If you have not implemented [log rotation](log_maintenance.html), you should compress and archive the log files located in the following directories to another place on your file server:
* `${tomcat.home}/logs/*`
* `${tds.content.root.path}/thredds/logs/*`
* `${tds.content.root.path}/tdm/*.log`
Note:
You will need to stop the Tomcat servlet container while performing the maintenance aforementioned steps.
