Can't obtain sessions info from API

[sincar74]

I all,
this is my first post, and I want to thank you all for this amazing project

Subject of the issue
I'm trying to get session information from API /api/v3/session, what I'm expecting is the number of current viewers connected to each channel, bandwidth tx, ..., but I always receive from API an all zero result:

{
  "": {
    "active": {
      "list": [],
      "sessions": 0,
      "bandwidth_rx_mbit": 0,
      "bandwidth_tx_mbit": 0,
      "max_sessions": 0,
      "max_bandwidth_rx_mbit": 0,
      "max_bandwidth_tx_mbit": 0
    },
    "summary": {
      "remote": {},
      "local": {},
      "reference": {},
      "sessions": 0,
      "traffic_rx_mb": 0,
      "traffic_tx_mb": 0
    }
  }
}

I'm honest, I didn't understand the meaning of the "collectors" parameter

Environment

• Ubuntu 20.04.6 LTS
• Docker version 24.0.7, build afdd53b
• docker run --detach --rm --name core --privileged --volume /opt/core/config:/core/config --volume /opt/core/data:/core/data --publish 80:8080 --publish 443:8181 --publish 1935:1935 --publish 1936:1936 --publish 6000:6000/udp datarhei/restreamer:latest

Could you help me, please?

Thanks

Hi,
inspecting with developer tools on Restremer gui, I realize that "collectors" are parameters for which I want the session information.
With collectors=hls I can retrieve what I'm searching for.
To have the number of viewers then, I suppose that, I have to count the numbers of object that have the channels guid inside the reference property.

Yes, in the active.list you have count the objects that contain the channel ID in the reference in order to get the number of currently watching viewers.
