Re: Is Django logging multi-process safe?

[Dan Davis]

Eric, thanks for confirming.  I've written my share of logrotate.d files,
but I may push to do something else, like send them directly to
Elasticsearch with a delay of some sort.

Re: Is Django logging multi-process safe?

[PASCUAL Eric]

Hi,


If you are running on a Linux system, you'd better using the standard stream 
logs and logrotate to manage file rotating.


The later is the blessed tool for this kind of task, since it manages for free 
the compression of rotated files and removal of oldest ones if you want to.


Regards


Eric

Looks like I should use a WatchedFileHandler and then have logrotate do the 
logging.   If the file pointer is moved by another process, then it will work.
Does gunicorn patch this for me?   Will I be better off using syslog or 
something?
