Handy mod_wsgi process names¶
One of the reasons I started experimenting with gunicorn instead of mod_wsgi
was that it would help me identify the sites when looking at cpu/memory usage
with top. With standard apache+mod_wsgi, you only get line upon line of
/usr/sbin/apache2 -k start with no indication of which site it actually
is.
Turns out mod_wsgi can do that just fine, too! I got a comment on my
gunicorn blogpost
from Diederik v/d Boor that told me about
mod_wsgi’s display-name option. It was right there in mod_wsgi’s
WSGIDaemonProcess documentation
but I completely overlooked it.
What I did was to add a display-name like this:
WSGIDaemonProcess mysite display-name=mysite_wsgi user=xyz group=xyz
In top you might have to press c to view the full commandline for
every top line. (Tip: press W to write the top config to disk to persist
the change).
See this picture. It shows a couple of not-yet converted wsgi sites with the
unhelpful /user/sbin/apache2 name and a couple with the sitename with
_wsgi in it.
