Metrics.csv

[Adwi11]

I have been running scope sole just to test, but there is no produced metrics.csv file at runtime. Do I need to run it which some testbed in order to create that metrics file ?

No but you need to have users exchanging some type of traffic with the base station.

Can I simulate that using scope alone? I don't see the param which enables that exchange in the set of its configurations.

You would usually do that by running it on two different compute machines with software-defined radios connected to them. srsRAN should also let you use a simulation mode with zmq but I've never used it.

Hi, so actually just to clarify. I am trying to deploy an xApp onto the colosseum-near-rt-ric NearRT RIC and connect it to colosseum Scope without using colosseum. So, can I do that on my machine using two different VMs one for near rt ric and one for scope and then to produce the metrics.csv. Thanks a lot for answering.

You should be able to, provided that you set the IP addresses accordingly. About the metric generation, I've never used this in zmq mode but there is a debug mode to send fixed metrics from the BS to the xApp once the xApp subscribes to the BS. This might be helpful to verify connectivity. https://github.com/wineslab/colosseum-scope-e2/blob/6ba74250dec879458d35ee887d41b29e14fbb098/build_odu.sh#L6

Okay, so I think it's better to use colosseum itself to use scope and for xApp development. Could we discuss the use and access of colosseum for the same and exactly which containers I should use for getting the metrics and then using it in xApp.
