Key New Features

 * Support for partitioning metric collection load across horizontally scaled-out central agents
 * New method of partitioning alarm evaluation load using tooz coordination, as opposed to a hand-crafted protocol
 * Much improved SQLAlchemy storage performance & scalability, so that MySQL or PostgreSQL can be used as the metering store for PoCs or small deployments
 * Support for hardware-oriented monitoring of IPMI sensors via notifications from either Ironic or a new standalone agent
 * More flexible & efficient SNMP monitoring:
 * batching queries for multiple SNMP metrics into a single call to each daemon
 * dynamic discovery of nodes deployed by TripleO for SNMP polling
 * the ability to more easily extend the range of SNMP metrics that ceilometer gathers
 * the ability to derive new metrics from arithmetic transformations applied to multiple primary metrics
 * Option to split off the alarms persistence into a separate database
 * Option to use notifications instead of RPC for metering messages
 * Metering of Neutron networking services: LBaaS, FWaaS & VPNaaS
 * New XenAPI compute inspector
 * Support for persisting events via the MongoDB & Hbase storage drivers (previously limited to SQLAlchemy)
 * Support for per-device metering of instance disks
 * Use of ceilometer as a collector for os-profiler data
 * New Telemetry section of the Cloud Administrator Guide
