Dusage.rst102 与监测相关的信息包括请求规格和结果被称为DAMON上下文。DAMON用一个叫做kdamond的内核线程
107 ``0`` 到 ``N-1`` 的子目录数量。每个目录代表每个kdamond。
112 在每个kdamond目录中，存在两个文件（``state`` 和 ``pid`` ）和一个目录( ``contexts`` )。
114 读取 ``state`` 时，如果kdamond当前正在运行，则返回 ``on`` ，如果没有运行则返回 ``off`` 。
115 写入 ``on`` 或 ``off`` 使kdamond处于状态。向 ``state`` 文件写 ``update_schemes_stats`` ，
116 更新kdamond的每个基于DAMON的操作方案的统计文件的内容。关于统计信息的细节，请参考
118 ``state`` 文件，为kdamond的每个基于DAMON的操作方案，更新基于DAMON的操作方案动作的尝试区域目录。
119 将`clear_schemes_tried_regions`写入`state`文件，清除kdamond的每个基于DAMON的操作方案的动作
123 如果状态为 ``on``，读取 ``pid`` 显示kdamond线程的pid。
125 ``contexts`` 目录包含控制这个kdamond要执行的监测上下文的文件。

121 In each kdamond directory, two files (``state`` and ``pid``) and one directory
124 Reading ``state`` returns ``on`` if the kdamond is currently running, or
125 ``off`` if it is not running. Writing ``on`` or ``off`` makes the kdamond be
126 in the state. Writing ``commit`` to the ``state`` file makes kdamond reads the

143 If the state is ``on``, reading ``pid`` shows the pid of the kdamond thread.
