Log Configuration¶

Log Initialization Configuration¶

let logConfig: FTLogConfig = {
  enableCustomLog: true,
  enableLinkRumData: true,
};
await FTReactNativeLog.logConfig(logConfig);

Field	Type	Required	Description
sampleRate	number	No	Sampling rate, value range [0,1]. 0 means no collection, 1 means full collection. Default is 1.
enableLinkRumData	boolean	No	Whether to associate with `RUM`.
enableCustomLog	boolean	No	Whether to enable custom logs.
logLevelFilters	Array	No	Log level filters.
globalContext	NSDictionary	No	Add custom tags for Log. For addition rules, please refer to here.
logCacheLimitCount	number	No	Maximum number of log entries allowed in local cache [1000,). Larger logs mean greater disk cache pressure. Default is 5000.
discardStrategy	enum FTLogCacheDiscard	No	Sets the discard rule when the log limit is reached. Default is `FTLogCacheDiscard.discard`. `discard` discards appended data, `discardOldest` discards oldest data.

Logger Log Printing¶

Currently, the log content is limited to 30 KB. Characters exceeding this limit will be truncated.

Usage¶

/**
 * Outputs a log.
 * @param content Log content
 * @param logStatus Log status
 * @param property Log context (optional)
 */
logging(content: String, logStatus: FTLogStatus | String, property?: object): Promise<void>;

Example¶

import { FTReactNativeLog, FTLogStatus } from '@cloudcare/react-native-mobile';

// logStatus: FTLogStatus
FTReactNativeLog.logging('info log content', FTLogStatus.info);

// logStatus: string
FTReactNativeLog.logging('info log content', 'info');

Log Levels¶

Method Name	Meaning

FTLogStatus.warning	Warning
FTLogStatus.error	Error
FTLogStatus.critical	Critical
FTLogStatus.ok	Ok
