Barometer Release Notes
This document provides the release notes for Euphrates release of Barometer.
Important notes
None to date.
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.

Features to Date
Release B
The features implemented for OPNFV release B (as part of SFQM) in DPDK include:
- Callback API to enable TX/RX timestamping to measure latency through DPDK.
- Extended NIC statistics API for 1GB, 10GB and 40GB NICs to expose detailed
statistics for DPDK interfaces in addition to the overall aggregate statistics.
- DPDK Keep Alive.
Release C
The features implemented for OPNFV release C (as part of SFQM) include:
- DPDK extended NIC stats API improvement; migrate from key value pairs to
using id value pairs.
- DPDK Keep Alive improvement, so that core status is exposed through a posix
shared memory object.
- collectd dpdkstat plugin that can retrieve DPDK interface statistics.
- collectd ceilometer plugin that can publish any statistics collected by
collectd to ceilometer.
- Fuel plugin support for the collectd ceilometer plugin for OPNFV.
Release D
The features implemented for OPNFV release D include:
- collectd hugepages plugin that can retrieves the number of available and free hugepages
on a platform as well as what is available in terms of hugepages per socket.
- collectd Open vSwitch Events plugin that can retrieves events from OVS.
- collectd mcelog plugin that can use mcelog client protocol to check for memory Machine
Check Exceptions and sends the stats for reported exceptions.
- collectd ceilometer plugin that can publish any statistics collected by
collectd to ceilometer.
