Cloud Profiler API C++ Client Library
An idiomatic C++ client library for the Cloud 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. The types of profiling available are listed in the service documentation.
While this library is GA, please note Google Cloud C++ client libraries do not follow Semantic Versioning.
Quickstart
The following shows the code that you'll run in the google/cloud/profiler/quickstart/
directory, which should give you a taste of the Cloud Profiler API C++ client library API.
#include "google/cloud/profiler/v2/profiler_client.h"
#include "google/cloud/project.h"
#include <iostream>
int main(int argc, char* argv[]) try {
if (argc != 2) {
std::cerr << "Usage: " << argv[0] << " project-id\n";
return 1;
}
namespace profiler = ::google::cloud::profiler_v2;
auto client = profiler::ProfilerServiceClient(
profiler::MakeProfilerServiceConnection());
google::devtools::cloudprofiler::v2::CreateProfileRequest req;
req.set_parent(google::cloud::Project(argv[1]).FullName());
req.add_profile_type(google::devtools::cloudprofiler::v2::CPU);
auto& deployment = *req.mutable_deployment();
deployment.set_project_id(argv[1]);
deployment.set_target("quickstart");
auto profile = client.CreateProfile(req);
if (!profile) throw std::move(profile).status();
std::cout << profile->DebugString() << "\n";
return 0;
} catch (google::cloud::Status const& status) {
std::cerr << "google::cloud::Status thrown: " << status << "\n";
return 1;
}
Main classes
This library offers multiple *Client
classes, 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 *Client
classes when testing your application.
