How to Use Cloud Debugger For Debugging Applications On GCP?

Application debugging is a crucial step in the development process since it enables developers to quickly find and fix problems. Developers can debug their applications running on the Google Cloud Platform (GCP) with the help of a potent tool called Cloud Debugger without interfering with their regular operation. In this article, we'll examine Cloud Debugger's capabilities and offer a detailed tutorial on how to utilize it.

What is Cloud Debugger?

It is a cloud-based debugging solution offered by GCP that enables developers to examine and analyze the state of their running apps. Without considerable logging or the requirement to replicate the issue, it assists in finding and resolving problems in production systems. Java, Python, Node.js, and Go are just a few of the programming languages that Cloud Debugger supports.

Why do we use Cloud Debugger?

For developers, the Google Cloud Platform (GCP)'s Cloud Debugger has a number of advantages and use cases. The following are some justifications for using Cloud Debugger on GCP:

1. Debugging in production: When your applications are operating in a production environment, Cloud Debugger enables you to debug them in real time. With this, you may investigate the state of the application without interfering with how it normally functions. This is very helpful when problems or errors appear in live deployments.
2. Reduced logging and code reproduction: Cloud Debugger offers a more effective technique to identify difficulties than depending just on logging statements or attempting to reproduce complicated situations. You can quickly and efficiently identify the root of a problem within a running application by establishing breakpoints and analyzing variables.
3. Remote debugging: You can remotely debug programs with Cloud Debugger without needing physical access to the production environment. When debugging distributed systems or working with applications that are operating in virtual or containerized environments, this is extremely helpful.
4. Collaborative debugging: During the debugging process, Cloud Debugger makes it easier for developers to work together. Because multiple team members may access the debugging session at once, observe breakpoints, and discuss the code and problems in real-time, issues can be resolved more quickly and knowledge can be shared.

Setting up Cloud Debugger

Follow these steps to start utilizing Cloud Debugger:

Step 1: Set up a GCP project.

In the Google Cloud Console, create a project or pick one that already exists(https://console.cloud.google.com).

Step 2: Enable the Cloud Debugger API

Go to the API Library in the Cloud Console, type in "Cloud Debugger API," and turn it on for your project.
Step 3: Install the Cloud Debugger agent

Install the suitable Cloud Debugger agent library or package based on the programming language used for your application.

Debugging Your Application

You can begin debugging once your application has been instrumented with Cloud Debugger and breakpoints have been established. Take these actions:

Step 1: Deploy your application

Make sure your instrumented application is up and functioning before deploying it to GCP.

Step 2: Start a debugging session

Select your project and application from the dropdown menus on the Debugger page of the Cloud Console. To start a debugging session, click the "Start debugging" button.

Step 3: Inspect variables and stack traces

The Cloud Debugger will halt the execution of your application when a breakpoint is reached. The stack trace can then be explored, variables' current states examined, and other pertinent data can be examined to comprehend how the application behaves.

Step 4: Modify code and resume execution

Debugging may reveal problems that call for modifying the code. Direct edits can be made in the source view of the Cloud Console, and execution can be resumed to see the results of your changes.

Advanced Features and Considerations

To improve your debugging experience, Cloud Debugger provides the following extra features and suggestions:

• Breakpoints with conditions: You can limit debugging to pertinent scenarios by setting breakpoints that only activate under certain circumstances.
• Remote code snapshots: During debugging sessions, Cloud Debugger takes code snapshots, giving you a look back at the behavior of your application.
• Access controls and permissions: Make sure that the right access controls and permissions are set for debugging, as this could expose critical data and code.

Conclusion

For the purpose of debugging apps running on GCP, Google Cloud Platform offers the sophisticated Cloud Debugger tool. You may quickly find and fix problems without interfering with your application's usual functioning by turning on Cloud Debugger, instrumenting your app, and setting breakpoints. The debugging process is streamlined by Cloud Debugger's user-friendly UI and cutting-edge technologies, which enable developers to create GCP apps that are more stable and reliable.
