Cgminer: log screen out to file

[leetrung74]

I want to log screen out to file but can not
My command is: Cgminer --scrypt-jane -o stratum+tcp://ultra.nitro.org:3337 -u xxx -p xxx -I 12 -g 2 -w 256 --lookup-gap 4 --gpu-engine 1000 --thread-concurrency 36864 --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600 > c:\gpu.txt

Does any body know about command monitor|-m <arg> in cgminer?
Please show me some examples

Thanks
