In 641858783778ee14b627a55df48f81ad40c94555 we removed the extra vars from several roles. Well it's actually important in just one, and only sometimes. Anyways if and only if the dns server gets set incorrectly on nodes (happens when the lab is having trouble) collectd adds a DNS server, 8.8.8.8 by default which means we go from "it might work eventually" to "guaranteed to never work" once CollectD runs without the dns_server var changed from default. This went unnoticed because days can pass between issues like this. Anyways alls the builds are failing now on it, so need to readd it at least here.

Shaker Data Plane Performance Dashboards
Two dashboards have been provided with Browbeat for Shaker.
Browbeat Shaker Scenarios with Throughput vs Concurrency -------------------------------------------------------This Shaker dashboard aims to present data plane performance of OpenStack VMs connected in different network topologies in a summarized form. Three distinct visulizations representing L2, L3 E-W and L3 N-S topologies along with the corrensponding markdown to exaplain each visualization make the "Browbeat Shaker Scenarios with Throughput vs Concurrency" dashboard. For each network topology, average throughput for TCP download and upload in Mbps is expressed vs the VM conccurency (number of pairs of VMs firing traffic at any given moment). For example, in the L2 scenario if the average throughput is 4000 Mbps at a concurrency of 2, it means that each pair of VMs involved average at 4000 Mbps for the duration of the test, bringing the total throughput to 8000 Mbps(avg throughput*concurrency).
Browbeat Shaker Cloud Performance Comparison
This Shaker dashboard lets you compare network performance results
from various clouds. This dashboard is ideal if you want to compare data
plane performance with different neutron configurations in different
clouds. For each topology, a visualization comparing
tcp_download
and tcp_upload
per cloud name and
a visualization comparing ping latency per cloud name is generated in
the dashboard along with instructions in markdown for advanced filtering
and querying.
Note
You can filter based on browbeat_uuid
and
shaker_uuid
to view results from a specific run or shaker
scenario only and record.concurrency
and
record.accommodation
to filter based on the subest of the
test results you want to view.
