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

从日志中看到大部分错误是来自“HorizonAdapter”并且它当前的为“1.2.2.0”，设想，有没有可能是它的版本不兼容呢？于是去查了一下 VM软件产品互操作性矩阵，结果如下：

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。

升级HorizonAdapter

升级VMware Aria Operations Management Pack for VMware Horizon 2.7 补丁文件：horizonadapter-2.7.0-22591477.pak 的过程和 升级vRealize Operations 一样，只需要将它上传并安装即可。

验证

通过编辑现有 VMware Horizon 适配器，点击 “验证连接”
