我的Kubernetes星系群里有一个正在运行的Kafka吊舱。为了获得prometheus格式的定制度量,我配置了一个jmx\uprometheus\ujavaagent并设计了2255端口。我可以列出localhost:2255/metrics.
问题是,在这之后,我无法列出Kafka的主题。获取以下错误:

bash-4.3# /opt/kafka/bin/kafka-topics.sh --list --zookeeper dz-zookeeper:2181

中止(堆芯转储)
你知道怎么解决这个错误吗?

使用“docker ps”获取kafka broker容器id
然后从命令行对该容器运行kafka命令,方法如下:
docker exec-it containerid/bin/bash-c“kafka\u opts=&&kafka主题--zookeeper 127.0.0.1:2181--list”
更改containerid和zookeeper地址以适合您的环境。

您已经对它进行了设置,这样不仅可以为kafka服务器加载java代理,还可以加载所有命令行工具。您应该更改配置,以便只为服务器加载配置。
