Yet-Another-Ryu-Simple-Network-Monitor

YARSNM is a simple network monitor for Ryu focusing on mesuaring network performance. It's able to collect network statistics such as packet loss, bandwidth, latency, speed on each link then expose them to REST API.

Stat	Unit	Note
Packetloss	%
Delay	ms
Link usage	Mbit/s
Bandwidth	Mbit/s	Don't get bandwidth if you are using mininet. False Value

And other unprocessed stats like delta_port_stats and delta_flow_stats, port stats and flow stats

Usage - check out the wiki

To start the Monitor use:

ryu-manager --observe-link --ofp-tcp-listen-port=6633 --wsapi-port=8080 controller_rest.py

Start with simple_switch_13 and ofctl_rest.

ryu-manager --observe-link --ofp-tcp-listen-port=6633 --wsapi-port=8080 ryu.app.simple_switch_13 ryu.app.ofctl_rest controller_rest.py

Rest api are all in controller_rest.py, Update on every 3 secs.
