This article discusses the resource and performance metrics that can be obtained from Google Compute Engine (GCE), an infrastructure-as-a-service platform within the Google Cloud Platform. The majority of available metrics are related to low-level resources, such as CPU utilization and network throughput. These metrics can generally be broken down into three categories: instance metrics, disk metrics, and network metrics. Additionally, project metrics provide information on resource consumption/growth over time and anticipate potential future issues. The article also mentions that memory metrics are not available without using a third-party tool.
