Kafka 模块
编辑Kafka 模块
编辑这是 Kafka 模块。
默认的度量集为 consumergroup
和 partition
。
如果在 Kafka 集群中配置了授权,则 Metricbeat 用户需要以下 ACL:
- READ 主题,用于要监控的主题
- DESCRIBE 组,用于要监控的组
例如,如果 stats
用户用于 Metricbeat 来监控所有主题和所有消费者组,则可以使用以下命令授予 ACL:
kafka-acls --authorizer-properties zookeeper.connect=localhost:2181 --add --allow-principal User:stats --operation Read --topic '*' kafka-acls --authorizer-properties zookeeper.connect=localhost:2181 --add --allow-principal User:stats --operation Describe --group '*'
兼容性
编辑此模块已通过 Kafka 0.10.2.1、1.1.0、2.1.1 和 2.2.2 测试。
Broker、Producer、Consumer 度量集需要 Jolokia 来获取 JMX 指标。请参阅链接以了解 Jolokia 的兼容性说明。
用法
编辑Broker、Producer、Consumer 度量集需要 Jolokia 来获取 JMX 指标。请参阅这些度量集的文档,了解如何使用 Jolokia。
仪表盘
编辑Kafka 模块附带一个预定义的仪表盘。例如
Kafka 模块支持在 模块 中描述的标准配置选项。这是一个示例配置
