3、es集群状态：

Aable7 · 2020年3月25日

huanggze 我现在起了4个data节点，1个master节点，timeout这种报错没了，但是还是前端还是没显示log。看es集群的状态，也没定位出原因来~

Aable7 · 2020年3月25日

able7
页面容器的日志也不刷新

huanggze · 2020年3月25日

able7

fluent bit 报错 unavailable_shards_exception。是shard 的有问题？

curl localhost:9200/_cat/shards

huanggze · 2020年3月25日

able7 是的。因为 -2020.03.25 今天的 index 没创建成功

able7 明天约个时间帮你远程看下？什么时候方便呢？

Aable7 · 2020年3月26日

huanggze 可以啊，随时等着在。我给你发邮件了

able7 好的，那我明天10点邮件你吧

再次感谢kubesphere@yunify.com 大佬支持。在此整理下排错思路。
1、首先根据以下issue查看相关配置是否有误，比如说日志的路径需要根据实际情况修改；我这边就是/data1/docker/containers这个路径：
https://github.com/kubesphere/kubesphere/issues/680
2、查看es集群的状态是否正常，符合预期。
由于我这边k8s内服务非常多，产生的日志量也非常大，1 master/2 data节点部署方式，确实撑不住，一堆GC报错，后面调整成1master/5 data节点，并且修改es集群的相关jvm参数后，集群状态是正常的

curl http://10.106.215.141:9200/_cluster/health?pretty=true
curl http://10.106.215.141:9200/_cat/indices
curl http://10.106.215.141:9200/_cat/shards
curl http://10.106.215.141:9200/ks-logstash-log-2020.03.27/_search

通过以上命令我简单查看集群是否ok

3、我这边确保以上2个问题都得到解决的情况下，前端仍然显示不了日志，然后去查看api的问题：
因为kubesphere ks-apiserver只是封装es的API接口，我们进入ks-apiserver里面查看
apk add curl
curl localhost:9090/kapis/logging.kubesphere.io/v1alpha2/cluster
接口返回是空的。

4、后面让开发去单步调试代码，发现开发合ks-apiserver代码有些问题，我们这边针对kubesphere做了一些定制开发，代码合并出现问题，导致ks-apiserver出了问题，现在已解决。

tips: kubesphere-config cm里面关于logging的配置，也需要仔细检查，不能出现配置错误。
以上就是排查过程。感谢kubesphere@yunify.com支持

huanggze Hi_{我最近新安装的v3}.1.1的，docker路径也是放在/data盘，按照你们说的方法试了一篇还是不行，而且新版的kubersphere和fluent-operator配置上应该有些差异，麻烦帮忙看下!

fluent-bit日志：

inputs crd手动改和docker路径（/data/lib/docker/containers）对应的配置：

fluent-bit挂载的路径

zwz · 2021年9月9日

zwz 是外接es

V3.2.1 也遇到同样问题，es日志显示页面为空
