Hi, I configured signoz on k8s using the helm chart, now I want to instrument multiple tomcat application which are running outside of that cluster and they are running on a VM. I did install the java agent to collect open telemetry traces, stuck here what should be the signoz backend "OTEL_EXPORTER_OTLP_ENDPOINT=http://<IP of SigNoz Backend>:4317" ? I tried exposing the service for otel-collector pod, port: 4317, but that is not working for me. Any suggestions here ?

Hey, Can you show the created service for your

signoz collector

? AFAIK, by default it is configured as

ClusterIP

(see charts) In your case, you're trying to access the collector out of the same Kubernetes Cluster. I'd suggest configuring the collector service as either

loadBalancer

or

nodePort

, if you're sending huge data, I'd recommend configuring as

loadBalancer

See https://kubernetes.io/docs/concepts/services-networking/service/#loadbalancer on how to configure your service.

@Shivanshu Raj Shrivastava Its of type nodePort

# OtelCollector service
  service:
    # -- Annotations to use by service associated to OtelCollector
    annotations: {}
    # -- Service Type: LoadBalancer (allows external access) or NodePort (more secure, no extra cost)
    type: NodePort

is your kubernetes cluster reachable from the other cluster? may I know in which cloud you are running your cluster?

cluster is configured on a vm using k3s, and yes usually I expose services very similar even the frontend for signoz and its reachable.

So, you mean to say for collector even when it's exposed as a nodeport service and you are using external ip, still the collector is unreachable, correct? May I see you complete svc object that is being created in your k3s cluster?

I am using the official helm chart for that, after which a self hosted ingress

Is dns for the otel collector working? You can check by doing a curl from a pod where your tomcat app is running
