代码示例

C#

public static object DeleteMetric(string projectId, string metricType)
{
    // Create client.
    MetricServiceClient metricServiceClient = MetricServiceClient.Create();
    // Initialize request argument(s).
    MetricDescriptorName name = new MetricDescriptorName(projectId, metricType);
    // Make the request.
    metricServiceClient.DeleteMetricDescriptor(name);
    Console.WriteLine($"Done deleting metric descriptor: {name}");
    return 0;
}
