CF ingress receivers

otlp/cf-internal-local is the stable, release-managed receiver reference. Its definition comes from ingress.grpc.* and overrides any operator definition. The otlp/cf-internal-local receiver definition is always supplied by this BOSH release.

ingress.pipelines	Other receiver definitions	Pipeline receiver lists
Unset (default)	Discarded	All replaced with [otlp/cf-internal-local]
[]	Preserved	Unchanged (manual wiring)
Nonempty list	Preserved	Only selected lists replaced

For manual or mixed receivers, use [] and wire lists such as [otlp/cf-internal-local, otlp/custom] yourself.

Define custom receivers under config.receivers in the otel configuration supplied to this release and reference them in the relevant pipeline's receivers list. Configure ingress.pipelines to contain only those pipelines in which otlp/cf-internal-local shall be the only receiver (can also be []). This way custom receiver references are preserved.

Only unset/null selection adds nop pipelines for missing CF signals, for backward compatibility. Explicit lists and [] add no fallbacks; operators own signal handling.

FAQ

How do I configure mTLS per exporter?

Put each exporter's PEMs under config and reference CredHub-stored values via BOSH ((var)) placeholders:

config:
  exporters:
    otlp_grpc/prod:
      endpoint: prod-backend:4317
      tls:
        ca_pem:   ((prod_ca))
        cert_pem: ((prod_cert))
        key_pem:  ((prod_key))
    otlp_grpc/staging:
      endpoint: staging-backend:4317
      tls:
        ca_pem:   ((staging_ca))
        cert_pem: ((staging_cert))
        key_pem:  ((staging_key))
  service:
    pipelines:
      metrics:
        exporters: [otlp_grpc/prod, otlp_grpc/staging]

If config must be a YAML string instead of a map, BOSH ((var)) substitution cannot indent multi-line PEMs into the block scalar and template rendering fails. In that case use the secrets property — see the secrets description in the job spec.
