Question

我正在尝试创建一个多线程的Boost logger文件。那可以做以下事情：

写信给目录。
可以在午夜或rache最大文件大小时旋转文件。
需要检查是否有足够的空间将文件刻录到光盘上。
最多可以创建10个日志文件。

我使用的增强版本是1.65.1。

问题是：

提高了具有相同内容示例的2个文件箱： BioEngine_17145_Mon_Nov_11_15_32_40_2019和BioEngine_11_11_2019_15_32_40_0.log
没有一个文件在我需要的目标目录中创建。文件中包含要在哪里运行的文件。
最大文件数不起作用，我分配的文件数超过10个。

我找不到我在做什么。感谢您提供以下帮助代码。

在将任何日志写入文件之前，从Init函数调用记录器Init函数。

 void LoggerInit(string& log_dir)
{
    boost::shared_ptr< file_sink > sink(new file_sink(
        boost::log::keywords::target = log_dir,
        boost::log::keywords::file_name = "BioEngine_%d_%m_%Y_%H_%M_%S_%N.log",
        boost::log::keywords::rotation_size = 10 * 1024 * 1024,
        boost::log::keywords::max_size = 10 * 1024 * 1024,
        boost::log::keywords::min_free_space = 100 * 1024 * 1024,
        boost::log::keywords::max_files = 10,
        keywords::time_based_rotation = sinks::file::rotation_at_time_point(0, 0, 0),
        boost::log::sinks::file::scan_method::scan_matching,
        boost::log::keywords::open_mode = std::ios_base::app,
        boost::log::keywords::auto_flush = true
    ));


    sink->locked_backend()->set_file_collector(boost::log::sinks::file::make_collector(
        boost::log::keywords::target = log_dir,                      /*< the target directory >*/
        boost::log::keywords::max_size = 10 * 1024 * 1024,          /*< maximum total size of the stored files, in bytes >*/
        boost::log::keywords::min_free_space = 100 * 1024 * 1024,   /*< minimum free space on the drive, in bytes >*/
        boost::log::keywords::max_files = 10                       /*< maximum number of stored files >*/
    ));

    sink->set_formatter(
        expr::stream
        << "[" << boost::log::expressions::attr<boost::log::process_id>("ProcessID")
        << "][" << boost::log::expressions::attr<boost::log::thread_id>("ThreadID")
        << "][" << expr::format_date_time< boost::posix_time::ptime >("TimeStamp", "%d-%m-%Y %H:%M:%S.%fz") << "]"
        << "[" << logging::trivial::severity << "]"
        << expr::smessage
    );


    sink->locked_backend()->scan_for_files(boost::log::sinks::file::scan_method::scan_matching, true);

    logging::core::get()->add_sink(sink);



    logging::core::get()->set_filter
    (
        logging::trivial::severity >= logging::trivial::info
    );
}

我解决了这个问题，现在只有1个日志写入到进程工作目录，并且在文件旋转后将其旋转到boost :: log :: keywords :: target

void LoggerInit(string& log_dir)
{
    logging::add_common_attributes();
    boost::shared_ptr< logging::core > core = logging::core::get();

    logging::add_file_log
    (
            keywords::file_name =   "BioEngine_%d_%m_%Y__%H_%M_%S_%N.log",
            keywords::rotation_size = 10 * 1024 * 1024,
            boost::log::keywords::target = log_dir,
            boost::log::keywords::min_free_space = 100 * 1024 * 1024,
            boost::log::keywords::max_size = 100 * 1024 * 1024,
            keywords::time_based_rotation = sinks::file::rotation_at_time_point(0, 0, 0),
            boost::log::keywords::scan_method = boost::log::sinks::file::scan_matching,
            keywords::auto_flush = true,
            keywords::max_files = 10,
            keywords::format =
            (
                    expr::stream
                    << "[" << boost::log::expressions::attr<boost::log::process_id>("ProcessID")
                    << "][" << boost::log::expressions::attr<boost::log::thread_id>("ThreadID")
                    << "][" << expr::format_date_time< boost::posix_time::ptime >("TimeStamp", "%d-%m-%Y %H:%M:%S.%f") << "]"
                    << "[" << logging::trivial::severity << "]"
                    << expr::smessage
                    )
    );


    logging::core::get()->set_filter
    (
        logging::trivial::severity >= logging::trivial::info
    );
}
