It's funny this is coming up now. Just yesterday in GCP I was trying to figure out our billing and looking at what was costing such a huge amount. I couldn't figure out any way to map the actual service being used to the price on the normal reporting or even on the billing cost table export. The only way I could figure out how to do it was to enable log export. They used to have an option to download that as a file. They disabled that a while ago and now it's only available as a bigquery export. Which is exported every day. I was like "Why would that they do that ?" Oh cause now I have to set up big query and pay for all that. So I have to pay extra JUST TO SEE my detailed billing information. Pretty ridiculous.
