我试图理解每个管道分隔的部分是什么。有人能告诉我吗？我找不到关于它的任何信息。我假设第2列是某种时间戳，第3列是状态，第4列是错误消息。

列：

• %3

  -系统日志严重性级别。越低越严重

• 1602097315.970

  -从纪元开始的秒数

• rdkafka#consumer-2

  -客户端实例名称，它是（可能已配置的）

  client.id

  、客户端类型（consumer）和每个新客户端实例（在当前流程中）增加的运行编号的组合

• [thrd:kfkqaapq0002d.ch.me.com:9092/bootstrap]

  -日志从哪个线程发出。应用程序线程将命名为

  thrd:app

  ，所有其他线程名称都是librdkafka内部线程

• kfkqaapq0002d.ch.me.com:9092/bootstrap

  -日志消息对应的代理

• 未能解析“kfkqaapq0002d.ch.me.com:9092”：未知此类主机。（连接状态42毫秒后）

  -日志消息本身
