I think ofctl_rest.py is what you are looking for.
Example of use is as follows.
1) Run ryu-manager with ofctl_rest app.
$ ryu-manager ./ryu/app/ofctl_rest.py --verbose
2) Next, execute the following commands to dump flows.(*)
$ curl -X POST -d '{
"cookie": 0x8,
"cookie_mask": 0xffffffffffffffff,
}' http://localhost:8080/stats/flow/1 | jq .
3) Then, results will be shown as follow.
{
"1": [
{
"match": {
"in_port": 2
},
"flags": 1,
"table_id": 0,
"duration_sec": 1,
"priority": 11111,
"actions": [
"OUTPUT:456"
],
"idle_timeout": 60,
"cookie": 8,
"packet_count": 0,
"hard_timeout": 60,
"byte_count": 0,
"length": 88,
"duration_nsec": 6.45e+08
}
]
}
(*) ryu.app.ofctl_rest provides REST APIs for retrieving the switch stats
and Updating the switch stats. For more information about ofctl_rest.py
is described following.
