# This is a munin plugin to track the amount of disk space each node's
|
|
# StorageServer is consuming on behalf of other nodes. This is where the
|
|
# shares are kept. If there are N nodes present in the mesh, the total space
|
|
# consumed by the entire mesh will be about N times the space reported by
|
|
# this plugin.
|
|
|
|
# Copy this plugin into /etc/munun/plugins/tahoe-storagespace 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-storagespace]
|
|
# env.basedir_NODE1 /path/to/node1
|
|
# env.basedir_NODE2 /path/to/node2
|
|
# env.basedir_NODE3 /path/to/node3
|
|
#
|
|
# Allmydata-tahoe must be installed on the system where this plugin is used,
|
|
# since it imports a utility module from allmydata.utils .
