Recommender C++ Client Library

This directory contains an idiomatic C++ client library for Recommender, a service on Google Cloud that provides usage recommendations and insights for Cloud products and services.

While this library is GA, please note that the Google Cloud C++ client libraries do not follow Semantic Versioning.

Quickstart

The quickstart/ directory contains a minimal environment to get started using this client library in a larger project. The following "Hello World" program is used in this quickstart, and should give you a taste of this library.

For detailed instructions on how to build and install this library, see the top-level README.

#include "google/cloud/recommender/v1/recommender_client.h"
#include "google/cloud/location.h"
#include <iostream>

int main(int argc, char* argv[]) try {
  if (argc != 3) {
    std::cerr << "Usage: " << argv[0] << " project-id location-id\n";
    return 1;
  }

  auto const location = google::cloud::Location(argv[1], argv[2]);

  namespace recommender = ::google::cloud::recommender_v1;
  auto client =
      recommender::RecommenderClient(recommender::MakeRecommenderConnection());
  // For additional recommenders see:
  //     https://cloud.google.com/recommender/docs/recommenders#recommenders
  auto const parent =
      location.FullName() +
      "/recommenders/google.compute.instance.MachineTypeRecommender";
  for (auto r : client.ListRecommendations(parent)) {
    if (!r) throw std::move(r).status();
    std::cout << r->DebugString() << "\n";
  }

  return 0;
} catch (google::cloud::Status const& status) {
  std::cerr << "google::cloud::Status thrown: " << status << "\n";
  return 1;
}
