#. What this is: Functions for testing with Prometheus and Grafana. Sets up
#. Prometheus and Grafana on a master node (e.g. for kubernetes, docker,
#. rancher, openstack) and agent nodes (where applications run).
#. Prerequisites:
#. - Ubuntu server for master and agent nodes
#. - Docker installed
#. Usage:
#. $ git clone https://gerrit.opnfv.org/gerrit/models ~/models
#. $ cd ~/models/tools/prometheus
#. $ bash prometheus-tools.sh setup
#. $ bash prometheus-tools.sh clean
#
