librdkafka.redist 的日志是什么意思

Question

这是与 Confluent.Kafka 的 librdkafka.redist 依赖项相关的控制台日志的摘录。

我想了解每个竖线分隔的部分是什么。谁能告诉我？我找不到任何关于它的信息。我假设第二列是某种时间戳，第三列是状态，第四列是错误消息。

Answer 1

列：

%3 - 系统日志严重级别。越低越严重。
1602097315.970 - 自纪元以来的秒数。
rdkafka#consumer-2 - 客户端实例名称，它是（可能配置的）client.id、客户端类型（消费者）和增加的运行数字（在当前进程）对于每个新的客户端实例。
[thrd:kfkqaapq0002d.ch.me.com:9092/bootstrap] - 日志从哪个线程发出。应用程序线程将被命名为 thrd:app，所有其他线程名称均为 librdkafka 内部线程。
kfkqaapq0002d.ch.me.com:9092/bootstrap - 日志消息对应的代理。
Failed to resolve 'kfkqaapq0002d.ch.me.com:9092': No such host is known. (after 42ms in state CONNECT) - 日志消息本身。
