I tried to modify the logback.xml file to add in the z-wave info output to another file (as the wiki on the z-wave binding advises), but it had no effect on my logs. I typed in the addition, when that did not work, I did a cut and paste to make sure I didn’t mistype anything and still no luck. When my log file got too large (null pointer errors from an items file), I tried to change the logback.xml again to do more frequent log rotation.
When I did this, all logging stopped. The last log is timestamped at 9:30 this morning (when I stopped openhab) to make the changes in the logback.xml. I restarted openhab and the only thing that is updating in the /var/log/openhab/ folder is the 2015_12_27.request.log.
Any help would be appreciated!

Edit:
PS: Using raspbian w/ openhab 1.7.1 on a Raspberry Pi 2, also, a reboot didn’t help.
Always make a backup of a config file when making edits so you can just copy the backup over your mangled copy.
It sounds like you may have had a syntax error in your file when you made your initial edit which got carried over for each subsequent edit until the logger was completely broken.
Here is my logback.xml file which shunts the zwave and nest logs to separate files, for reference.

Notice that it must be valid XML. Also notice the order of the elements. Appenders go first, then loggers. To get the log files separated you need to assigned your appenders to the given logger.
