Observe meter stats requests are not being sent to switch.<br/> 4) If we push a meter, this gets correctly installed in switch but no stats get reported because of the above.</p> <p>Workaround:</p> <p>Disconnect and connect the switch, now the meter stats messages are being sent.</p> <p>BR/Luis</p> <p>Operating System: All<br/> Platform: All</p> OPNFLWPLUG-624

He plugin: Meter stats not reported the first time switch connects to controller

Bug Resolved Done Anil Vishnoi Luis Gomez Mon, 22 Feb 2016 20:53:45 +0000 Mon, 27 Sep 2021 09:01:43 +0000 Tue, 8 Mar 2016 07:16:23 +0000 General 0 1 <p>stable/beryllium : <a href="https://git.opendaylight.org/gerrit/35904" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/35904</a></p> <p>Root cause of this issue is a race condition that pops up because of the clustering introduction in openflowplugin HE design. Statistics manager sends the group/meter feature request and once it receives the response from the switch it checks if the respective node is present in operational data store or not. If node is present it writes the group/meter feature in the Oper data store and also update the stats capability with meter_stats. But if the node is not present it just ignores the write to data store. This scenario can occur, if the group/meter response comes before the inventory manager write node description to data store.</p> <p>To fix this issue, this patch see sends the group/meter feature request again in regular polling cycle if switch node is not present in the operational data store.</p> <p>master branch :<a href="https://git.opendaylight.org/gerrit/#/c/35905/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/35905/</a></p> Development External issue ID 5404 External issue URL Rank 0|i032av:
