// Enable or disable the collection of analytics events such as user interactions.
// This includes button taps, screen transitions, and other significant user actions.
// Setting this to false will prevent New Relic from capturing such events automatically.
analyticsEventEnabled: true,
// Enable or disable reporting of network errors (e.g., 4xx, 5xx HTTP status codes)
// as MobileRequestError events. This includes HTTP request failures, timeouts,
// and server errors.
// Useful for identifying failed API requests and backend issues.
networkErrorRequestEnabled: true,
// Enable or disable tracking of all successful HTTP requests as MobileRequest events.
// This captures request URL, status code, response time, and other metadata.
// It provides insights into API performance and helps identify slow endpoints.
networkRequestEnabled: true,
// Enable or disable automatic crash reporting.
// When enabled, New Relic will automatically capture uncaught exceptions
// and crashes, including stack traces, device info, and app state.
crashReportingEnabled: true,
// Enable or disable interaction tracing.
// Interaction tracing records user interactions such as screen transitions,
// button taps, and custom events. If disabled, these interactions will not
// be captured, though the instrumentation will still occur in the background.
interactionTracingEnabled: true,
// Enable or disable the capture of HTTP response bodies for error traces.
// This applies to HTTP requests that return error codes (e.g., 4xx, 5xx).
// Be cautious with this setting, as it may capture sensitive data.
httpResponseBodyCaptureEnabled: true,
// Enable or disable agent logging for New Relic.
// This includes debug, warning, and error logs generated by the SDK.
// Set to true during development for troubleshooting; set to false in production
// to minimize performance impact.
loggingEnabled: true,
// IOS SPECIFIC
// Enable or disable WebView instrumentation.
// When enabled, New Relic will automatically track web requests made from
// WebView components. This includes network requests and page load performance.
webViewInstrumentation: true,
// Enable or disable capturing print statements as New Relic events.
// When enabled, all print() calls in the app are sent as analytics events.
// Useful for tracking logs without adding explicit New Relic event calls.
printStatementAsEventsEnabled: true,
// Enable or disable automatic HTTP instrumentation.
// When enabled, New Relic will capture HTTP requests and their metadata.
// This includes request URLs, status codes, response times, and error codes.
httpInstrumentationEnabled: true,
// Enable or disable reporting data to government endpoints for FedRAMP compliance.
// Set to true only if your app must adhere to US government data regulations.
fedRampEnabled: false,
// Enable or disable offline data storage.
// When enabled, New Relic will queue data locally if there is no internet connection
// and send it once connectivity is restored. Useful for ensuring data continuity.
offlineStorageEnabled: true,
// IOS SPECIFIC
// Enable or disable background reporting functionality.
// When enabled, New Relic will continue to collect data even when the app is
// running in the background. This may increase resource usage.
backgroundReportingEnabled: false,
// IOS SPECIFIC
// Enable or disable the use of New Relic’s new event system for iOS.
// The new event system provides more stable and consistent event tracking.
// Set to true if you want to use the latest event tracking system.
newEventSystemEnabled: false,
// Enable or disable distributed tracing.
// Distributed tracing allows tracking requests across multiple services,
// enabling end-to-end visibility of complex transaction flows.
// This is critical for identifying performance bottlenecks in microservice architectures.
