Hi Stefan,
I hope you wanted to monitor SOI using APM. You can do that using standalone java agent and EP agent.
Since SOI application runs as windows service(SAM application server, Event Integration, SAM integration services), you need to unpack standard java agent files and add java agent configurations to SOI startup services/config files.
Also use EP agent to monitor logs, CPU, disk and memory of SOI application service.
Thanks,
Karthik
