# This playbook purges the Ceph MGR Dashboard and Monitoring
# (alertmanager/prometheus/grafana/node-exporter) stack.
# It removes: packages, configuration files and ALL THE DATA
#
# Use it like this:
# ansible-playbook purge-dashboard.yml
# Prompts for confirmation to purge, defaults to no and
# doesn't purge anything. yes purges the dashboard and
# monitoring stack.
#
# ansible-playbook -e ireallymeanit=yes|no purge-dashboard.yml
# Overrides the prompt using -e option. Can be used in
# automation scripts to avoid interactive prompt.
