# This is a munin plugin which pulls data from the server in
# misc/operations_helpers/spacetime/diskwatcher.tac . It produces a graph of how much space is
# present on all disks across the grid, and how much space is actually being
# used. The plugin should be configured with env_url= pointing at the
# diskwatcher.tac webport.
