What should you do?

In the Google Cloud Platform Console, use the Cost Breakdown section to visualize the costs per system.
Assign all instances a label specific to the system they run. Configure BigQuery billing export and query costs per label.
Enrich all instances with metadata specific to the system they run. Configure Stackdriver Logging to export to BigQuery, and query costs based on the metadata.
Name each virtual machine (VM) after the system it runs. Set up a usage report export to a Cloud Storage bucket. Configure the bucket as a source in BigQuery to query costs based on VM name.
