JVM (Jolokia)¶

Configuration¶

Description: Enable the jvm collector, and collect jvm Metrics information through the jvm collector.

Application Integration with Jolokia¶

The DataKit installation directory already provides the Jolokia agent. It is located in the datakit/data/ directory, providing two types of agent libraries: jolokia-jvm-agent.jar and jolokia-war.war.

The following examples are all based on the jar execution method.

• Start configuration for javaagent

java -javaagent:C:/'Program Files'/datakit/data/jolokia-jvm-agent.jar=port=8089,host=localhost -jar your_app.jar

Enable DataKit Collector¶

• Enable the collector

The collector is located in the datakit/conf.d/jvm directory. After entering the directory, copy jvm.conf.sample and rename the new file to jvm.conf. Mainly configure url, other parameters can be adjusted as needed.

urls = ["http://localhost:8089/jolokia"]

The above configuration will generate Measurement sets starting with java_.

• Restart DataKit
