Use the inclusion filter of `(resource.type="gce_subnetwork" AND log_id("compute.googleapis.com/ vpc_flows")) OR (resource.type="vpc_flow_logs_config" AND log_id("networkmanagement.googleapis.com/vpc_flows"))`

{% hint style="info" %}
If you are using org level configuration, you will need to make an agregated logging sink as well at the org level. Use the inclusion filter of `resource.type="vpc_flow_logs_config" AND log_id("networkmanagement.googleapis.com/vpc_flows")`
