Is there a bug in internal metrics on 0.45.0

[satellite-no]

Im running vector 0.45.0 (x86_64-unknown-linux-gnu 063cabb 2025-02-24 14:52:02.810034614) on three seperate Vector instances and when I tap the outputs of the internal_metrics source i do not get any data. Also all of my data that has feed my promtheus dashboard from this source has stopped work.

example configs:
Source

type: "internal_metrics"
scrape_interval_secs: 10

Transform:

type: "remap"
inputs:
  - vector_internal_host_metrics
  - vector_internal_metrics
source: |
  .tags.vector_source = "Vector Internal Metrics"
  .tags.App         = "ABC123"
  .tags.Sources       = "Vector Internal"
  .tags.Ci            = del(.tags.host)

Sink:

type: prometheus_exporter
inputs:
  - core_metric_vector_tags
address: 0.0.0.0:9598
flush_period_secs: 60
auth:
  token: <token>
  strategy: bearer
buffer:
  type: "disk"
  max_size: 53687091200
  when_full: "block"

Hi @satellite-no, I just ran a pipeline locally and I am seeing metrics. I don't recall any recent changes to the internal metrics code parts. Are you see any events at all in your pipeline?

[satellite-no]

Thats the stange thing, vector top shows thousants of events from internal_metrics and incrometing but tap shows nothing. But from what I can see im not really seeing much of any data which i should see a lot.

[satellite-no]

For exampel I should have thousands and events according to vector top on otel.traces but when i tap that I see nothing and from what I can tell logs stopped processing to sinks as well.

Nevermind!! found its backpressure! shouldhave checked that first.
