某局点iMC前台页面无法打开报错“Sorry,Page Not Found”

不涉及

现场从E0506升级到E0605后，后台进程都是正常的，但是前台页面无法打开，报错截图如下：

一般情况下iMC前台页面无法打开都是因为部署监控代理中jserver进程没有启动导致，查看现场部署监控代理jserver进程是启动正常的。此时前台页面打不开的报错信息和以往见到的也不一样，此时需要收集日志进行分析，收集前台imcforeground.log日志信息查看，发现有如下报错：

从日志上看，应该是没有部署性能，检查现场iMC部署情况发现，因为其为新升级的测试环境，主要想使用EPS组件，对于PLAT的一些功能现场暂时不用，其就没有进行对应的部署操作。

PLAT很多功能都是关联在一起的，尤其是像PLAT自己的性能和资源、网元等，不能因为不使用就不对应部署，这是不可以的。现场将性能等功能部署后，再次重启部署监控代理后，前台页面即可访问正常。
