and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this

summary: OpenStack Telemetry - Alarming service
description: |
Ceilometer aims to deliver a Single Point Of Contact for billing systems,
providing all the counters they need to establish customer billing, across
all current and future OpenStack components. The delivery of counters must be
traceable and auditable, the counters must be easily extensible to support new
projects, and agents doing data collections should be independent of the
overall system.
.
Aodh provides the Alarming service as part of OpenStack telemetry.
