<p>监视工具捕获，分析和显示Web应用程序执行信息。每个应用程序在Web堆栈的所有层都可能出现问题。监控工具通过展示帮助开发人员和运营团队响应并修复问题。</p>
<p>捕获和分析有关生产环境的数据对于主动处理Web应用程序的稳定性，性能和错误至关重要。</p>
<p>监视和日志记录的目的非常相似，它们有助于诊断应用程序的问题并帮助调试。主要差异为日志基于事件触发，而监视是被动的背景数据集合。</p>
<p>例如发生错误时，通过异常处理程序中的代码显式记录该事件。同时，监视代理程序对代码进行检测，并且不仅收集有关已记录异常的数据，还收集有关函数和方法性能的数据。</p>
<p>操作系统和网络的监控关注: CPU、内存和磁盘利用率，网络带宽和延迟</p>
<p>应用程序级别监视包含几个方面。 基于应用程序是重读，重写还是受到快速波动的影响而有所不同。涉及应用程序警告和错误(500级HTTP错误)、应用代码性能、模板渲染时间、浏览器渲染应用程序的时间、数据库查询性能等。</p>

<p>A practical introduction to the world of machine learning and image processing using
OpenCV and Python 使用OpenCV和Python对机器学习和图像处理世界的实用介绍</p>
<p><img alt="image.png" src="https://upload-images.jianshu.io/upload_images/12713060-b6e6d51b3d273984.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240"></p>
<p>机器学习不再仅仅是一个流行语，它就在我们身边：从保护您的电子邮件到自动标记图片中的朋友，到预测您喜欢的电影。计算机视觉是当今最令人兴奋的机器学习应用领域之一，深度学习驱动创新系统，如自动驾驶汽车和谷歌的DeepMind。</p>
<p>OpenCV位于这些主题的交叉点，为经典以及最先进的计算机视觉和机器学习算法提供了一个全面的开源库。结合Python Anaconda，您可以访问您可能要求的所有开源计算库。</p>
<p>OpenCV的机器学习首先向您介绍统计学习的基本概念，例如分类和回归。一旦涵盖了所有基础知识，您将开始探索各种算法，如决策树，支持向量机和贝叶斯网络，并学习如何将它们与其他OpenCV功能相结合。随着本书的进展，您的机器学习技能也将如此，直到您准备好接受当今最热门的话题：深度学习。</p>
<p>在本书的最后，您将准备好通过构建现有的源代码或从头开发自己的算法来解决您自己的机器学习问题！</p>

<p>唐朝期间，唐太宗患病，太医们束手无策。于是，太宗传旨召孙思邈进宫。孙思邈为唐太宗诊过脉，开了药方。一剂下去，唐太宗的病不见起色，后来又服一剂，仍不见效。当时唐太宗没有责怪他，让他先回家去。</p>
<p>孙思邈心里很不痛快，行走了半天，他来到一座山下，向山民讨口水喝。这户山民只有姐妹俩，以卖药材为生。她们对这位远来的客人很热情，姐姐用黄色花为他冲了一碗金花茶，妹妹用白色花为他冲了一碗银花茶。孙思邈每样茶喝一口，觉得味甘清淡，止渴清热，就说 “这两种花都可以入药。”</p>
<p>姐妹二人听罢，笑了起来。姐姐解释说 “这两种药是同一种药，刚开时白色，盛开时变黄，它叫金银花。莫说你，就是孙思邈也不认真假药呢，这次他在万岁爷面前丢尽了面子。我们进城卖药，那些太监把我们的药全都拿走，只给一点点钱。我们气不过，就用假药骗他们，为此连孙思邈也治不好万岁爷的病。”</p>
<p>孙思邈听罢，恍然大悟，当下 …</p>

<p>话说古时泰山脚下有个村子，村里有位何员外。何员外晚年生得一女，取名欢喜。这姑娘生得聪明美貌，何员外夫妻俩视如掌上明珠。欢喜18岁那年清明节到南山烧香，回来得了一种难治的病，精神恍惚，茶饭不思，一天天瘦下去，请了许多名医，吃了很多药，都不见效。因此，何员外贴出告示，重金酬谢能够医治小姐疾病者。</p>
<p>西庄有一位秀才虽穷，却长得眉清目秀，天资聪慧，除了文才过人，还精通医道。苦于无钱进京赶考。看到告示，秀才便揭榜进门。见到小姐，秀才即全然知晓病情，原来那日小姐南山烧香，与秀才邂逅，喜欢上他了，回家后日夜相思，此番见到秀才，病就好了一大半。于是，在诊脉后秀才说：“这位小姐是因心思不遂，忧思成疾，情志郁结所致。”又说南山上有一棵树，人称“有情树”，羽状复叶，片片相对，而且昼开夜合，其花如丝，清香扑鼻，可以清心解郁，定志安神 …</p>

<p>据说，“吴茱萸”在春秋时候原名“吴萸”。它产在吴国，是一味止痛良药。</p>
<p>当时，吴国和邻近的楚国相比，还算小国，小国就得向大国进贡。这一年，吴国的贡品之中就有吴萸。谁想楚王一见，竟大发雷霆：</p>
<p>“小小的吴国，胆敢把以国命名的东西当贡品，这不是看不起堂堂的楚国吗？拿回去，不收！”</p>
<p>吴国的使者愣住了。</p>
<p>这时，有位姓朱的楚国大夫，急忙对楚王说：</p>
<p>“吴萸能治胃寒腹疼，还能止吐止泄。吴王听说大王有腹痛的老病，才选来进贡的。如果拒绝接受，那不就伤了两国的和气吗？”</p>
<p>“胡说，”楚王喝道，“我用不着什么‘吴萸’！我们的国家也不需要！”</p>
<p>吴国的使臣又羞又气，退出王宫。朱大夫追出来说：</p>
<p>“请你不要生气。就把吴萸留给我吧。楚王早晚会用上它的。”</p>
<p>吴使就把吴萸给了朱大夫。朱大夫拿到家中，栽在院内，还命人精心管理。</p>
<p>吴使回国后，吴王一听楚王这么无礼，就同楚国断了交。</p>
<p>几年过后 …</p>
