Error Reporting client libraries

This page shows how to get started with the Cloud Client Libraries for the Error Reporting API. Client libraries make it easier to access Google Cloud APIs from a supported language. Although you can use Google Cloud APIs directly by making raw requests to the server, client libraries provide simplifications that significantly reduce the amount of code you need to write.

Read more about the Cloud Client Libraries and the older Google API Client Libraries in Client libraries explained.

Install the client library

C#

Install-Package Google.Cloud.ErrorReporting.V1Beta1 -pre

For more information, see Setting Up a C# Development Environment.

Go

go get cloud.google.com/go/errorreporting

For more information, see Setting Up a Go Development Environment.

Java

If you are using Maven, add the following to your pom.xml file. For more information about BOMs, see The Google Cloud Platform Libraries BOM.

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>libraries-bom</artifactId>
      <version>26.49.0</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

<dependencies>
  <dependency>
    <groupId>com.google.cloud</groupId>
    <artifactId>google-cloud-errorreporting</artifactId>
  </dependency>
</dependencies>

If you are using Gradle, add the following to your dependencies:

implementation 'com.google.cloud:google-cloud-errorreporting:0.173.0-beta'

If you are using sbt, add the following to your dependencies:

libraryDependencies += "com.google.cloud" % "google-cloud-errorreporting" % "0.173.0-beta"

If you're using Visual Studio Code, IntelliJ, or Eclipse, you can add client libraries to your project using the following IDE plugins:

• Cloud Code for VS Code
• Cloud Code for IntelliJ
• Cloud Tools for Eclipse

The plugins provide additional functionality, such as key management for service accounts. Refer to each plugin's documentation for details.

For more information, see Setting Up a Java Development Environment.

Node.js

npm install --save @google-cloud/error-reporting

For more information, see Setting Up a Node.js Development Environment.

PHP

composer require google/cloud-error-reporting

For more information, see Using PHP on Google Cloud.

Python

pip install --upgrade google-cloud-error-reporting

For more information, see Setting Up a Python Development Environment.

Ruby

gem install google-cloud-error_reporting

For more information, see Setting Up a Ruby Development Environment.

Set up authentication

To authenticate calls to Google Cloud APIs, client libraries support Application Default Credentials (ADC); the libraries look for credentials in a set of defined locations and use those credentials to authenticate requests to the API. With ADC, you can make credentials available to your application in a variety of environments, such as local development or production, without needing to modify your application code.

For production environments, the way you set up ADC depends on the service and context. For more information, see Set up Application Default Credentials.

For a local development environment, you can set up ADC with the credentials that are associated with your Google Account:

1. Install the Google Cloud CLI, then initialize it by running the following command:

   gcloud init

2. If you're using a local shell, then create local authentication credentials for your user account:

   gcloud auth application-default login

   You don't need to do this if you're using Cloud Shell.

   A sign-in screen appears. After you sign in, your credentials are stored in the local credential file used by ADC.

Use the client library

The following example shows how to use the client library.

C#

using Google.Api.Gax.ResourceNames;
using Google.Cloud.ErrorReporting.V1Beta1;
using System;

public class ErrorReportingSample
{
    static String projectId;

    public static void Main(string[] args)
    {
	    // Set your Google Cloud Platform project ID via environment or explicitly
        if (args != null && args.Length > 0 && !String.IsNullOrEmpty(args[0]))
        {
            projectId = args[0];
        }
        else
        {
            projectId = Environment.GetEnvironmentVariable("GOOGLE_CLOUD_PROJECT");
        }

        try
        {
            throw new Exception("Something went wrong");
        }
        catch (Exception e)
        {
            ReportError(e);
            Console.WriteLine("Stackdriver Error Report Sent");
        }
    }


    /// <summary>
    /// Report an exception to the Error Reporting service.
    /// </summary>
    private static void ReportError(Exception e)
    {
        // Create the report and execute the request.
        var reporter = ReportErrorsServiceClient.Create();
        var projectName = new ProjectName(projectId);

        // Optionally add a service context to the report. For more details see:
        // https://cloud.google.com/error-reporting/reference/rest/v1beta1/ServiceContext

        var serviceContext = new ServiceContext()
        {
            Service = assemblyName.Name,
            Version = assemblyName.Version.ToString(),
        };
        var errorEvent = new ReportedErrorEvent()
        {
            Message = e.ToString(),

			log.Printf("Could not report the error: %v", err)
		},
	})
	if err != nil {

	}
	defer errorClient.Close()

	err = errors.New("something went wrong")
	if err != nil {
		logAndPrintError(err)
		return
	}
}

func logAndPrintError(err error) {
	/// Client autopopulates the error context of the error. For more details about the context see:
	/// https://cloud.google.com/error-reporting/reference/rest/v1beta1/ErrorContext
	errorClient.Report(errorreporting.Entry{
