Question

我想使用boost :: log让我的loadtest应用程序登录到不同的文件和控制台。每个工作线程（表示连接到要测试的服务器的一个用户）应记录线程日志并记录对失败的呼叫日志的失败调用。我试图通过使用过滤器实现这一点。

目标是：

=> All logs with severity = lower than "INFO" will be discarded
=> All log records having the attribute "global" go to ./logs/loadtest.log AND to console
=> All log records having the attribute "thread" go to ./logs/thread.log AND to console
=> All log records having the attribute "faileCalls" go to ./logs/failedCalls.log AND to console

这是我的初始化代码：

void initLogging()
{
boost::shared_ptr<boost::log::core::basic_core> core = boost::log::core::get();

// Construct the sinks for our global log file and for console
typedef boost::log::sinks::asynchronous_sink<boost::log::sinks::text_ostream_backend> text_sink;

// global log file
boost::shared_ptr<text_sink> sinkLoadtest = boost::make_shared<text_sink>();
sinkLoadtest->locked_backend()->add_stream(boost::make_shared<std::ofstream>("./logs/loadtest.log", std::ios::app));
sinkLoadtest->locked_backend()->auto_flush(true);
sinkLoadtest->set_filter(boost::log::filters::has_attr("global"));
core->add_sink(sinkLoadtest);

// console
boost::shared_ptr<text_sink> sinkConsole = boost::make_shared<text_sink>();
boost::shared_ptr<std::ostream> stream(&std::clog, boost::log::empty_deleter());
sinkConsole->locked_backend()->add_stream(stream);
sinkConsole->locked_backend()->auto_flush(true);
core->add_sink(sinkConsole);


// thread dependent logging (one file per workthread)
    sinkThread = boost::make_shared<text_sink>();
sinkFailedCalls = boost::make_shared<text_sink>();

    sinkThread->locked_backend()->add_stream(boost::make_shared<std::ofstream>("./logs/thread.log"), std::ios::app));
    sinkFailedCalls->locked_backend()->add_stream(boost::make_shared<std::ofstream>("./logs/failedCalls.log", std::ios::app));

    sinkThread->set_filter(boost::log::filters::has_attr("thread"));
    sinkFailedCalls->set_filter(boost::log::filters::has_attr("failedCalls"));

    core->add_sink(sinkThread);
    core->add_sink(sinkFailedCalls);

    // set global severity level
    core->set_filter(boost::log::filters::attr<boost::log::trivial::severity_level>("Severity") >= boost::log::trivial::info);
}

这是我的问题：使用哪些宏来传递Severity level PLUS我的一个自定义过滤器属性？

获取记录器的最佳方法是什么？ Alwas从核心获得它或者有一个成员变量＆＃34; logger＆＃34;？我需要它是线程安全的。

提前感谢您的努力！

最佳

//编辑：如果这样的宏提供使用流媒体运营商

将会很棒

Answer 1

您必须使用BOOST_LOG_STREAM_WITH_PARAMS或等效的BOOST_LOG_WITH_PARAMS

Boost :: Log - 记录严重性和自定义过滤器属性？使用哪个宏？
