-# This is a munin plugin to track the average number of shares per file in
-# each node's StorageServer. If this number is 100, that suggests there is
-# only a single node in the entire mesh. If the number is 2, that suggests
-# that there are 50 nodes in the entire mesh. If the number is 1, that
-# suggests that there are >= 100 nodes in the entire mesh. (if there were a
-# million nodes, this one node would only see a single share per file, so the
-# number of shares-per-file will never be less than 1).
-
-# Copy this plugin into /etc/munun/plugins/tahoe-sharesperfile and then put
-# the following in your /etc/munin/plugin-conf.d/foo file to let it know
-# where to find the basedirectory for each node:
-#
-#  [tahoe-sharesperfile]
-#  env.basedir_NODE1 /path/to/node1
-#  env.basedir_NODE2 /path/to/node2
-#  env.basedir_NODE3 /path/to/node3
