 * the `ja-netfilter` will output debugging information to the `console` by default
 * add environment variable `JANF_OUTPUT=value` and start to change output medium
 * or add system property `-Djanf.output=value` to change output medium
-* output medium value: [`NONE=0`, `CONSOLE=1`, `FILE=2`, `CONSOLE+FILE=3`]
+* output medium value: [`NONE=0`, `CONSOLE=1`, `FILE=2`, `CONSOLE+FILE=3`, `WITH_PID=4`]
+* eg: `console` + `file` + `pid file name` = 1 + 2 + 4 = 7, so the `-Djanf.output=7`
