as the pic above,if it's not a bug,please note in the docs,because it just make some trouble in runing

when i open the detail page of the service , there is a error like below:

maybe there is something wrong in the i18n file. Please check it, thanks

您好，使用redis做为注册中心，但redis需要密码访问时dubbo.registry.address该如何配置？

The dubbo-admin open issues:
https://github.com/alibaba/dubbo/issues?page=1&q=dubbo-admin+is%3Aopen

navigation: home > governance > applications > appname > services, when i change the tab, only
tab 'services' is normal and other two tabs return 404. You can check what's wrong with it. Thanks

一大堆依赖下载不来,我也是醉了

不好意思，对于一个初学者，看了你的readme, 还有有点懵，这个dubbo-admin可以直接部署到tomcate下面直接访问？请大声给与提点，谢谢

使用dubbo-admin-2.0.0新增一个权重的时候无法成功页面报错，可能是一个组件id设置有问题，下面是详细截图：

1. 新增权重：
   

2. 点击保存报错
   

3. 查看报错的代码
   

4. 查看页面，应该时服务名对应的元素id设置有问题
   

启动报错error：
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://dubbo.apache.org/schema/dubbo]
Offending resource: URL [file:/D:/idea_workspance/incubator-dubbo-ops/dubbo-admin/target/classes/dubbo-admin.xml]

解决办法：
dubbo-admin.xml的dubbo命令空间
http://dubbo.apache.org/schema/dubbo应该改为http://code.alibabatech.com/schema/dubbo

或者

com.alibaba
dubbo
2.6.2

version改为2.6.2以上

system log in new version:

old version:

现在 dubbo-admin的pom是这样的

com.alibaba
dubbo-admin
0.0.1-SNAPSHOT
jar

还是 http://dubbo.apache.org/books/dubbo-admin-book/install/admin-console.html
这个网址应该更新了

能否增加一定的trace支持，并且能根据trace解决一些问题。

比如说根据trace结果发现循环调用：ServiceA -> ServiceB -> ServiceA，
京东因为循环引用出过一次事情，很短时间内发生了几千万次RPC调用。

according to the stacktrace,i modified the class:com.alibaba.dubbo.registry.common.route.ParseUtils.parseQuery method:
changing the line 243 from
if (key != null)
to
if (key != null && !key.equals("contextpath"))

then problem solved!

my question is: is this problem a bug? is my modify right?

建议dubbo-admin做前后台分离和框架改造

1. 建议前端采用angularjs 或是 vue等现代化框架，并进行组件化拆分，使前端工程师更容易参与进来

2. 建议后端改成基于spring boot，并且后端接口遵循restful协议

3. 建议基于spring security实现登陆和权限控制

• 可以轻松的接入公司内部的SSO体系

4. 建议将dubbo数据上报格式规范化，形成一套标准，类似spring boot actuator

5. 能否考虑对docker容器的支持，使dubbo-admin能够很easy地打成docker镜像，和配套服务一起部署进容器内

• 配合其他特性，以实现自动化伸缩，是否有可能？

6. 基于第4点更进一步，能否提供自动化运维支持，通过暴露一套restful服务，该服务可以查询和操作到dubbo内部，类似elasticsearch的restful接口

• dubbo内部是透明的，一切信息都能够通过api查出来

7. 能否提供一些hook，类似git的web hook机制，可以配置一些Lua、Groovy脚本作为是否触发hook的前置filter，在服务状态变化之后，自动推送

• 可以提供一些内置的action

当hook触发之后，可以调到内置action来发邮件、打日志甚至调整服务流量。

8. 能否提供文档化支持

• 像swagger那样，在dubbo-admin里集成一套文档系统，这套文档系统还能用于dubbo调试，类似postman

9.trace和智能网络节点质量分析

• 像zipkin那样，具备链路跟踪能力，并且能够跟进一步，基于链路跟踪上报的数据，分析出整个服务网路中质量较差的节点，帮助开发发现系统瓶颈所在
