How to find management IP(s) of ESXi host from VcHostSystem (vRO 7.3 and vSphere 6.0)

[aenagy]

This (How to find management IP(s) of ESXi host from VcHostSystem (vRO 7.3 and vSphere 6.0) ) is being re-posted here.

I am trying to find the ESXi host to which a virtual machine is registered. From the vm I am able to find the host (VcHostSystem) in vRO. Searching the API it would appear that I need HostVirtualNicManagerNicType (http://pubs.vmware.com/vsphere-6-0/topic/com.vmware.wssdk.apiref.doc/vim.host.VirtualNicManager.NicT...). The code below allows me to iterate over the virtual NICs and includes IP address information but I haven't figured out how to definitively determine which interface(s), and therefore which IP(s), are designated for ESXi management.

var          EsxiHostConfigNetworkdVnic = vm.runtime.host.config.network.vnic  
System.log( "EsxiHostConfigNetworkdVnic.length = " + EsxiHostConfigNetworkdVnic.length )  
for( var VnicIndex = 0 , VnicLength = EsxiHostConfigNetworkdVnic.length ; VnicIndex < VnicLength ; VnicIndex++ ){  
System.log( "EsxiHostConfigNetworkdVnic[" + VnicIndex + "] = " + EsxiHostConfigNetworkdVnic[ VnicIndex ] )  
}  

Thanks in advance.

Something like the following should work:

var vnicManager = vm.runtime.host.configManager.virtualNicManager;
var netConfig = vnicManager.queryNetConfig(VcHostVirtualNicManagerNicType.management);
System.log("Selected vNics: " + netConfig.selectedVnic);
System.log("Candidate vNics: ");
for each (var vNic in netConfig.candidateVnic) {
  if (netConfig.selectedVnic.indexOf(vNic.key) == -1) {
    System.log("vNic[ " + vNic.key + " ] is not selected; skipping it");
    continue;
  }
  System.log("vNic[ " + vNic.key + " ] is selected");
  System.log(vNic.spec.ip);
}

That worked perfectly. My final action code looks like this:

// INPUT:
//   vcHostSystem (VcHostSystem)
var actionResult = ""
var vnicManager = vcHostSystem.configManager.virtualNicManager
var netConfig = vnicManager.queryNetConfig(VcHostVirtualNicManagerNicType.management);  
//System.log("Selected vNics: " + netConfig.selectedVnic);  
//System.log("Candidate vNics: ");  
for each ( var vNic in netConfig.candidateVnic ) {
    if (netConfig.selectedVnic.indexOf( vNic.key ) == -1) {  
        //System.log("vNic[ " + vNic.key + " ] is not selected; skipping it");  
    } else {
        //System.log("vNic[ " + vNic.key + " ] is selected");  
        //System.log(vNic.spec.ip);  
        actionResult += vNic.key.split( "." )[3].split( "-" )[1] + " IP: " + vNic.spec.ip.ipAddress + "  "
    }
}  
return actionResult

Thanks.
