Attribute type conversion for VMs .. ??

[Naineyess]

As I am capturing the entity name of the VMs in the form of string via vCO SNMP traps and I want to map this entity name with the VMs as VC:VirtualMachine which I am not able to do it now.. Please help me out with this..

Thanks,
Naineyess

Hi Naineyess,

we've done this by using a Action which expects the VM-Name and is searching and returning the VM-Object:

Create an action with the following Input / Output:

Input:

- Name: vmName

- Type: string

Output:

- Type: VC:VirtualMachine

Sourcecode:

if ( vmName == "" ) throw "Missing Parameter: Virtualmachine-Name!";

var myVirtualMachines = VcPlugin.getAllVirtualMachines();
for each (var myVirtualMachine in myVirtualMachines)
{
 if ( vmName == myVirtualMachine.name )
  return myVirtualMachine;
}
return null;

Regards,

Marc

Hi Marc,

Thanks your response well I am trying with the same solution which you have provided.. but it is showing some error "Invalid return" ( for return myVirtualMachine;) ..

Thanks !

Did you set the Output of the Action? Or are you using the code directly as Scriptable Task in your Workflow?

Thanks a lot you saved my life ...

The following method will provide much better performance when there are a lot of VMs in your inventory:

var sdkConnections = VcPlugin.allSdkConnections; 
 vms = new Array(); 
 for (var i in sdkConnections) { 
      var host = sdkConnections[i]; 
      var found; 
      if (host.isInventoryServiceAvailable()) { 
           found = host.getAllVirtualMachines(null, "matches(name, '" + criteria + "')"); 
      } else { 
           found = host.getAllVirtualMachines(null, "xpath:matches(name, '" + criteria + "')"); 
      } 
      for (var j in found) { 
           vms.push(found[j]); 
      } 
 }

The above script will search all vCenter connections. For each one, it will attempt to find a vm that has the matching name. It then adds the matching vms to an array called vms... Ideally, you would hope for only 1 match . The technique shown here has the flexibility for you to add your own error checks after the matching vm(s) has been found.
