Confluent Kafka Monitoring with Zabbix

Zabbix Server

Enable Zabbix JMX Gateway

  1. Install zabbix-java-gataway

    yum install -y zabbix-java-gataway

  2. Configuring zabbix-java-gataway

    vi /etc/zabbix/zabbix_java_gateway.conf

    set START_POLLERS=10

  3. Configuring zabbix-server

    vi /etc/zabbix/zabbix_server.conf

    set to StartJavaPollers=5 Change IP for JavaGateway=IP_address_java_gateway

  4. restart zabbix-server and zabbix-java-gataway

    systemctl restart zabbix-server
systemctl start zabbix-java-gataway
systemctl enable zabbix-java-gataway

Install scripts for discovery JMX at Zabbix Server

# cd /tmp/
# git clone https://github.com/peepeepopapapeepeepo/zabbix-kafka-monitoring.git
# cd zabbix-kafka-monitoring/zabbix-server/
# cp jmx_discovery /etc/zabbix/externalscripts
# cp JMXDiscovery-0.0.1.jar /etc/zabbix/externalscripts
# chmod +x /etc/zabbix/externalscripts/jmx_discovery
# chmod +x /etc/zabbix/externalscripts/JMXDiscovery-0.0.1.jar

Kafka Each Servers

Enable JMX Kafka Server

  1. Create authentication files

    # cd /etc/kafka/
# _Username='kafka'
# _Password='k@fKaZaB'
# echo -e "${_Username}\t${_Password}" >> jmxremote.password
# echo -e "${_Username}\treadonly" >> jmxremote.access
# chown cp-kafka.confluent jmxremote.*
# chmod 600 jmxremote.*

  2. Edit systemd startup file

    # systemctl edit confluent-kafka
     | [Service]
     |                  :                       :
    +| Environment="KAFKA_JMX_OPTS=-Dcom.sun.management.jmxremote=true \
    +| -Dcom.sun.management.jmxremote.ssl=false \
    +| -Djava.net.preferIPv4Stack=true \
    +| -Dcom.sun.management.jmxremote.local.only=false \
    +| -Dcom.sun.management.jmxremote.port=12345 \
    +| -Dcom.sun.management.jmxremote.rmi.port=12345 \
    +| -Djava.rmi.server.hostname=<HostIP> \
    +| -Dcom.sun.management.jmxremote.password.file=/etc/kafka/jmxremote.password \
    +| -Dcom.sun.management.jmxremote.access.file=/etc/kafka/jmxremote.access"
# systemctl restart confluent-kafka

  3. Test JMX

    # mkdir /root/jmxterm && cd /root/jmxterm
# curl -sLO https://github.com/jiaqi/jmxterm/releases/download/v1.0.1/jmxterm-1.0.1-uber.jar
# java -jar jmxterm-1.0.1-uber.jar -l 127.0.0.1:12345 -u kafka -p k@fKaZaB
$> beans
$> info -b java.lang:type=Threading
$> get -b kafka.server:name=PartitionCount,type=ReplicaManager Value
$> get -b java.lang:type=Threading TotalStartedThreadCount
$> exit
# mkdir /root/jmxdump && cd /root/jmxdump
# curl -sLO https://github.com/r4um/jmx-dump/releases/download/0.9.3/jmx-dump-0.9.3-standalone.jar
# java -jar jmx-dump-0.9.3-standalone.jar -h 127.0.0.1 -p 12345 -c kafka:k@fKaZaB --dump-all

  4. Allow firewalld

    # firewall-cmd --permanent --new-ipset=jmx-zabbix --type=hash:ip
# firewall-cmd --reload
# firewall-cmd --permanent --ipset=jmx-zabbix --add-entry=<IP_address_java_gateway>
# firewall-cmd --reload
# firewall-cmd --permanent --new-service=jmx-zabbix
# firewall-cmd --permanent --service=jmx-zabbix --set-description="JMX for Zabbix JMX Gateway"
# firewall-cmd --permanent --service=jmx-zabbix --set-short="JMX for Zabbix"
# firewall-cmd --permanent --service=jmx-zabbix --add-port=12345/tcp
# firewall-cmd --reload
# firewall-cmd --permanent --new-zone jmx-zabbix
# firewall-cmd --reload
# firewall-cmd --permanent --zone=jmx-zabbix --add-source=ipset:jmx-zabbix
# firewall-cmd --permanent --zone=jmx-zabbix --add-service=jmx-zabbix
# firewall-cmd --reload
# firewall-cmd --info-ipset=jmx-zabbix
# firewall-cmd --zone=jmx-zabbix --list-all
# firewall-cmd --info-service=jmx-zabbix

  4. Install startup script and start Burrow as linux service

    # cd /tmp/
# git clone https://github.com/peepeepopapapeepeepo/zabbix-kafka-monitoring.git
# cd zabbix-kafka-monitoring/kafka-consumer/
# cp burrow.service /etc/systemd/service/
# systemctl daemon-reload
# systemctl start burrow.service
# systemctl enable burrow.service

  5. Functional Test

    # curl --noproxy "*" -s http://127.0.0.1:8000/v3/kafka/local/consumer | jq

Configure Zabbix Agent

  1. Install kafka_consumers.sh

    # mkdir /var/lib/zabbix/
# cd /tmp/zabbix-kafka-monitoring/kafka-consumer/
# cp kafka_consumers.sh /var/lib/zabbix/
# chmod +x /var/lib/zabbix/kafka_consumers.sh
# chown -R zabbix.zabbix /var/lib/zabbix/

  2. Install zabbix-agent configuration

    # cp userparameter_kafkaconsumer.conf /etc/zabbix/zabbix_agentd.d
# systemctl restart zabbix-agent

Zabbix Web GUI

Import template and value mapping file

  1. Import template (zbx_kafka_templates.xml, zbx_templates_kafkaconsumers.xml)

    Configuration > Templates > Import > Choose Files > Import

  2. Import value mapping (zbx_valuemaps_kafkaconsumers.xml)

    Administration > General > Drop Down List: Value Mapping > Import > Choose Files > Import

Note: Don't forget to set macro {$JMX_PASS} and {$JMX_USER}
