An idiomatic C++ client library forCloud Logging API, a service that writes log entries and manages your Cloud Logging configuration.
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/logging/quickstart/directory, which should give you a taste of the Cloud Logging API C++ client library API.
#include "google/cloud/logging/v2/logging_service_v2_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 logging = ::google::cloud::logging_v2;
auto client = logging::LoggingServiceV2Client(
logging::MakeLoggingServiceV2Connection());
auto const project = google::cloud::Project(argv[1]);
for (auto l : client.ListLogs(project.FullName())) {
if (!l) throw std::move(l).status();
std::cout << *l << "\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*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.
