Statistics are not being collected for some nodes. Everything else seems to be working fine, but a for a few nodes stats are not being collected. </p> <p>2. When mininet exits, one or two nodes are left "dangling" in the oper space. Note that the inventory data (node connector, the node core data, etc.) are deleted, only statistics are left behind (most of the time just a partial set of table stats, e.g. 145 empty tables out of 254). Connecting/disconnecting mininet of the same size clears the condition. (i.e. where the dangling 'shadow' node is re-discovered, the old dangling stats are overwritten by a newly collected set of stats).</p> <p>Operating System: All<br/> Platform: All</p> CONTROLLER-895

Stats not being collected from all nodes, dangling nodes left in oper data store after mininet disconnects

For example:</p> <p>{<br/> -nodes: {<br/> -node: [<br/> -{<br/> id: "openflow:56"<br/> -node-connector: [<br/> -{<br/> id: "openflow:56:3"<br/> flow-node-inventory:port-number: "3"<br/> flow-node-inventory:supported: ""<br/> flow-node-inventory:advertised-features: ""<br/> flow-node-inventory:configuration: "PORT-DOWN"<br/> flow-node-inventory:current-feature: ""<br/> flow-node-inventory:current-speed: 0<br/> flow-node-inventory:maximum-speed: 0<br/> flow-node-inventory:hardware-address: "DA:6E:F5:DE:3E:C9"<br/> flow-node-inventory:peer-features: ""<br/> flow-node-inventory:name: "s56-eth3"<br/> -flow-node-inventory:state: {<br/> live: false<br/> blocked: false<br/> link-down: true<br/> }<br/> }<br/> ]<br/> }<br/> ]<br/> }<br/> }</p> <p>The second half of this bug (lingering nodes in operational store) is effectively a duplicate of 2089 and 2091.</p> <p>The first half (stats not being collected) could still be occurring, but it would be good if Jan could confirm that it is and, if it's, not close the bug.</p> <p>I hope this bug is solved by <br/> <a href="https://git.opendaylight.org/gerrit/#/c/11664/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/11664/</a></p> <p>This bug is part of the project to Move all ADSAL associated component bugs to ADSAL.</p> Development External issue ID 2078 External issue URL Rank 0|i02n7z:
