环境信息：

操作系统centos7.9，kafka版本为hdp集群中的2.0版本。

Consumer相关参数

使用Kafka自带的kafka-consumer-perf-test.sh脚本进行压测，该脚本参数为：

请添加图片描述

thread：测试时的单机线程数；

fetch-size：抓取数据量；

partition:分区数，主要是和线程复合来测试；

replication:副本数；

througout:我们所需要的吞吐量，单位时间内处理消息的数量，可能对我们处理消息的延迟有影响；

总结

使用kafka自带的kafka-consumer-perf-test.sh脚本对集群消费情况进行压测，根据业务情况设置要测试的messager条数。不同的变量因素，通过修改其中一个变量条件，固定其余变量值，获取对应的吞吐速率。整理不同条件下的指标结果，形成曲线就可以观察具体的消费趋势。
