echo "Instance status: $instanceStatus"
if [ $instanceStatus == passed ]; then 
    echo "Instance check status passed..."
fi

# Get system status...
systemStatus=$(aws ec2 describe-instance-status --region us-east-1 --instance-ids $instanceID --query 'InstanceStatuses[0].SystemStatus.Details[0].Status' --output text)
