How to do proper error handling in a push setup?

I am currently building a lab environment to get a feeling on what DSC can accomplish and where the limits are.

We have a requirement to push out one-shot configurations to group of nodes based on criterias like operating system, AD group membership and OUs containing the targets.

So I developed the following exemplary script:

# Pulls computer objects from Active Directory
Function Get-Nodes
{
    Param($OperatingSystem)

    Get-AdComputer -Filter 'OperatingSystem -eq ${OperatingSystem}' -SearchBase "OU=SomeThing,DC=contoso,DC=com"
}

# Defines the configuration to apply
Configuration ConfigureHostsPush 
{
    Node $Allnodes.NodeName
    {
        # This resource is not able to delete a key, only values 
        Registry ConfigureRegistry
        {
            Ensure = "Present"
            Key = "HKEY_LOCAL_MACHINE\SOFTWARE\"
            ValueName = "MachineType"
            ValueData = "Hyper-V"
        }

        # This logs the defined message at the _destination_ host
        # within Microsoft->Windows->DesiredStateConfiguration->Analytic
        # requires showing and enabling the log first!
        Log LogSuccessfulRegistry
        {
            Message = "Successfully configued the defined registry value"
            DependsOn = "[Registry]ConfigureRegistry"
        }
    }
}

$nodes = Get-Nodes -OperatingSystem "Windows Server 2012 R2 Standard"
# $nodes = Get-Nodes -OperatingSystem "Windows Server 2008 R2 Standard"
# $nodes = Get-Nodes -OperatingSystem "Windows 7 Professional"

# Pulls a list of nodes into a hash table
$ConfigData = @{
    AllNodes = @(
        foreach ($node in $nodes)
        {
            @{NodeName = $node.Name}
        }
    )
}

# Generate the MOFs based on the configuration and hosts pulled from AD
ConfigureHostsPush -ConfigurationData $ConfigData

# Actually push out the configuration to the nodes
Start-DscConfiguration -wait -Path D:\DATA\DSC\ConfigureHostsPush

However some of the nodes are not always reachable and are offline in my case. How should I do the error handling and logging? So I can later on control which nodes got successfully configured or needs reconfiguration.

I know I can use the DSC log resource, but that seems to be pretty limited and only generates logs on the LCM/target node side.
