Symptoms



Unisphere GUI 经常出现故障并需要很长时间才会响应。

重新启动管理服务仅能暂时解决问题。

Cause

来自多个虚拟机的 /api/types 请求过多会导致此问题。

Resolution

Unity 管理员必须调查哪些主机向 Unity 阵列发送了这些请求。

作为临时解决方案，可根据文章编号 000490488 重新启动管理服务。

但是，对于永久性解决方案，主机及其各自的虚拟机必须暂停并接受调查，因为它们是问题的原因。

有关此问题的进一步帮助或说明，请联系支持部门并参阅文章编号 000541664。

Additional Information

可以通过查看 access_log 中记录的 /api/types 请求的数量来确认此行为。
可使用以下命令进行验证：
service@spa:~/user# grep -i "GET /api/types" /nas/http/logs/access_log | wc -l
3873

要确定哪些主机负责这些请求，您可以使用下面的命令：
service@spa:~/user# cat /nas/http/logs/access_log | grep -i  "/api/types/loginSessionInfo"
