What happened?

Description

I have otel + httpcheck receiver running from a docker container (podman) on my local network. It works fine except for following metrics that remain always at 0:
httpcheck_client_connection_duration_milliseconds
httpcheck_client_request_duration_milliseconds
httpcheck_dns_lookup_duration_milliseconds
httpcheck_response_duration_milliseconds
httpcheck_tls_handshake_duration_milliseconds

The global httpcheck time (httpcheck_duration_milliseconds) is however ok (between 20 and 40 ms for my targets).
Also the other metrics look good:
httpcheck_tls_cert_remaining_seconds
httpcheck_status
httpcheck_response_size_bytes

If I do a test of http timing with curl or blackbox exporter, I get consistent values, never at 0.

Steps to Reproduce

docker pull otel/opentelemetry-collector-contrib:0.148.0
Run the container with otel config like:

receivers:
httpcheck:
collection_interval: 30s
metrics:
httpcheck.dns.lookup.duration:
enabled: true
httpcheck.client.connection.duration:
enabled: true
httpcheck.tls.handshake.duration:
enabled: true
httpcheck.client.request.duration:
enabled: true
httpcheck.duration:
enabled: true
httpcheck.response.duration:
enabled: true
httpcheck.tls.cert_remaining:
enabled: true
httpcheck.validation.passed:
enabled: true
httpcheck.validation.failed:
enabled: true
httpcheck.response.size:
enabled: true
targets:
- endpoint: "http://url1"
timeout: 5s
- endpoint: "https://url2"
timeout: 5s
headers:
Token: XXXXXXXXXXXXXXX

exporters:
debug:
verbosity: detailed
prometheus:
endpoint: "0.0.0.0:9100"

service:
pipelines:
metrics:
receivers: [httpcheck]
exporters: [prometheus,debug]

Expected Result

Following metrics should not at 0:
httpcheck_client_connection_duration_milliseconds
httpcheck_client_request_duration_milliseconds
httpcheck_dns_lookup_duration_milliseconds
httpcheck_response_duration_milliseconds
httpcheck_tls_handshake_duration_milliseconds

Actual Result

Following metrics always at 0:
httpcheck_client_connection_duration_milliseconds
httpcheck_client_request_duration_milliseconds
httpcheck_dns_lookup_duration_milliseconds
httpcheck_response_duration_milliseconds
httpcheck_tls_handshake_duration_milliseconds

Collector version

0.148.0
