Coroot doesn't recognize coroot-node-agent

[veer-pradhan]

Hi All,

I am developing a POC for distributed tracing using coroot-node-agent. I am running the coroot ui and node-agent in docker containers:

sudo docker run -d --name coroot-node-agent -p 8081:8081 --privileged --pid host -v /sys/kernel/debug:/sys/kernel/debug:rw -v /sys/fs/cgroup:/host/sys/fs/cgroup:ro ghcr.io/coroot/coroot-node-agent --cgroupfs-root=/host/sys/fs/cgroup
sudo docker run -d --name coroot -p 8080:8080 ghcr.io/coroot/coroot

It does not recognize the coroot-node-agent is also being run. Any help would be appreciated!

It seems that Coroot is not detecting metrics from the node-agent.

1. Check the /metrics endpoint of the node-agent:

curl http://localhost:8081/metrics

2. Ensure that the Prometheus configuration includes the correct target for the node-agent. Look for the scrape_configs section in your Prometheus configuration file. Sample configuration:

scrape_configs:
  - job_name: 'coroot-node-agent'
    static_configs:
      - targets: ['localhost:8081']

3. Access the Prometheus Targets page (usually /targets) and check if the node-agent target appears as "UP."

You should fix the port mapping to -p 8081:80 since the agent listens on port 80 by default.

We have had similar problems. In our case localhost should be changed in the host-ip address in the target address.
