# This plugin monitors number of workers, total memory used and average memory per process for uWSGI.
# Here are the symlinks to enable it

# ln -s /usr/share/munin/plugins/uwsgi_ /etc/munin/plugins/uwsgi_average
# ln -s /usr/share/munin/plugins/uwsgi_ /etc/munin/plugins/uwsgi_memory
# ln -s /usr/share/munin/plugins/uwsgi_ /etc/munin/plugins/uwsgi_processes
