1 APM概述

在云时代微服务架构下应用日益丰富，纷杂的应用异常问题接踵而来。应用运维面临巨大挑战：

分布式应用关系错综复杂，应用性能问题分析定位困难，应用运维面临如何保障应用正常、快速完成问题定位、迅速找到性能瓶颈的挑战。
应用体验差导致用户流失。运维人员如果无法实时感知并追踪体验差的业务，不能及时诊断应用异常，将严重影响用户体验。
业务系统的应用多、分布广，跨系统、跨区域、跨应用的调用频繁，如何降低应用的管理和运维成本，提升应用运维的效率是迫切需要解决的问题。

华为云应用性能管理服务（Application Performance Management，简称APM）帮助运维人员快速发现应用的性能瓶颈，以及故障根源的快速定位，为用户体验保驾护航。无需修改代码，只需为应用安装一个APM Agent，就能够对该应用进行全方位监控，帮助您快速定位出错接口和慢接口、重现调用参数、发现系统瓶颈，从而大幅提升线上问题诊断的效率。目前支持JAVA、Python、Node.js、Go、Php、C++和.Net应用。

2 部署

2.1 部署JAVA示例应用

示例应用包含4个服务，ui服务是入口，其接口如下：

GET /start
GET /readtimeout

示例应用运行在名称为demo的namespace中，因此先创建它：

kubectl create ns demo

demo应用的yaml如下，直接apply到kubernetes集群。
