The Group API lets you inspect and manage your
`groups <#google.monitoring.v3.Group>`__.
A group is a named filter that is used to identify a collection of
monitored resources. Groups are typically used to mirror the physical
and/or logical topology of the environment. Because group membership is
computed dynamically, monitored resources that are started in the future
are automatically placed in matching groups. By using a group to name
monitored resources in, for example, an alert policy, the target of that
alert policy is updated automatically as monitored resources are added
and removed from the infrastructure.

authorization credentials to attach to requests. These
credentials identify this application to the service. If none

credentials from the environment.
