 Description   

I executed the following REST API, but failed to get up-to-date flow statistics.
http://127.0.0.1:8080/controller/nb/v2/vtn/default/vtns/vtn_1/flows/detail?update=true

The response body for the above request didn't contain statistics information.

I think the root cause of this issue is CONTROLLER-833.
Therefore, after the CONTROLLER-833 is fixed, I'm going to test this issue again.

I've tested this issue using the Helium release candidate, and found out that the bug has been not fixed yet.

http://nexus.opendaylight.org/content/groups/staging/org/opendaylight/integration/distribution-karaf/0.2.0-Helium/

I've observed that the statistics information in the output of the flow API are same between when update=true and update=false.
It meant that VTN Manager failed to get up-to-date flow statistics.

update=true
===========

curl --user "admin":"admin" -H "Accept: application/json" -H \
"Content-type: application/json" -X GET \
http://localhost:8080/controller/nb/v2/vtn/default/vtns/vtn1/flows/detail?update=true

The response message for the above request was as follows:

{
"dataflow": [
{
(sinp)
"statistics":

{ "bytes": 10444, "duration": 117626, "packets": 110 }

,
(snip)
}

update=false

CONTROLLER-900 which is the root cause of this issue has been fixed.
