What it does

The task

Sign in to the billing pages of these cloud accounts: accounts. Read the cost per service for this month to date and for the same days last month. List the services where the cost grew by more than threshold. For each one, open the usage details and find the projects, regions or resources that grew the most. Save a table with the service, both costs, the change and the cause as a new tab in the Google Sheet sheet url. Do not change or delete any resource.

  • It works in any admin panel and Google Sheets, in the workspace you pick, and signs in with passwords from your Cuiar vault.
  • It runs once, when you start it.
