zabbix监控kafka消费

一、Kafka监控的几个指标

1、lag:多少消息没有消费 lag=logsize-offset

2、logsize:Kafka存的消息总数
3、offset:已经消费的消息
Kafka管理工具 介绍: 
 

二、查看zookeeper配置

cat /home/app/zookeeper/zookeeper/conf/zoo.cfg | egrep -v "^$|^#"
clientPort=2181
 

三、查看kafka配置

cat /home/app/kafka/kafka/config/server.properties | egrep -v "^$|^#"
port=9092
host.name=192.168.38.87
zookeeper.connect=192.168.38.87:2181,192.168.38.88:2181
 

四、查看kafka的group name

cd /home/app/zookeeper/zookeeper/bin
./zkCli.sh -server 192.168.38.87:2181
ls /consumers/
lijieGroup
quit
 

五、查看kafka的topic_name

/home/app/kafka/kafka/bin/kafka-run-class.sh kafka.tools.ConsumerOffsetChecker --group=lijieGroup --zookeeper=192.168.38.87:2181
 

六、修改zabbix配置文件

因为zabbix用户不能调用kafka的脚本,需要root用户启动zabbix_agent

vim /opt/zabbix/zabbix_agentd.conf
AllowRoot=1
User=root
Include=/opt/zabbix/zabbix_agentd.conf.d/

vim /opt/zabbix/zabbix_agentd.conf.d/kafka_status.conf
UserParameter=kafka.lag[*],/home/zabbix_scripts/kafka_mon.sh $1 $2 lag
UserParameter=kafka.offset[*],/home/zabbix_scripts/kafka_mon.sh $1 $2 offset
UserParameter=kafka.logsize[*],/home/zabbix_scripts/kafka_mon.sh $1 $2 logsize

chown -R zabbix:zabbix /opt/zabbix/zabbix_agentd.conf.d/kafka_status.conf
chmod -R 777 /opt/zabbix/zabbix_agentd.conf.d/kafka_status.conf
 

七、创建监控脚本

mkdir -pv /home/zabbix_scripts/
vim /home/zabbix_scripts/kafka_mon.sh
#!/bin/bash

kafka_ip="127.0.0.1"
kafka_port=2181
topic_name=$1
group_id=$2
pn=$3
/usr/local/kafka_2.11-0.11.0.0/bin/kafka-run-class.sh kafka.tools.ConsumerOffsetChecker --topic=$topic_name --group=$group_id --zookeeper=$kafka_ip:$kafka_port | grep -v Offset > /tmp/kafka-tp-${topic_name}-${group_id}.info

Offset=0
logSize=0
Lag=0
while read line
do
    Offset=$((${Offset}+`echo $line |awk '{print $4}'`))
    logSize=$((${logSize}+`echo $line |awk '{print $5}'`))
    Lag=$(($Lag+`echo $line |awk '{print $6}'`))
done </tmp/kafka-tp-${topic_name}-${group_id}.info

case $pn in  
    offset|Offset)  
    echo $Offset  
    ;;  
    logsize|logSize)  
    echo $logSize  
    ;; lag|Lag)  
    echo $Lag  
    ;;  
    *)  
    echo Error  
    ;;  
esac 

  

 

  

 
 

八、给脚本和对应文件权限

chown -R zabbix:zabbix /home/zabbix_scripts/kafka_mon.sh
chmod -R 777 /home/zabbix_scripts/kafka_mon.sh

touch /tmp/kafka-tp-RouterOnOfflineStateChange-lijieGroup.info
chmod 777 /tmp/kafka-tp-RouterOnOfflineStateChange-lijieGroup.info
chown zabbix:zabbix /tmp/kafka-tp-RouterOnOfflineStateChange-lijieGroup.info

chmod 777  /home/app/kafka/kafka/bin/kafka-run-class.sh
 

九、重启zabbix

/etc/init.d/zabbix-agent restart
 

十、监控上增加3个键值

kafka.offset[RouterOnOfflineStateChange,lijieGroup]
kafka.logsize[RouterOnOfflineStateChange,lijieGroup]
kafka.lag[RouterOnOfflineStateChange,lijieGroup]
