Zabbix-Monitoring-Kafka

Zabbix-Monitoring Kafka集群 Brokers服务,Kafka Consumer Monitoring

Preface:

The company let me deal with Hadoop and related services monitoring, alarm here mainly kafka cluster services. Here I also read a few kafka related articles, good text posted out:

Infoq kafka entry understanding Introduction to kafka working principle Several of our main features in Kafka are very satisfying to our needs: scalability, data partitioning, low latency, and the ability to handle a large number of different consumers.

And here I want to help the BI team to achieve Kafka full control. Two points:

1. Monitor Kafka Brokers service
2. Monitor Kafka Lag count

For Kafka monitoring, there are ready-made open source software, and in our company also used for some time, there are two options. Our company uses the third option.

Kafka three monitoring tools table of Contents

  1, Kafka Web Conslole
  2, Kafka Manager
  3, KafkaOffsetMonitor

• First you have to install zabbix-java-gataway

    yum install -y zabbix-java-gataway

• Configuring zabbix-java-gataway

    mcedit /etc/zabbix/zabbix_java_gateway.conf

Uncoment and set START_POLLERS=10

• Configuring zabbix-server

  mcedit /etc/zabbix/zabbix_server.conf

Uncoment and set to StartJavaPollers=5 Change IP for JavaGateway=IP_address_java_gateway

• Restart zabbix-server

/etc/init.d/zabbix-java-gataway restart

• Add to autorun zabbix-java-gataway

 chkconfig --level 345 zabbix-java-gataway on

• Start zabbix-java-gataway

/etc/init.d/zabbix-java-gataway start

• Kafka configuration

    cd /opt/kafka/bin
    mcedit kafka-run-class.sh

change from

# JMX settings
if [ -z "$KAFKA_JMX_OPTS" ]; then
KAFKA_JMX_OPTS="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -   Dcom.sun.management.jmxremote.ssl=false "
fi

to

# JMX settings
if [ -z "$KAFKA_JMX_OPTS" ]; then
KAFKA_JMX_OPTS="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=12345 -    Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false "
fi

• Add Kafka as service

• Add to /etc/supervisord.conf that lines

  [program:kafka] command=/opt/kafka/bin/kafka-server-start.sh /opt/kafka/config/server.properties directory=/opt/kafka/ autostart=true autorestart=true stopasgroup=true startsecs=10 startretries=999 log_stdout=true log_stderr=true logfile=/var/log/kafka/supervisord-kafka.out logfile_maxbytes=20MB logfile_backups=10

• Restart supervisor

/etc/init.d/supervisord restart

Zabbix configuration

#Upload scripts for discovery JMX

 git clone https://github.com/yangcvo/Zabbix-Monitoring-Kafka.git
 cd /kafka
 cp jmx_discovery /etc/zabbix/externalscripts
 cp JMXDiscovery-0.0.1.jar /etc/zabbix/externalscripts

##Import template Log in to your zabbix web

Click Configuration->Templates->Import

Download template zbx_kafka_templates.xml and upload to zabbix Then add this template to Kafka and configure JMX interfaces on zabbix

Enter Kafka IP address and JMX port If you see jmx icon, you configured JMX monitoring good!

Troubles

if you have problems you can check JMX using this script #!/usr/bin/env bash

 ZBXGET="/usr/bin/zabbix_get"
 if [ $# != 5 ]
 then
 echo "Usage: $0 <JAVA_GATEWAY_HOST> <JAVA_GATEWAY_PORT> <JMX_SERVER> <JMX_PORT> <KEY>"
 exit;
 fi
 QUERY="{\"request\": \"java gateway jmx\",\"conn\": \"$3\",\"port\": $4,\"keys\": [\"$5\"]}"
 $ZBXGET -s $1 -p $2 -k "$QUERY"

eg.: ./zabb_get_java zabbix-java-gateway-ip 10052 server-test-ip 12345 'jmx[java.lang:type=Threading,PeakThreadCount]'

For monitoring kafka consumers you should install Burrow daemon and jq tools on kafka host
