Fluent Bit 不从我的 EKS 自定义应用程序发送日志
我正在使用 AWS Opensearch 从所有 Kubernetes 应用程序检索日志。 我有以下 Pod:Kube-proxy
、Fluent-bit
、aws-node
、aws-load-balancer-controller< /code>,以及我所有的应用程序(大约 10 个)。
当 fluent-bit 成功发送来自 Kube-proxy
、Fluent-bit
、aws-node
和 aws-load- 的所有日志时,平衡器控制器
,我的应用程序中没有任何日志被发送。我的应用程序有 DEBUG
、INFO
、ERROR
日志,但没有一个是通过 Fluent Bit 发送的。
这是我流畅的位配置:

I am using AWS Opensearch to retrieve the logs from all my Kubernetes applications.
I have the following pods: Kube-proxy
, Fluent-bit
, aws-node
, aws-load-balancer-controller
, and all my apps (around 10).
While fluent-bit successfully send all the logs from Kube-proxy
, Fluent-bit
, aws-node
and aws-load-balancer-controller
, none of the logs from my applications are sent. My applications had DEBUG
, INFO
, ERROR
logs, and none are sent by fluent bit.
Here is my fluent bit configuration:

最后,我做了两件事解决了我的问题:
然后,我必须删除流畅位弹性搜索索引,然后重新创建它。
事实上,该索引一开始可能不太适合我的 JAVA 日志,并在重新创建后进行了调整。
Finally, I did two things that solved my issue:
Then, I had to delete the fluent-bit Elastic search index, and re-create it.
Indeed, the index was probably not well suited for my JAVA logs at first, and adjusted to it after re-creation.
