Cloud Monitoring API C++ Client Library

An idiomatic C++ client library for the Cloud Monitoring API , a service to manage your Cloud Monitoring data and configurations. This library is used to interact with the Cloud Monitoring API directly. If you are looking to instrument your application for Cloud Monitoring, we recommend using OpenTelemetry or a similar framework.

While this library is GA, please note Google Cloud C++ client libraries do notfollow Semantic Versioning .

Quickstart

The following shows the code that you'll run in the google/cloud/monitoring/quickstart/ directory, which should give you a taste of the Cloud Monitoring API C++ client library API.

 #include "google/cloud/monitoring/v3/alert_policy_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 monitoring = ::google::cloud::monitoring_v3;
  auto client = monitoring::AlertPolicyServiceClient(
      monitoring::MakeAlertPolicyServiceConnection());

  auto const project = google::cloud::Project(argv[1]);
  for (auto a : client.ListAlertPolicies(project.FullName())) {
    if (!a) throw std::move(a).status();
    std::cout << a->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 gRPC service as member functions of the class. This library groups multiple gRPC 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.
