Resin¶

Installation Configuration{#config}¶

Explanation: The example Resin version is Windows environment Resin/4.0.66 (Windows).

Metric collection is achieved through the use of jolokia-jvm-agent to collect Resin runtime metrics.

Resin enables metric collection¶

Configure config/resin.properties

ADD jvm_args ，parameter description：

javaagent：jolokia-jvm-agent
port=9530 # jolokia-jvm-agent export port

jvm_args  : -Xmx2048m -XX:MaxPermSize=256m -javaagent:C:/"Program Files"/datakit/data/jolokia-jvm-agent.jar=port=9530

Restart Resin

Double-click resin.exe

DataKit Collector Configuration¶

Enables the DataKit JVM plugin and copy the 'sample' file

cd datakit/conf.d/jvm
cp jvm.conf.sample jvm.conf

Modify jvm.conf configuration file

Main parameter description
