for (ComputeResource cr : vserver.getStatusRed())
    {
        System.out.println(cr.getName());
    }
}

...

Notice how we were able to retrieve the server's child statuses? This is true for any resource that implements the ComputeResourceContainerBean or ComputeResourceListBean interfaces.

Loading Hosts From A Xen Server

This example uses the ConnectorBean object created in the Connecting tutorial, xcb, to load all available hosts and all of their properties.

import com.hyper9.uvapi.types.virt.resources.ComputeResourceListBean;
import com.hyper9.uvapi.types.virt.resources.entities.HostBean;

...

// Load all of the hosts known to the hypervisor into a
// ComputeResourceListBean<HostBean> list along with
// all of their properties (an asterik specifies that
// the query should retrieve all known properties of
// the queried object type).
ComputeResourceListBean<HostBean> xhosts = 
    xcb.loadAllHosts(Arrays.asList("*"));

// Print out the names of the hosts along with their
// CPU and memory statistics.
for (HostBean hb : xhosts)
{
    System.out.println(hb.getName());
    System.out.println(String.format("cpu: %s out of %s", 
                                     hb.getCpu(),
                                     hb.getCpuMax());
    System.out.println(String.format("mem: %s out of %s", 
                                     hb.getMem(),
                                     hb.getMemMax());
}

Loading VMs From A Hyper-V Server

This example uses the ConnectorBean object created in the Connecting tutorial, hcb, to load all available VMs and all of their properties.

import com.hyper9.uvapi.types.virt.resources.ComputeResourceListBean;
import com.hyper9.uvapi.types.virt.resources.entities.VirtualMachineBean;

...

// Load all of the VMs known to the hypervisor into a
// ComputeResourceListBean<VirtualMachineBean> list and
// load all of their properties.
ComputeResourceListBean<VirtualMachineBean> hvms = 
    hcb.loadAllVMs(Arrays.asList("*"));

// Print out the names of the VMs and the status of the VM.
for (VirtualMachineBean vmb : hvms)
{
    System.out.println(vmb.getName());
    System.out.println(vmb.getStatus());
}
