How to configure memcached logging?

Question

memcached

Memcached installed and working (writing and reading values ​​via python).
I need to look at the logs, but:
1. There is no memcached.log file anywhere
2. I created a file and it is not filled
3. -vv option is registered in /etc/memcached.conf
4. I run it like this: sudo /etc/init.d/memcached start
5. Strange number one - if you do not run in darmon mode - then there is still no output to the console from memcached
Strange number two - if you connect by telnet - then at least write something - silence in response ...
ps aux | grep memcached
/usr/bin/memcached -vv -m 64 -p 11211 -u memcached -l 0.0.0.0 LOGFILE='/var/log/memcached.log'
