在k8s 中启动的。
版本：
image: sevennt/naftis-api:0.1.4-rc5

遇到问题：
service中没有数据，个数为0

istio的服务显示正常。

请问需要配置什么吗？还是默认会收集service信息。

@csdnshyang 你的 k8s 中目前有正在运行的服务么，比如 Istio 的示例 Bookinfo。

@shancang 总的服务数和总的 Pod 数，计算时时排除了 istio-system 、kube-system 和 naftis 这三个 namespace，见 #23。

如果这个查询不到服务和 Pod，需要先确认下 k8s 中已经部署了除 istio-system 、kube-system 和 naftis 以外的业务服务，比如 Bookinfo。

k8s集群里有许多服务。

kc get svc --all-namespaces |wc -l
     395
kc get svc -n istio-system |wc -l
      10
kc get svc -n naftis |wc -l
       4
kc get svc -n kube-system |wc -l
       8
kc get svc -n zelda |wc -l
     131

k8s里开了认证，但是应该不是这个问题，毕竟istio相关的svc能扫到。

Bookinfo的我去掉了。但是我自己做了一批spring boot的服务。
就是gated-launch-* 的几个服务。

统计4xx 5xx的流量中可以看到服务的痕迹。

#23 #14 都看了。就是按照时候需不需要做什么配置啊。默认的就能扫到所有的service吗。
mysql那个pod里的表就3张，是不是有问题。

我猜测是安装过程中出现什么问题了，可能是DNS的问题？

@csdnshyang 连不上 MySQL，delete 掉 naftis-api，让它重启下试试。

@sevennt 删除了naftis-api ，结果没有变化。看naftis-api的log，init db success。

服务详情没数据么？可以新开一个 issue。

@sevennt 网络拓扑图看不到，是哪些版本上是有问题的，哪些版本是ok的，其他的数据都是好的。请问能有什么方式查看是那一部分的问题吗？
