All the output that comes from daemons, queue's and logs are outputted to this folder:
/home/ploi/.ploi
You can find the respectively logs by identifying them by the ID thats in the name of the file. For example you will be able to find these logs if you have any daemons, queue's or cronjobs setup:
- worker-{id}.log - Workers are daemons and queue's
- scheduled-{id}.log - Schedules are the cronjobs and their output
The ID will match the one in your panel so you will know which log file to monitor/check.
