# This is a munin plugin to track the number of directory nodes that a vdrive
|
|
# server is maintaining on behalf of other nodes. If a mesh has only one
|
|
# vdrive server (or if clients are only bothering to use a single one), then
|
|
# this will be equal to the number of dirnodes in use in the entire mesh.

# Copy this plugin into /etc/munun/plugins/tahoe-dirnodes and then put
|
|
# the following in your /etc/munin/plugin-conf.d/foo file to let it know
|
|
# where to find the basedirectory for the vdrive server.
