Summary
------------
The Barometer@OPNFV project adds a platform telemetry agent to compute nodes
that is capable of retrieving platform statistics and events, and relay them
to Openstack Gnocchi and Aodh. The telemetry agent currently supported by barometer
is collectd. Some additional collectd plugins and application were developed to add
the following functionality:

Write/publishing Plugins:

- aodh plugin: A notification plugin that pushes events to Aodh, and
  creates/updates alarms appropriately.
- SNMP agent plugin: A write plugin that will act as an AgentX subagent that
  receives and handles queries from SNMP master agent and returns the data
  collected by read plugins. The SNMP Agent plugin handles requests only for OIDs
  specified in configuration file. To handle SNMP queries the plugin gets data
  from collectd and translates requested values from collectd’s internal format
  to SNMP format. Supports SNMP: get, getnext and walk requests.
- gnocchi plugin: A write plugin that pushes the retrieved stats to Gnocchi.
  It’s capable of pushing any stats read through collectd to Gnocchi, not just
  the DPDK stats.

Read Plugins:

- Intel RDT plugin: A read plugin that provides the last level cache
  utilization and memory bandwidth utilization.
- virt plugin: A read plugin that uses virtualization API libvirt to gather
  statistics and events about virtualized guests on a system directly from the
  hypervisor, without a need to install collectd instance on the guest.
- Open vSwitch stats plugin: A read plugin that retrieves interface stats from
  OVS.

In addition to the previous plugins from the Danube Release described below.
