博客服务器一直用着NodeQuery、UptimeRobot和Netdata，各司其职。 虽然Netdata的功能确实齐全，但万一服务器GG了，没恢复前，是无法查阅数据，最多因为GG前有邮件提醒，有预警，而且很多数据其实并不需要去看。 使用Amplify的原因，主要是UI高大上（但不支持移动端是个糟点，希望尽快完善）、开源、轻便，主要服务（Nginx、PHP、MySQL）的参数及系统资源监测较齐，并且完全以图表显示（更容易发现瓶颈和问题）。而且可以定制预警类型，完全可以取代Netdata并补了NodeQuery的不足（NQ只能对CPU、MEM、DISK做预警）。 虽说预警数量有限制，但完全够用。最重要的是，出现问题时，起码我在外部，能看到一些大概问题。 另外一点比较好的是Analyzer功能，（因为与Nginx深度整合）能看到Nginx的一些优化建议和问题提醒。不过貌似优化得不错，所以并没有特别需要改的。 简单来说，Nginx Amplify是个较为全面的系统监测工具。 而且之前提到给Amplify提交的两个问题，Ngi
