/services-logs/prelude/vco-app/file-logs does not changeAria Automation Orchestrator 8.x
The configured log rotation set in System Settings > Log configuration applies to logs for the Orchestrator client which are stored in /data/vco/usr/lib/vco/app-server/logs/.
Logs within folder /services-logs/prelude/vco-app/file-logs are rotated by the Appliance configured log rotation and therefor may be retained for a longer period.
