Log Configuration¶

This document describes the Log initialization configuration and log printing instructions for the C++ SDK.

Initialize Log¶

FTLogConfig lpc;
// std::vector<LogLevel> llf;
// llf.push_back(LogLevel::ERR);
// lpc.setLogLevelFilters(llf);
lpc.setEnableCustomLog(true)
   .setEnableLinkRumData(true);
sdk->initLogWithConfig(lpc);

Field	Type	Required	Description
`setSamplingRate`	float	No	Sampling rate range `[0,1]`. `0` means no collection, `1` means full collection. Default value is `1`.
`addGlobalContext`	dictionary	No	Add tag data. For rules, please read Custom Tags.
`setLogLevelFilters`	array	No	Set log level filters. Not set by default.
`setEnableCustomLog`	bool	No	Whether to upload custom logs. Default is `false`.
`setEnableLinkRUMData`	bool	No	Whether to associate with RUM data. Default is `false`.
`setLogCacheDiscardStrategy`	LogCacheDiscard	No	Default is `LogCacheDiscard::DISCARD`. `DISCARD` discards the appended data, `DISCARD_OLDEST` discards the oldest data.

Log Printing¶

/**
 * Upload user logs to DataKit
 *
 * @param content Log content
 * @param level   Log level
 */
void addLog(std::string content, LogLevel level);

Example:

sdk->addLog("this\\is a \"test\" log", LogLevel::info);
