Run Graphite behind uwsgi + nginx in a subpath/subdirectory/non-root path
View graphite.conf
# This is the config I used for nginx to proxy graphite via uwsgi to a non-root path.
# Graphite is a stubborn Django app that must reside at the DocumentRoot level
# and is not readily moved to a subpath.
# The following config allows you to reach the graphite composer at
# http://HOSTNAME/graphite. The graphite will redirect all URLs back at the top
# level, so the remaining locations handle those and pass them back to the
# uwsgi server.

Push slurm cpu and memory cluster utilization to a carbon (graphite) instance for graphing
# vim: set ts=4 sw=4 et
""" - A script that will get CPU and Memory utilization
for a SLURM cluster and submit it directly to carbon's
pickle listener port.
This script uses the Python SLURM bindings to get cluster utilization,
which accounts for nodes being allocated exclusively or totally allocated.
