Dynamic file name doesn't work in rsyslog

The filename in rsyslog can be either static or dynamic. The later is useful if you would automatically split messages into different files based on some message criteria. I need split logs depend on IP -like: 10.10.10.10.log Why doesn't it work? Can I use something different to create it? Maybe python/bash script?

My config file look like this: [rsyslog v5]
