Mackerel supports obtaining and monitoring Cloud SQL metrics with Google Cloud Integration. When integrating with Google Cloud Integration, billable targets are determined using the conversion 1 Instance = 1 Micro Host. In addition to this, depending on the number of metrics retrieved, you may be charged for exceeding the maximum number of metrics per micro host.
Please refer to the following page for Google Cloud Integration configuration methods and a list of supported services.
