即使数据在 Elasticsearch 中，Graylog2 Web 界面也不显示 logs/messages
Graylog2 web interface doesn't show logs/messages even though the data is in Elasticsearch
所以，我已经安装了 Graylog2、Elasticsearch 和 MongoDB。
它们全部 运行 在同一台机器上。问题是日志收集工作正常，我可以通过查询 Elasticsearch 来验证这一点，但 Graylog2 Web 界面不显示任何消息。
这是网络界面日志：

那里也没有什么不寻常的。但它不在前端显示数据。
但是在右侧，它显示的是总事件数。
我在互联网上找不到任何正在讨论的类似问题。
我正在使用 Graylog2 0.20.2 和 Elasticsearch 0.90.7。
其实我才发现，当我从下拉选项select 'All'中显示所有数据时。
看起来这是一个时区问题。所以，安装没有问题。
