To get access to the juju environment, please run the following from the place where you installed LDS:

# If you used the install-openstack tool, you want to do this first:
export JUJU_HOME=~/.cloud-install/juju
juju status

# Get an interactive shell with the right ENV sourced on the landscape
# server itself.
juju ssh landscape-server/0 sudo 'JUJU_HOME=/var/lib/landscape/juju-homes/`sudo ls -rt /var/lib/landscape/juju-homes/ | tail -1` sudo -u landscape -E bash'

# You should see a lot of openstack services with this command:
juju status

At this point, you can poke around, deploy services, and generally wreak havoc in your environment.

In other words, here is where you would deploy ceilometer.

Good Luck!
