Barometer Configuration Guide

This document provides guidelines on how to install and configure Barometer with Apex and Compass4nfv. The deployment script installs and enables a series of collectd plugins on the compute node(s), which collect and dispatch specific metrics and events from the platform.

Pre-configuration activities - Apex

Deploying the Barometer components in Apex is done through the deploy-opnfv command by selecting a scenario-file which contains the barometer: true option. These files are located on the Jump Host in the /etc/opnfv-apex/ folder. Two scenarios are pre-defined to include Barometer, and they are: os-nosdn-bar-ha.yaml and os-nosdn-bar-noha.yaml.

$ cd /etc/opnfv-apex
$ opnfv-deploy -d os-nosdn-bar-ha.yaml -n network_settings.yaml -i inventory.yaml –- debug

Pre-configuration activities - Compass4nfv

Deploying the Barometer components in Compass4nfv is done by running the deploy.sh script after exporting a scenario-file which contains the barometer: true option. Two scenarios are pre-defined to include Barometer, and they are: os-nosdn-bar-ha.yaml and os-nosdn-bar-noha.yaml. For more information, please refer to these useful links: https://github.com/opnfv/compass4nfv https://wiki.opnfv.org/display/compass4nfv/Compass+101 https://wiki.opnfv.org/display/compass4nfv/Containerized+Compass

The quickest way to deploy using Compass4nfv is given below.

$ export SCENARIO=os-nosdn-bar-ha.yml
$ curl https://raw.githubusercontent.com/opnfv/compass4nfv/master/quickstart.sh | bash

Hardware configuration

There’s no specific Hardware configuration required. However, the intel_rdt plugin works only on platforms with Intel CPUs.

Feature configuration

All Barometer plugins are automatically deployed on all compute nodes. There is no option to selectively install only a subset of plugins. Any custom disabling or configuration must be done directly on the compute node(s) after the deployment is completed.

Upgrading the plugins

The Barometer components are built-in in the ISO image, and respectively the RPM/Debian packages. There is no simple way to update only the Barometer plugins in an existing deployment.
