Hello,
I am trying to read flow statistics from a java opendaylight application
(run's as a karaf feature). I would appreciate some guidance on how to read
the flow statistics. I tried to install the opeflowplugin-services feature
as follows.
<dependency>
<groupId>org.opendaylight.openflowplugin</groupId>
<artifactId>odl-openflowplugin-flow-services</artifactId>
<type>xml</type>
<version>0.5.1</version>
<classifier>features</classifier>
</dependency>
My feature loads and runs.
However the method
.getAggregateFlowStatisticsFromFlowTableForGivenMatch(flowStatsInputBuilder.build())
.get().getResult();
Throws an exception :
Error getting flow stats
java.util.concurrent.ExecutionException:
org.opendaylight.controller.md.sal.dom.api.DOMRpcImplementationNotAvailableException:
No implementation of RPC
AbsoluteSchemaPath{path=[(urn:opendaylight:flow:statistics?revision=2013-08-19)get-aggregate-flow-statistics-from-flow-table-for-given-match]}

I am also seeing a lot of these exceptions :

I am stuck. Any help would be appreciated. Thank you.
