Kafka is a distributed, partitioned, replicated commit log service. For more information visit kafka.apache.org.
Even if the Kafka plugin is not configured, Stackdriver Monitoring discovers Kafka services running in your Google Cloud project by:
- Searching instance names for kafka
- Checking for ports opened to 9092 via firewall rules
The services discovered are displayed on the Kafka Services page in the Resources menu. After you install the Monitoring agent and configure the Kafka plugin on your instances, Monitoring populates the Kafka Services page with inventory and metrics.
Configuring Monitoring to monitor Kafka
After you install the Monitoring agent, use the following instructions to configure the Kafka plugin on your instances.
The Kafka plugin requires version 5.5.0-257 or later of the Monitoring agent. To update the agent, see Upgrading the agent.
Enabling the Kafka monitoring plugin
Kafka is monitored via JMX. Monitoring supports monitoring Kafka version 0.8.2 and higher.
(cd /opt/stackdriver/collectd/etc/collectd.d/ && sudo curl -O https://raw.githubusercontent.com/Stackdriver/stackdriver-agent-service-configs/master/etc/collectd.d/kafka-082.conf)
The downloaded plugin configuration file assumes that your Kafka server is configured to accept JMX connections on port 9999. If you have configured Kafka with a different JMX port, as root, edit the file and follow the instructions to change the JMX port settings.
After adding the configuration file, restart the Monitoring agent by running the following command:
sudo service stackdriver-agent restart

GenericJMX plugin used to monitor
Kafka, see Plugin:GenericJMX.
