概述
上次 升级vRealize Operations 版本后，发现集成的VMware Horizon 适配器全部出现了告警，同时报错“
Failed to Test adapter instance. Reason - Unknown Error. Please contact support team.” 如下图所示
日志分析
查了好多KB资料都未能查到有效的解决方案，于是去查看了下日志，收集到一些有帮助的日志

果不其然，可见从8.14.1开始，就不支持 VMware Aria Operations Management Pack for VMware Horizon 1.2.2，同时官网的建议是因版本2.7.1有问题，建议只升级到2.7的版本。
