RapidMiner Server maintains three types of logs that track activity. You can refer to these logs if the platform, a process or a job agent encounters an error:
- RapidMiner Server logs record activity related to platform operations. This includes startup processes, changes to settings, database accesses, etc. Any operations error is written to the RapidMiner Server log file.
- Process execution logs record the status of process execution.
- Job Agent logs record the status of Job Agents.
