Ruby Client for the Cloud Monitoring API Cloud Monitoring collects metrics, events, and metadata from Google Cloud, Amazon Web Services (AWS), hosted uptime probes, and application instrumentation. Actual client classes for the various versions of this API are defined in versioned client gems, with names of the form google-cloud-monitoring-v*. The gem google-cloud-monitoring is the main client library that brings the verisoned gems in as dependencies, and provides high-level methods for constructing clients.
