Trace Configuration¶

Trace Initialization Configuration¶

let traceConfig: FTTraceConfig = {
  enableNativeAutoTrace: true,
};
await FTReactNativeTrace.setConfig(traceConfig);

Field	Type	Required	Description
sampleRate	number	No	Sampling rate, value range [0,1]. 0 means no collection, 1 means full collection. Default value is 1
traceType	enum TraceType	No	Trace type, default is `TraceType.ddTrace`. Supports `TraceType.ddTrace`, `TraceType.zipkinMulti`, `TraceType.zipkinSingle`, `TraceType.traceparent`, `TraceType.skywalking`, `TraceType.jaeger`
enableLinkRUMData	boolean	No	Whether to link with `RUM` data, default is `false`
enableNativeAutoTrace	boolean	No	Whether to enable native network auto-tracing for iOS `NSURLSession` and Android `OKhttp`. Since React Native network requests are implemented using system APIs on iOS and Android, enabling this allows all React Native request data to be traced together

Tracer Network Trace¶

When initializing the SDK with Trace configuration, automatic network tracing can be enabled. Custom collection is also supported.

Usage¶

/**
 * Get trace HTTP request header data.
 * @deprecated use getTraceHeaderFields() replace.
 */
getTraceHeader(key: String, url: String): Promise<object>;

/**
 * Get trace HTTP request header data.
 */
getTraceHeaderFields(url: String, key?: String): Promise<object>;

Example¶

import { FTReactNativeTrace } from '@cloudcare/react-native-mobile';
async function getHttp(url: string) {
  const key = Utils.getUUID();
  const traceHeader = await FTReactNativeTrace.getTraceHeaderFields(url);
  const fetchOptions = {
    method: 'GET',
    headers: Object.assign(
      {
        Accept: 'application/json',
        'Content-Type': 'application/json',
      },
      traceHeader,
    ),
  };
  fetch(url, fetchOptions);
}
