How to find age of a snapshot and child snapshot count for a VM.

Hi All,

    How to find age of a snapshot and Child Snapshot count for a VM.

This snippet of code should help.. Assuming you have the following inputs:

vm (VC:VirtualMachine)

snapshot (VC:VirtualMachineSnapshot)

System.log("====== Snapshot details for VM: "+snapshot.config.name+" ======");
var snapshotTrees = vm.snapshot.rootSnapshotList;
System.log("Snapshot Tree Count: "+snapshotTrees.length);
for each (snapshotTree in snapshotTrees){
    showSnapshotInfo(snapshotTree, snapshot);
}

function showSnapshotInfo(snapshotTree, selectedSnapshot){
    if(selectedSnapshot == snapshotTree.snapshot){
        System.log("====================");
        System.log("Name: "+snapshotTree.name);
        System.log("Id: "+snapshotTree.id);
        System.log("Description: "+snapshotTree.description);
        System.log("createTime: "+snapshotTree.createTime);
        System.log("quiesced: "+snapshotTree.quiesced);
        System.log("replaySupported: "+snapshotTree.replaySupported);
        System.log("backupManifest: "+snapshotTree.backupManifest);
        System.log("snapshot id: "+snapshotTree.snapshot.id); 
        System.log("state: "+snapshotTree.state.value);
        var childSnapshotList = snapshotTree.childSnapshotList;
        if(childSnapshotList != null){
            System.log("childSnapshotList length: "+snapshotTree.childSnapshotList.length);
        }
        System.log("");
    }
    if(snapshotTree.childSnapshotList != null){
        System.log("Children found: "+snapshotTree.childSnapshotList.length);
        for each (childSnapshotTree in snapshotTree.childSnapshotList){
            showSnapshotInfo(childSnapshotTree, selectedSnapshot);
        }
    }
}

When I pass one of my VMs, here is an example of the output I receive:
