Set Up Logs

With Sentry Structured Logs, you can send text-based log information from your Godot Engine applications to Sentry. Once in Sentry, these logs can be viewed alongside relevant errors, searched by text-string, or searched using their individual attributes.

Requirements

Logs for Godot Engine are supported in Sentry Godot SDK version 1.1.0 and above.

Setup

To enable logging in your Godot project, you need to configure the Sentry SDK with Logs enabled.

Project Settings Configuration

1. Open Project Settings in Godot, and navigate to Sentry > Experimental.
2. Turn on the Enable Logs option.

Programmatic Configuration

Alternatively, you can enable logs programmatically when initializing the SDK:

SentrySDK.init(func(options: SentryOptions) -> void:
	options.experimental.enable_logs = true
)

Usage

Once the feature is enabled on the SDK and the SDK is initialized, you can send logs using the SentrySDK.logger APIs.

The SentrySDK.logger exposes six methods that you can use to log messages at different log levels: trace, debug, info, warn, error, and fatal.

SentrySDK.logger.trace("Initialized inventory database")
SentrySDK.logger.debug("Player inventory updated")
SentrySDK.logger.info("Level loaded successfully")
SentrySDK.logger.warn("Item configuration not found")
SentrySDK.logger.error("Failed to save game state")
SentrySDK.logger.fatal("Inventory data corrupted")

Godot Logging Integration

When the feature is enabled, the SDK automatically captures Godot messages, warnings, and errors as logs. You can use print(), push_warning(), and push_error() as usual. These show up as info, warning, and error logs. The SDK also turns runtime errors and warnings into events based on your configuration.

Options

before_send_log

To filter logs, or update them before they are sent to Sentry, you can use the before_send_log option.

SentrySDK.init(func(options: SentryOptions) -> void:
	options.experimental.enable_logs = true
	options.experimental.before_send_log = _before_send_log
)

func _before_send_log(log_entry: SentryLog) -> SentryLog:
	# Filter junk.
	if log_entry.body == "Junk message":
		return null
	# Remove sensitive information from log messages.
	log_entry.body = log_entry.body.replace("Bruno", "REDACTED")
	# Add custom attributes.
	log_entry.set_attribute("current_scene", current_scene.name)
	return log_entry

The before_send_log function receives a SentryLog object, and should return either the same log object, with or without modifications, or null if you want to discard it.

Default Attributes

The Godot SDK automatically sets several default attributes on all log entries to provide context and improve debugging:

Core Attributes

• environment: The environment set in the SDK if defined. This is sent from the SDK as sentry.environment.
• release: The release set in the SDK if defined. This is sent from the SDK as sentry.release.
• sdk.name: The name of the SDK that sent the log. This is sent from the SDK as sentry.sdk.name.
• sdk.version: The version of the SDK that sent the log. This is sent from the SDK as sentry.sdk.version.

User Attributes

• user.id: The user ID. Maps to id in the User payload, which is set by default by the SDKs.

If user information is available in the current scope, the following attributes are added to the log:

• user.name: The username. Maps to username in the User payload.
• user.email: The email address. Maps to email in the User payload.

Integration Attributes

If a log is generated by an SDK integration, the SDK will set additional attributes to help you identify the source of the log.

• origin: The origin of the log. This is sent from the SDK as sentry.origin.

Troubleshooting

Performance Considerations

• Logs are sent asynchronously to avoid impacting game performance.
• Consider disabling debug level logs in production to avoid excessive log volume.
• before_send_log callback is executed synchronously, so keep processing lightweight.
