#. What this is: Cleanup script for the VES monitoring framework.
#. With this script a VES deployment can be cleaned from one or more hosts.
#.
#. Prerequisites:
#. - VES framework deployed as in ves-setup.sh in this repo
#.
#. Usage:
#. bash ~/ves/ves-setup.sh clean <what> [cloudify]
#. what: one of all|influxdb|grafana|collector|kafka|collectd|agent|nodes
#. barometer: clean barometer
#. agent: clean VES agent
#. kafka: clean kafka
#. zookeeper: clean zookeeper
#. grafana: clean grafana
#. influxdb: clean influxdb
#. collector: clean VES collector
#. nodes: clean VES code etc at nodes
#. cloudify: (optional) clean up cloudify-based deployments
#.
#. See demo_deploy.sh in this repo for a recommended sequence of the above.
#.
#. Status: this is a work in progress, under test.
# http://docs.opnfv.org/en/latest/submodules/barometer/docs/release/userguide/collectd.ves.userguide.html
