QoS Manager
This program implements methods provided by the qos object on U-Bus. This is done by calling libqos provided by easy-soc-libs.
UCI Config
qosmngr requires a configuration file provide objects over ubus. The configuration file is an uci file /etc/config/qos. Sample configuration file is provided below.

uBus API
ubusd has to be running all time, as it exposes the qos functionality over ubus. By default,qosmngr registers below namespace with ubus.
root@iopsys:~# ubus -v list | grep qos
'qos' @e1f3b458
root@iopsys:~# root@iopsys:~# ubus -v list qos
'qos' @e1f3b458

queue_stats : {"ifname":"String","qid":"Integer"}-
ifname: interface name for which we want to get the QoS statistics. Optional argument: if not provided, the statistics of all ports for all queues are returned. -
qid: the TX queue ID for which we want to get the statistics. Optional argument: if not provided, the statistics of all queues for a given interface are returned.
The response given by this method is a JSON-formatted dump as such:
