将 filebeat [@timestamp] 从 UTC 转换为本地时区

Question

我正在尝试从 KOPS 集群中正在运行的 pod 收集日志。我在 KOPS 集群中运行 filebeat DemonSet 以从我的 pod（应用程序）收集日志，然后将这些日志发送到集群外部，logstash 服务接受它们并将它们保存到文件中。

我注意到即使我的所有节点和 Pod 都在 SGT 时区运行，filebeat 总是生成带有 UTC 时间戳的日志。

我在 filebeat 处理器中设置了 add_locale，但它没有帮助。

• 添加语言环境： 格式：偏移量

节点时区

pod 时区

完成文件beat-kubernetes.yaml

filebeat 输出日志

Answer 1

不幸的是，我没有足够的声誉来添加评论，因此将其发布为答案。 following reference doc 提到：

处理器为每个事件添加一个 event.timezone 值。

因此，日志时间戳本身可能不会转换为本地时区，但它会在事件日志中添加额外的字段来表示时区，并且可用于通过使用日志的应用程序来格式化日志。
