[RELEASE] Game Logs System (GLS) — The Ultimate Solution for Real-Time Logs in Shipping Builds

[FergiusTerro]

Hello, Unreal Engine community!

We are thrilled to introduce our plugin, Game Log System (GLS), designed to revolutionize how you handle logs during development and in shipping builds. Whether you’re an indie developer or part of a large AAA studio, GLS provides a comprehensive and customizable solution for log collection, filtering, and analysis in real-time, even in final game builds.

Why Choose GLS for Your Project?

Debugging and monitoring logs is a vital part of game development, but it often becomes a time-consuming task, especially when working with large projects or across multiple platforms. GLS simplifies this by offering robust log management tools that work seamlessly in both the editor and gameplay environments, including shipping builds.

If you’ve ever felt limited by the default UE_LOG system or needed more control over your logs across different platforms, GLS is the tool you’ve been waiting for.

Key Features of Game Log System (GLS)

1. Cross-Platform Support:

GLS is fully compatible with Windows, Linux, Consoles, and Android, and we’re actively working on supporting Mac and iOS in future updates. Whether you’re developing for desktop, mobile, or console platforms, GLS has you covered.

2. Log Viewing in Shipping Builds:

One of the standout features of GLS is the ability to collect and view detailed logs even in shipping builds. Using GLS_LOG macros, you can filter logs by classes, objects, and custom tags, offering much more flexibility than the standard UE_LOG system.

This feature is particularly useful when debugging final game builds, where performance issues or bugs might be hard to track without access to in-game logs.

3. Advanced Filtering Capabilities:

Managing large volumes of logs can be challenging, but GLS makes it easy with advanced filtering options:

• Filter by classes, objects, categories, tags, and verbosity levels.
• Save your custom filters for future use, ensuring you can quickly narrow down the logs you need most.

With these tools, you can filter out the noise and focus on what truly matters for your specific debugging tasks.

4. Customizable Overlay Interface:

GLS includes a powerful in-game overlay for viewing logs in real-time. The overlay is highly customizable, allowing you to create separate tabs for different tasks or logging contexts. Each tab retains its state between sessions, so you don’t need to reconfigure everything after every restart.

The overlay supports both gamepad and touchscreen input, making it incredibly versatile for use across multiple platforms, including consoles and mobile devices.

5. Persistent Settings Across Sessions:

No more resetting your filters or display settings after each restart! GLS saves your configurations so that each time you open the overlay or specific log tabs, they will retain their previous states. This helps streamline your workflow, especially when working on long-term projects.

6. High Performance and Scalability:

When working with large projects or extensive logs, performance becomes a key factor. GLS is optimized for high-performance log processing, capable of handling large volumes of logs without slowing down your project. The plugin can process up to 1000 logs per frame (configurable in settings), ensuring smooth performance even under heavy loads.

7. Session and Role-Based Filtering:

GLS allows you to filter logs based on session type (PIE, Standalone) and network roles (Standalone, Client, Listen Server). This is particularly useful when testing multiplayer games, where specific log details may only be relevant to certain roles.

8. Full UE_LOG Integration:

Even if you’re not using GLS_LOG macros, GLS will automatically intercept and process all UE_LOG messages. This ensures that your existing log setup continues to function as expected while benefiting from GLS’s advanced filtering and analysis tools.

9. Export and Share Logs Easily:

Need to share logs with your team or analyze them later? GLS makes it simple to save logs to files or copy them to the clipboard for further analysis. This feature is particularly helpful for larger teams working in distributed environments or when preparing bug reports.

10. PrintString Support:

Easily display game messages directly in GLS through functions like PrintStringToGLS in Blueprints, complete with custom categories. This allows you to streamline messaging and log output into a unified system for both internal use and debugging purposes.

GLS sounds like a game-changer for anyone dealing with complex log management, especially with the ability to view logs in shipping builds and the advanced filtering options. The cross-platform support and customizable overlay are standout features too. Definitely seems like a valuable tool for both indie and large-scale projects. I’m curious, how does the performance hold up with extremely large log volumes in a multiplayer environment? Great work on this!

[FergiusTerro]

Thank you for the kind feedback! We’ve put a lot of effort into optimizing performance, especially for multiplayer projects with large volumes of logs.

1. Optimization using UListView: We made a deliberate choice to display each log as a single element. This ensures that only the logs that fit on the screen are shown at any given time, with the rest loading as you scroll. This prevents overwhelming the interface with too many logs at once, which is crucial when handling large datasets.
2. Log processing and filtering: These processes have been optimized to minimize CPU usage. The system handles complex filtering and log management efficiently, maintaining performance even with a high number of logs.
3. Log retrieval limit per frame: We’ve set a limit of 1000 logs per frame to prevent freezing. This ensures that the overlay remains responsive and clickable, even during periods of high log volume.
4. Memory optimization: We’ve also focused on minimizing memory usage, which is especially important in multiplayer environments with large amounts of data.

So, performance holds up well even with massive log volumes in multiplayer projects. We’ve worked hard to ensure GLS runs smoothly and efficiently in all scenarios. Thanks again for your feedback!

Does the Plugin work with android builds for distribution?, My game is too big to be able to compile a debuggame/development build, Because of the 2GB/4GB limitation,
I need to test a Google release build

[FergiusTerro]

Yes, it’s possible.

The Game Logs System (GLS) plugin is compiled for all configuration modes and activates at runtime based on the settings. To enable the plugin in the shipping configuration, go to Project Settings → Plugins → Game Logs System → Enable Logs In Shipping builds in the editor.

To ensure that GLS captures logs in a distribution build, use GLS_LOG instead of UE_LOG. Unreal completely removes UE_LOG calls in shipping builds, so GLS needs to intercept logs differently.

In a shipping build, you can open the GLS overlay panel by holding two fingers on the screen of the mobile device during gameplay. This will display the logs in a tab on-screen, where you can filter them by specific categories as needed.

Additionally, make sure to set the following in your DefaultGame.ini file:

[/Script/GLS.GLSSettings]
bEnableLogsInShippingBuilds=True

These settings need to be applied when packaging the build.

[FergiusTerro]

To ensure logs are available in the shipping configurations of your game, you can add the following setting in your game’s repository:

DefaultGame.ini
[/Script/GLS.GLSSettings]
bEnableLogsInShippingBuilds=True

However, it’s essential to closely monitor the distribution builds submitted to the store.

When packaging these builds, you must include the -gls_disable build flag. This flag will disable the GLS plugin, preventing the overlay from appearing in the game and ensuring that logs are not collected, even if bEnableLogsInShippingBuilds=True is set to true.

By integrating the -gls_disable build flag into your build pipeline for final builds, you can effectively disable the overlay and log collection, ensuring compliance with the store’s requirements while still enabling logs during development and testing.

Is there any overhead for the logging nodes if GLS is disabled in particular builds?

I ask because the usual print/log has “Development Only” on the node, whereas GLS does not. Are there any performance implications for this?

[FergiusTerro]

GLS is designed with performance in mind. If GLS is disabled for a specific build (e.g., via Project Settings → Plugins → Game Logs System), all GLS subsystems remain inactive, ensuring that no GLS-specific logic or processing runs. This prevents any overhead in builds where GLS is not needed.

Additionally, the GLS_LOG macro is designed to seamlessly redirect logs to the default UE_LOG system if GLS subsystems are inactive. This ensures that log functionality remains intact while avoiding unnecessary processing by GLS.

Here’s how this is achieved:

1. Subsystem Activation Check:
   GLS subsystems are initialized only if GLS is enabled. If GLS is disabled, none of its subsystems (e.g., UGLSSubsystem) are activated, effectively bypassing all GLS-related code.

bool UGLSSubsystem::ShouldCreateSubsystem(UObject* Outer) const
{
    return FGLSUtils::IsGLSEnabled();
}

2. Macro Redirection:
   The GLS_LOG macro checks subsystem status. If GLS is inactive, it directly redirects logs to UE_LOG, ensuring minimal overhead.

#define GLS_LOG(CategoryName, Verbosity, Format, ...) \
if (FGLSUtils::IsGLSEnabled()) \
{ \
        GLSSubsystem->Log(CategoryName, Verbosity, Format, ##__VA_ARGS__); \
} 
else \
{ \
        UE_LOG(CategoryName, Verbosity, Format, ##__VA_ARGS__); \
}

Thanks for the great question!
