This presentation outlines the Service Assurance Project that is currently in development. The SA project will showcase the Barometer container and
make the container(s) available.
Providing Sufficient Measurement Context with Results <Jan 30, 2018>
The Barometer Project considers ETSI GS NFV-TST 008 V2.4.1 (2018-01) to define some of the key metrics, and their required Measurement Context.
...
It now remains to conduct a Gap analysis on the relevant Barometer Metrics, to ensure the that Measurement Context is available with the collectd results.
There are three related JIRA Tickets for the Gaps:

DMA Project
- Distribute some monitoring and analysis capabilities to the edge
- Allow faster polling rates locally without creating a bottleneck for transfer of large amounts of data to a central site.
- Allows fast remediation of node-local events
- Project is looking for an upstream community
- Would Barometer be a good fit?
...
- Polling vs Event capture for the monitoring agent
- Platform independent monitor agent
- Network Interfaces
- Kernel events
- VM / Container monitoring
- Common bus for Events / Telemetry / Config
- Common Object model
- Agent configuration
- Performance
- <<50ms and other timing requirements
Decisions
Polling vs Event capture for the monitoring agent <Feb 07 2017>
The scope of polling being discussed is that of the monitoring agent itself (on the node that’s being observed). Collectd is configured to run at a particular interval by default every 10 seconds. the question is, do you leave the read plugins poll for stats and events every time the read interval fires?
...
Network (over)load should be taken into consideration as regards which model to use (push vs pull), you don't want to destabilize the network. push is more scalable overall and preferred for fault management.
Agent configuration <Feb 14 2017>
Should be able to dynamically:
