Kafka logs in go service
问题
我需要用于调试的Kafka消费者日志。我按照以下步骤进行操作：
chanLogs := make(chan confluentkafka.LogEvent)go func() {for {logEv := <-chanLogslogger.Debug("KAFKA: " + logEv.String())}}()configMap["go.logs.channel.enable"] = trueconfigMap["go.logs.channel"] = chanLogsconsumer, err := confluentkafka.NewConsumer(&configMap)err := consumer.SubscribeTopics(Topics, nil)
但是我从来没有得到过一行日志。我尝试使用kafka chan (consumer.Logs())，结果也是一样。我做错了什么？
更新
在初始帖子中，我错误地设置了参数名称。正确的参数名称是go.logs.channel.enable。但有时这仍然不起作用。
英文:
I need kafka consumer logs for debug. I do the following:
chanLogs := make(chan confluentkafka.LogEvent)go func() {for {logEv := <-chanLogslogger.Debug("KAFKA: " + logEv.String())}}()configMap["go.logs.channel.enable"] = trueconfigMap["go.logs.channel"] = chanLogsconsumer, err := confluentkafka.NewConsumer(&configMap)err := consumer.SubscribeTopics(Topics, nil)
And I never get a line. I tried it with kafka chan (consumer.Logs()) with the same result. What I do wrong?
UPD
In initial post I wrongfully set parameter name. The correct one is go.logs.channel.enable. But sometimes this still don't work.

根据文档的描述，你应该启用该功能：
go.logs.channel (chan kafka.LogEvent, nil) - 将日志转发到应用程序提供的通道，而不是 Logs()。需要设置 go.logs.channel.enable=true。
所以你需要修改你的代码如下：
configMap["go.logs.channel"] = chanLogsconfigMap["go.logs.channel.enable"] = trueconsumer, err := confluentkafka.NewConsumer(&configMap)
英文:
As described in the doc, you should enable that feature:
go.logs.channel.enable (bool, false) - Forward log to Logs() channel.go.logs.channel (chan kafka.LogEvent, nil) - Forward logs to application-provided channel instead of Logs(). Requires go.logs.channel.enable=true.
So change your code like:
configMap["go.logs.channel"] = chanLogsconfigMap["go.logs.channel.enable"] = trueconsumer, err := confluentkafka.NewConsumer(&configMap)

解决方案是添加以下代码：
configMap["debug"] = "all"
