<h1 id="监控"><a class="header" href="#监控">监控</a></h1>
|
|
|
<p>监控是一个很大的领域，大到老板、前端开发、后端开发理解的监控可能都不相同。</p>
|
|
|
<ul>
|
|
|
<li>老板眼中的监控：业务大数据实时展示</li>
|
|
|
<li>前端眼中的监控：手机 APP 收集上来的异常、崩溃、用户操作日志等</li>
|
|
|
<li>后端眼中的监控：请求链路跟踪、一段时间内的请求错误率、QPS 过高、异常日志等</li>
|
|
|
</ul>
|
|
|
<p>正是因为这些复杂性，导致很多同学难以准确的说出监控到底是什么。</p>
|
|
|
<p>下面，我们将试图解释清楚监控的概念，并引入一个全新的概念：可观测性。</p>
