Description Surya Seetharaman 2021-08-10 17:18:27 UTC 
Description of problem:

We see lots of “WARN|Unreasonably long 13636ms poll interval” logs in the scaled up clusters [OCP-OVN-K]. This can be attributed to sbdb or controller or northd doing something that makes it busy and could thereby indicate load on the cluster.

It would be good if we could expose this somehow as a metric or alert and configure a decent threshold value based on the size of the cluster and document this to somehow indicate in an easier way if OVN is busy or not.

Its more of a feature/rfe than a bug. This was discussed briefly during the OVN-OVN-K sync up on August 10th.

This issue is being closed as an automatic process due to the issue's age. If you wish to re-open this issue, please do so in Jira (https://issues.redhat.com) in the 'FDP' project. Please be sure to set the component to the latest OVN version where this issue is known to occur. If this is a feature request or improvement, please set the component to 'OVN'.
Comment 2 Ilya Maximets 2024-02-15 14:06:04 UTC 
FWIW, the 'long_poll_interval' coverage counter was added in upcoming
openvswitch 3.3 release.  OVN 23.04 will have it as well since it will
use OVS 3.3 as a submodule.

If something more is needed, feel free to open a Jira issue.
