The Stackdriver Monitoring API v3 gives you access to over 900 Monitoring metrics from Google Cloud Platform and Amazon Web Services. You can create your own custom metrics and can organize your cloud resources using groups.
For the API reference documentation, see Stackdriver Monitoring API.
For an introduction to metric concepts and the data structures that represent them, see Metrics, Time Series, and Resources.
To learn how to manage your custom metrics and the built-in metrics, see Using Custom Metrics.
For a complete list of available metrics, see Metrics List.
A monitored resource is something about which metrics are collected. For example, you might be interested in the activity of a VM instance or a piece of hardware.
For a list of the available monitored resources, see the Monitored Resource List.
Monitored resource groups
A group is a dynamic collection of monitored resources. You have always been able to create groups manually in Monitoring, but the v3 API allows you to write code that creates and uses groups.
For more information, see the Group collection in the API.
An alerting policy is a configuration resource that describes the
criteria for generating incidents and how to notify you when those incidents
are created. Alerting concepts explains the basic concepts
of alerting policies. For more information, see the
The API also lets you create alerting policies based on a ratio of two metrics.
Ratios cannot currently be created through the Monitoring console.

A notification channel is a configuration resource that describes how to notify you when incidents occur. Notification channels can reference a variety of different kinds of communication services and endpoints; these are specified in descriptors. The descriptors determine the set of configuration parameters that are included in a channel object.
The v3 API uses filters to select metrics, to fetch time-series data, and to collect monitored resources into groups. For more information, see Monitoring Filters.
The v3 API also uses filters to restrict the result set of certain
operations. See Sorting and Filtering for details
on managing the results of the
