我看得见 kafka logs
正在迅速增长,文件系统也在泛滥。
如何更改kafka的设置以减少日志的写入并频繁地旋转这些日志。
文件的位置是- /opt/kafka/kafka_2.12-2.2.2/logs
以及它们的大小-
5.9G server.log.2020-11-24-14
5.9G server.log.2020-11-24-15
5.9G server.log.2020-11-24-16
5.7G server.log.2020-11-24-17
上述文件中的示例日志。

它还向 /opt/kafka/kafka_2.12-2.2.2/kafka.log
.

Kafka用于弹性堆叠。
下面是来自 server.properties
文件。
# A comma seperated list of directories under which to store log files
log.dirs=/var/log/kafka
它的日志文件是
/var/log/kafka

不 DEBUG
在中的文件中启用了级别日志 /opt/kafka/kafka_2.12-2.2.2/config
路径。
我怎样才能确保它不会在 /opt/kafka/kafka_2.12-2.2.2/logs
还有我怎样才能有规律地旋转它们。
谢谢,

log.dirs
是实际的代理存储,而不是进程日志,因此不应在/var/log
与其他进程日志几乎每天6g不是不合理的,但是您可以修改log4j.properties文件,使其与滚动文件appender保持1到2天的距离
一般来说,与任何linux管理任务一样,您都会有单独的磁盘卷来执行
/var/log
,您的操作系统存储,以及任何用于存储服务器数据的专用磁盘—例如/kafka
