Description Vishal Thapar 2018-07-10 15:47:37 UTC

Description of problem:

Openflow Plugin in OpenDaylight has stats-polling enabled by default. This results in ODL nodes polling all OVS devices to get stats for flows, groups, ports etc. This adds a significant overhead with no value add as none of the services in OpenDaylight today use it. This should be disabled by default to help improve scale and performance.

Version-Release number of selected component (if applicable):
OSP13 + Oxygen


How reproducible:
Always as it is default configuration

Steps to Reproduce:
N.A.

Actual results:
N.A.

Expected results:
N.A.
