log_path and callback plugin

[fanvalt]

Hello,

I would like to log in a file the output of the display when running a playbook, this is set with the log_path variable in logs/ansible.log

But I would like the output to be dispatch in a logfile whose name would be the playbook_name.hostname.nupro

I have a plugin that log into such a file but I cannot log the display log, 

Example: the display of the ansible-playbook command, looged in the logfile set by the log_path variable, when running the test_failed.yml playbook:

The contents of the logfile  test_failed.yml_localhost_3101 created by the callback plugin:

2017-03-14.11:30:54: msg : failed

Is there an easy way to proceed to rename the ansible.log file during the run of the ansible-playbook command and not in a script ?

I tried to use the log_plays plugin without any success

Is it possible to set the logfilename in the default.py  file ? or should this be done in another callback plugin ?
