Internal Metrics not reporting for one source

[generate-me12]

Question

Hi, I'm trying to use internal metrics source to get the component_received_events_total for the 3 sources but I'm only getting the metrics for 2 sources and for some reason the http_source doesn't report, I'm only getting the metrics for the two sources instead of 3. Even if i'm not using http, I should have a metric with value of 0.0 right? I have shown a subset of config below.

Vector Config

sources:
  vector_internal_metrics:
    type: internal_metrics
    namespace: vector
    scrape_interval_secs: 30

  http_source:
    type: http
    address: 0.0.0.0:12345
    encoding: text
    path: /random/log
    strict_path: true

  tcp_source:
    type: socket
    mode: tcp
    address: 0.0.0.0:54321

  udp_source:
    type: socket
    mode: unix_stream
    path: /tmp/my_sock

transforms:
  metrics_filter:
    type: filter
    inputs:
      - vector_internal_metrics
    condition: .name == "component_received_events_total" && ( .tags.component_id == "tcp_source" || .tags.component_id == "otel_source" || .tags.component_id == "http_source")

sinks:
  internal_metrics_sink:
    type: file
    inputs:
      - internal_metrics_filter
    compression: none
    path: "/my/path/internal_metrics.log"
    encoding:
      codec: json

Hi @generate-me12, did you close this on purpose? Did you figure it out?

Hi, yes, I realize that it starts reporting after I send one test request to the http source so I'm guessing it has to be used at least once before reporting metrics
