How to stream the last few lines of a file in Django?

Question

For monitoring purposes I'd like to stream the last N lines of a log file into a Django website interface. Like displaying the result of a tail -f filename command.

Basically I'd like to do the same as supervisord which alows to logtail a process from its http interface.

Any idea on how to do that?

Answer 1

As requested by the OP, here is an example using webtail:

$ webtail \
    --port=8000 \
    --files=/var/log/nginx/error.log,/var/log/nginx/access.log \
    --logging=warn

As I understand from the comments - the OP needs a solution that supports websockets. Webtails does. If you look in the webtail.py file:

routes = [(r'/', MainHandler), (r'/tail/', TailHandler),
    (r'/signin/', SigninHandler), (r'/signout/', SignoutHandler)]

where TailHandler is:

from tornado.websocket import WebSocketHandler

....

class TailHandler(WebSocketHandler):

I'm using this for monitoring lots of logs, and it works like a charm :)
