Implementing DB2 Profiler Plugin

[snmsmanager]

I've created sample DB2 plugin by using existing MariaDB plugin and I've successfully compiled and generated plugin jar file. can you please explain the steps needed to Implement this Profiler Plugin? Is it sufficient to copy DB2 plugin jar file under agent/plugins?

[emeroad]

Yes, just copy the jar file.
If you place the jar in agent/plugins, it will be automatically loaded by ServiceLoader.

Don't forget the services config file as well.

DB2Plugin.java.txt
@emeroad thank for the instruction.

I’ve copied “pinpoint-db2-plugin-3.0.0-SNAPSHOT.jar” to agent’s plugin location and it is registered properly. Now I’m getting below error for addDriverTransformer method in **** file. I'm not able to see any connections related to DB2 in corelation map.
