How to retrieve a list of idle GCP Disks in CloudHealth?
Suggest to download the GCP Disks asset report and filter by the ‘Unattached Date’ along with ‘In Use’ column. https://apps.cloudhealthtech.com/assets/gcp/compute/disks
‘In Use = No’ means the disk is unattached, than look how long ago it was Unattached.
According to GCP docs, If a resource has not been attached to a VM or other resource for 15 days, the Recommender classifies that resource as idle. https://cloud.google.com/compute/docs/viewing-and-applying-idle-resources-recommendations
