You can Alter the default java wrapper settings on an agent by creating in the (Nolio agent install Directory)\conf a file named "custom.wrapper.conf".
In this file you can alter any new setting found in wrapper.conf and this setting will take presidence over any setting in wrapper.conf.
Example: To change the default log file count from the default of 5
Add to custom.wrapper.conf
wrapper.logfile.maxfiles=10
* Do not change the original wrapper.conf any changes to it will be overwitten during future upgrades*
If you have any Issues getting the Java Wrapper to except the new values make sure that the last line in wrapper.conf is
#include ../conf/custom.wrapper.conf
