Kafka压力测试(自带测试脚本)(单机版)

一、测试目的

本次性能测试在正式环境下单台服务器上Kafka处理MQ消息能力进行压力测试。测试包括对Kafka写入MQ消息和消费MQ消息进行压力测试，根据10w、100w和1000w级别的消息处理结果，评估Kafka的处理性能是否满足项目需求。（该项目期望Kafka能够处理上亿级别的MQ消息）

二、测试范围及方法

2.1 测试范围概述

测试使用Kafka自带的测试脚本，通过命令对Kafka发起写入MQ消息和Kafka消费MQ消息的请求。模拟不同数量级的MQ消息写入和MQ消息消费场景，根据Kafka的处理结果，评估Kafka是否满足处理亿级以上的消息的能力。

2.2性能测试场景设计

2.2.1 Kafka写入消息压力测试

测试场景	MQ消息数	每秒写入消息数	记录大小(单位:字节)
Kafka消息写入测试	10W	2000条	1000
	10W	5000条	1000
	100W	5000条	1000

2.2.2 Kafka消费消息压力测试

测试场景	消费MQ消息数
Kafka消息消费测试	10W
	100W
	1000W

2.3测试方法简要描述

2.3.1测试目的

验证带台服务器上Kafka写入消息和消费消息的能力，根据测试结果评估当前Kafka集群模式是否满足上亿级别的消息处理能力。

2.3.2测试方法

在服务器上使用Kafka自带的测试脚本，分别模拟10w、100w和1000w的消息写入请求，查看Kafka处理不同数量级的消息数时的处理能力，包括每秒生成消息数、吞吐量、消息延迟时间。Kafka消息吸入创建的topic命名为test_perf，使用命令发起消费该topic的请求，查看Kafka消费不同数量级别的消息时的处理能力。

压测命令信息：

测试项	压测消息数（单位:W）	测试命令
写入MQ消息	10	./kafka-producer-perf-test.sh --topic test_perf --num-records 100000 --record-size 1000  --throughput 2000 --producer-props bootstrap.servers=10.150.30.60:9092
	100	./kafka-producer-perf-test.sh --topic test_perf --num-records 1000000 --record-size 2000  --throughput 5000 --producer-props bootstrap.servers=10.150.30.60:9092
	1000	./kafka-producer-perf-test.sh --topic test_perf --num-records 10000000 --record-size 2000  --throughput 5000 --producer-props bootstrap.servers=10.150.30.60:9092
消费MQ消息	10	./kafka-consumer-perf-test.sh --broker-list localhost:9092 --topic test_perf --fetch-size 1048576 --messages 100000 --threads 1
	100	./kafka-consumer-perf-test.sh --broker-list localhost:9092 --topic test_perf --fetch-size 1048576 --messages 1000000 --threads 1
	1000	./kafka-consumer-perf-test.sh --broker-list localhost:9092 --topic test_perf --fetch-size 1048576 --messages 10000000 --threads 1

脚本执行目录：服务器上安装Kafka的bin目录；

三、测试环境

3.1 测试环境机器配置表

主 机	数量	资 源	操作系统
MQ消息服务/处理	1	硬件：1(核)-4(G)-40(G) 软件:Kafka单机(kafka_2.12-2.1.0)	ubuntu-16.04.5-server-amd64

3.2 测试工具

Kafka压测工具

Kafka自带压测脚本

3.3 测试环境搭建

这里仅仅使用单机版的kakfa，为了快速搭建，使用自带的zk。

新建目录

kafka-producer-perf-test.sh 脚本命令的参数解析（以100w写入消息为例）：
--topic topic名称，本例为test_perf
--num-records 总共需要发送的消息数，本例为100000
--record-size 每个记录的字节数，本例为1000
--throughput 每秒钟发送的记录数，本例为5000
--producer-props bootstrap.servers=localhost:9092 （发送端的配置信息，本次测试取集群服务器中的一台作为发送端,可在kafka的config目录，以该项目为例：/usr/local/kafka/config；查看server.properties中配置的zookeeper.connect的值，默认端口：9092）

MQ消息写入测试结果解析：

本例中写入100w条MQ消息为例，每秒平均向kafka写入了4.77MB的数据，大概是4999.375条消息/秒，每次写入的平均延迟为88.83毫秒，最大的延迟为2869毫秒。

4.2.2消费MQ消息

消费MQ消息	消费消息总数 （单位:w）	共消费数据 （单位:M)	每秒消费数据 （单位:M)	每秒消费消息数	消费耗时 （单位:s)
消费MQ消息	10	95.36	137	143899.3	0.695
	100	953.66	177.19	185804.5	5.38
	1000	9536.73	198.25	207878.6	48.11

压测结果

1. 消费10w消息压测结果

./kafka-consumer-perf-test.sh --broker-list localhost: --topic test_perf --fetch-size  --messages  --threads 

注意：此脚本没有--zookeeper选项，参考链接有错误！

必须要执行写入10w消息之后，才能执行上面的命令，否则运行时，会报下面的错误！

[-- ::,] WARN [Consumer clientId=consumer-, groupId=perf-consumer-] Error while fetching metadata with correlation id  : {test_perf=LEADER_NOT_AVAILABLE} (org.apache.kafka.clients.NetworkClient)
WARNING: Exiting before consuming the expected number of messages: timeout ( ms) exceeded. You can use the --timeout option to increase the timeout.

正常输出：

start.time, end.time, data.consumed.in.MB, MB.sec, data.consumed.in.nMsg, nMsg.sec, rebalance.time.ms, fetch.time.ms, fetch.MB.sec, fetch.nMsg.sec
-- :::, -- :::, 95.3674, 23.8121, , 24968.7890, , , 24.2851, 25464.7313

2. 消费100w消息压测结果

./kafka-consumer-perf-test.sh --broker-list localhost: --topic test_perf --fetch-size  --messages  --threads 

输出：

start.time, end.time, data.consumed.in.MB, MB.sec, data.consumed.in.nMsg, nMsg.sec, rebalance.time.ms, fetch.time.ms, fetch.MB.sec, fetch.nMsg.sec
-- :::, -- :::, 954.0758, 49.5264, , 51932.1532, , , 49.6320, 52042.9173

3. 消费1000w消息压测结果

./kafka-consumer-perf-test.sh --broker-list localhost: --topic test_perf --fetch-size  --messages  --threads 

输出：

start.time, end.time, data.consumed.in.MB, MB.sec, data.consumed.in.nMsg, nMsg.sec, rebalance.time.ms, fetch.time.ms, fetch.MB.sec, fetch.nMsg.sec
-- :::, -- :::, 9536.9539, 72.5564, , 76080.8646, , , 72.5779, 76103.4451

kafka-consumer-perf-test.sh 脚本命令的参数为：
--broker-list 指定kafka的链接信息，本例为localhost:9092
--topic 指定topic的名称，本例为test_perf，即4.2.1中写入的消息；
--fetch-size 指定每次fetch的数据的大小，本例为1048576，也就是1M
--messages 总共要消费的消息个数，本例为1000000，100w

以本例中消费100w条MQ消息为例总共消费了954.07M的数据，每秒消费数据大小为49.52M，总共消费了1000421条消息，每秒消费51932.15条消息。

五、结果分析

一般写入MQ消息设置5000条/秒时，消息延迟时间小于等于1ms，在可接受范围内，说明消息写入及时。

Kafka消费MQ消息时，1000W待处理消息的处理能力如果在每秒20w条以上，那么处理结果是理想的。

根据Kafka处理10w、100w和1000w级的消息时的处理能力，可以评估出Kafka集群服务，是否有能力处理上亿级别的消息。

本次测试是在单台服务器上进行，基本不需要考虑网络带宽的影响。所以单台服务器的测试结果，对评估集群服务是否满足上线后实际应用的需求，很有参考价值。
