It seems vector doesn't send log message to the server.

[JayJay-K]

I'm trying to deploy vector on the kubernetes environment.
I succeeded to run vector pods (daemonset)

Now, I hope to gather log data from the file "/var/run/cilium/tetragon/tetragon.log"
and send it to a specific server with http protocol.
But, it seems that the log data is not being transmitted.

This is pod list (it looks OK):

$ kubectl -n tetns get pod
NAME                                READY   STATUS    RESTARTS   AGE
tetragon-6j9fx                      2/2     Running   0          11d
tetragon-operator-84b7df4c4-wrscf   1/1     Running   0          11d
vector-ggf62                        1/1     Running   0          21m

This is my config file, values-vector.yaml

#values-vector.yaml
role: "Agent"

tolerations:
- operator: Exists

service:
  ports:
  - name: prom-exporter
    port: 9598

containerPorts:
- name: prom-exporter
  containerPort: 9598
  protocol: TCP

customConfig:
  sources:
    tet_in:
      type: file
      include:
      - /var/run/cilium/tetragon/tetragon.log

  sinks:
    tet_out:
      inputs:
      - tet_in
      encoding:
        codec: text

      type: http
      uri: http://192.168.112.35:54333

I couldn't see any message when I tried to capture http message with port 54333 between worker-node and server.
I think vector doesn't send http message to the server.

This is a vector log:

I checked that log file "/var/run/cilium/tetragon/tetragon.log" is being updated continuously.
Could you please give some advice for this problem?

Thanks.

Hello.

I realiased that I should add '/var/run/cilium/tetragon/' to the mountPath and hostPath in values.yaml.

Thanks.
