I think no-one has tried to use those plugins for some time, and they aren't
tested by the Tahoe-LAFS test suite. They're definitely insufficiently documented.
So if you encounter problems with the instructions below, please post again and
we'll give them some more attention.

In the munin configuration file, usually /etc/munin/plugin-conf.d/tahoe-conf .
The configuration for each plugin should be in a section named for the plugin,
but with '_' replaced by '-', e.g.

[tahoe-disktotal]
env_url=http://HOST:PORT

There's an example for a different plugin at the top of
<https://tahoe-lafs.org/trac/tahoe-lafs/browser/trunk/misc/operations_helpers/munin/tahoe_server_operations_>,
and more examples in
<https://tahoe-lafs.org/trac/tahoe-lafs/browser/trunk/misc/operations_helpers/munin/tahoe-conf>.
