An idiomatic C++ client library for theCloud Profiler API, a service that manages continuous CPU and heap profiling to improve performance and reduce costs.
Note that this library allows you to interact with Cloud Profiler, but Cloud Profiler does not yet offer profiling of C++ applications. Thetypes of profiling availableare listed in the service documentation.
While this library isGA, please note Google Cloud C++ client libraries donotfollowSemantic Versioning.
Quickstart
The following shows the code that you'll run in thegoogle/cloud/profiler/quickstart/directory, which should give you a taste of the Cloud Profiler API C++ client library API.
This library offers multiple*Clientclasses, which are listed below. Each one of these classes exposes all the RPCs for a service as member functions of the class. This library groups multiple services because they are part of the same product or are often used together. A typical example may be the administrative and data plane operations for a single product.
The library also has other classes that provide helpers, configuration parameters, and infrastructure to mock the*Clientclasses when testing your application.
