# Logging

Ore Processor has a built-in JSON logging system. Logging helps server admins to trace and analyze player behaviour such as detecting dupe, errors, etc

Currently, the plugin will track:

* Commands: add upgrade, set upgrade, add items, subtract items, store hand/all, etc
* GUI: quick-sell, store, take, quick-craft, upgrade

Maximum size per log file is 1MB. Currently, the plugin **does&#x20;**<mark style="color:red;">**not**</mark>**&#x20;automatically remove old logs**, so you have to keep track of this by yourself. It is recommended to retain log files in the last 1 month.
