INTCollector issues

Hello. i’m trying to use INTCollector( tunv_ebpf / INTCollector · GitLab) to collect INT data from a testbed. I’m really struggling to do so, first I couldn’t install ONOS properly, so I installed a VM from a tutorial( Basic ONOS Tutorial - ONOS - Wiki (onosproject.org)) to have a implementation of ONOS in my VM. After that I installed a P4 environment using the .sh script in the p4-guide Github repository. Now I’m just trying to run it and I’m failing to do so.

I’m receiving the following log when trying to run a pytest with InfluxDB:

I’m not sure if the problem is the configuration of InfluxDB, since i Had a problem with it last time I ran a test. Where can I see if it is connected to localhost(Both InfluxDB and INTCollector)?

Did anyone use INTCollector before? If there is any VM .ova that has a fully functioning INTCollector or any INT collector API, I would appreciate. Thanks

UDPATE: It seems the problem lies in the bcc package necessary for the application. I’m struggling to make it work. I’m using a Ubuntu 20.04.6 LTS with llvm 10.0.0(eventhought it says that my version is in /usr/lib/llvm-60/include 6.0.1). I’ve tried the latest release and now I tried the 0.24 release. It helped a little to build the package from source, however it’s still not working

I’ve managed to run the BCC, however I still not able to run INTCollector.

When i tried to start InfluxDB the following occurs:

bpf: Argument list too long. Program too large (1400 insns), at most 4096 insns
