Description

Problem

API to get LLB data for displaying the graphs

Solution

Have added new API "https://192.168.85.47:8888/llb/graph_data"
to fetch the values of llb for displaying graphs.
Here have added logic to get data based on from_time, to_time, time_interval and link_name

Testing Done

"https://192.168.85.47:8888/llb/graph_data"

is returning records as per the time interval

Request:

{
"query": {
"from_time": "now-15m",
"to_time": "now",
"link_name": "VLAN-162"
}
}

Response:
