Google Compute Engine (GCE) is a fully managed infrastructure-as-a-service platform that enables users to spin up virtual machines on demand. It powers high-profile businesses such as Philips, Evernote, and HTC. GCE provides a range of metrics related to low-level resources, including CPU utilization, network throughput, memory utilization, and disk read/write bytes. These metrics can be categorized into three main areas: instance metrics, which shed light on resource utilization at the individual host level; network metrics, which monitor traffic and packet drops; and project metrics, which track resource consumption and growth over time. Understanding these metrics is crucial for diagnosing performance issues in hosted applications and identifying friction points in the infrastructure.
