Meeting minutes:


Notes from last meeting:

Demo from Barometer:

-       Possibly create a demo and record it?

-       Demo around containers/VM with metrics

-       Float around few ideas, get comments over next calls

-       Find a new way to use Barometer, would be good

-       Demo ideas:

  • Barometer for system tests/debugging.
    • Look at network interfaces, OVS stats, etc., to track whats happening in an openstack deployment
  • Need to know if there are any openstack deployments already available in opnfv pods
  • Have a real time demo to show graphana dashboards in opnfv pods 

Agenda:

  1. Status of Release
    1. What do we want in the release?


    2. virt plugin enhancements

      Virt plugin should be enhanced to provide the following additional details:

      		Release GXX

      Image AddedBAROMETER-99 - Virt plugin enhancement -- VM names OPEN

      ovs-dpdk-statsThe ovs-dpdk-stats plugin should include extended dpdk stats per interfaceRelease GXX

      Image AddedBAROMETER-96 - Enable OVS-DPDK PMD Statistics OPEN

      ovs-dpdk-events link statusThe ovs-dpdk-events plugin should indicate link status change eventsRelease GXX

      Image AddedBAROMETER-109 - ovs-events link status OPEN

      DMA Functionality

      The DMA Local Agent will provide the following features:

      • Local processing of metrics – Allows metrics to be sampled at a higher rate than storage rate for detection of short-lived conditions.
      • Runtime configuration of collectd – Collectd configuration can be managed remotely with the Local Agent providing the writing of collectd configuration and collectd restart.
      • Simple OpenStack metadata discovery – Provide runtime information related to the mapping between virtual and physical elements.  The metadata can be attached to metric sent by collectd.
      		Release GXX

      Image AddedBAROMETER-95 - The DMA project will provide additional functional for the Barometer project OPEN

      DMA ContainerAdd DMA container buildRelease GXX

      Image AddedBAROMETER-94 - The DMA project will exist as a container separate from the collectd container OPEN

      Collectd ovs_stats plugin does not collect dpdk interface statistics if under bond interface

      The ovs stats plugin collects the right set of data in case the dpdk interfaces are mapped directly under the ovs bridge. But for the use case where a bonding interface is needed underneath the ovs bridge, ovs stats cannot pull the dpdk interface statistics.

       

      		Release GXX


      Image AddedBAROMETER-92 - Collectd ovs_stats plugin does not collect dpdk interface statistics if under bond interface OPEN


    3. Original plan stalled by no release from Collectd.  
    4. virt plugin enhancements – Complete waiting on release
    5. ovs-dpdk-stats – 
    6. DMA Functionality - In progress
    7. DMA Container - In progress
    8. Collectd ovs_stats plugin does not collect dpdk interface statistics if under bond interface – completed waiting on release

  2. Participation in https://openmetrics.io/

Updates from last week:

-       Changed the Kolla container to include almost all Collectd plugins, taken from latest stable branch

  • Plugins are still taken from RPM build, relying on release version of Collectd
  • Not included plugins would gaming plugins, etc.
  • This is a great progress

-       No new updates about community release of Collectd

  • Intel team will prioritize backporting once Ansible script work is done

-       Collectd code reviews:

  • Lot of PRs, will take some time
  • The DPDK patch got merged, need to backport to 5.8
  • Sunku will ask the patch author to backport

-       Ansible scripts work:

  • Testing/validation on Ubuntu 16.04, 18.04 & Centos 7.5
  • Centos 7.3 had docker issues, related to docker missing packages
  • Latest docker Images is based on 7.5.3
  • Centos 7.5 images (qcow2) have different naming scheme, very similar to Ubuntu 18.04
  • There shouldn’t be any regressions, upgrading from 7.3 to 7.5.
  • We can look in to if we need to on 7.3
  • Require your help to review as patches are upstreamed

-       Milestone 8 – Oct 30th

  • Its not being pushed back

-       Review help:

  • Have 4 to 5 reviews pending in Barometer gerrit
  • Require reviews
  • Prometheus and Barometer
    • Should Barometer participate in the standardization effort under way in Prometheus.  (Yes!)
          • Driven by Prometheus for data format
          • Mentioned at Fosdem & Prometheus conference
          • Standard is named as open metrics, submitted to IEEE
          • Gone quite far, need 3 implementations of metrics format for this standard
          • Google is doing one implementation, 2nd one by Prometheus community
          • Trying to standardize data exchange format
          • While Prometheus only supports metrics, standards also supports logs.
          • Value of all this info is the correlation part
          • Matthias would send more info.
          • Need to make sure it wont impact our implementations of metrics in hardware/infrastructure level
          • The community is not generally attuned to lower layers.
    • Bring Barometer’s experience in monitoring the infrastructure.
    • End result could be too PaaSy ;)

-        Collectd container split: Need to check whether the separate container build jobs (master and stable) are configured correctly; so we can start adding config and build support for newer features (Emma/Kamil)
