📝 WalkthroughWalkthroughAdds an executable Python CLI that builds HBI host events for multiple host types and organizations. It supports dry-run JSON output, Kafka transmission, provider and subscription metadata, guest mapping, billing fields, event timestamps, validation, and result reporting.

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to Non-dry-run executions currently fail while publishing host events because the Kafka message key is not encoded, so the requested test data is not sent.

In `@bin/send-hbi-host-events`:
- Around line 41-44: Update the timestamp setup around now, timestamp,
stale_timestamp, and stale_warning_timestamp to parse --last-seen into a
timezone-aware datetime, reject invalid input, and use that parsed value as the
lifecycle timestamp base; when --last-seen is absent, retain the current-time
base, and derive all generated timestamps consistently from it.
- Around line 264-267: Update the argument validation and generation flow around
build_host_event to calculate the total requested event count, including
--num-accounts, and reject a supplied --inventory-id unless that count is
exactly one. Preserve inventory ID handling for single-event requests and
prevent it from being reused across multi-host generation loops.
- Around line 8-12: Move the KafkaProducer import and its missing-dependency
exit handling from module scope into the non-dry-run branch after argument
parsing. Keep producer construction inside if not args.dry_run, so dry-run JSON
execution does not require kafka-python.
- Around line 133-147: Update send_events to retain the FutureRecordMetadata
returned by producer.send, call its get() before printing the success message,
and only report the event as sent after delivery succeeds; allow delivery
exceptions to propagate so the command exits nonzero while preserving dry-run
behavior.
- Around line 358-373: Update the host-event construction around
build_host_event so --unmapped-guests always supplies a non-empty generated
unknown hypervisor ID when no explicit hypervisor is provided, while explicit or
subscription-derived IDs are used only for mapped guests. Ensure the resulting
system_profile.virtual_host_uuid identifies an unknown hypervisor for unmapped
guests.
- Around line 37-38: Remove the unsupported billing_provider,
billing_account_id, and metric_id options from the HBI event flow, unless an
explicit payload mapping is implemented for them. Update the related dry-run
tests to verify the selected behavior and ensure these no-op options are not
exposed or silently accepted.

Couple things:
- We should set the message key to the target org since that's what HBI does today.
- Would prefer that the script used defined POJO objects to define the message data to avoid string based keys in a dict.
This only supports rhsm-conduit reported hosts, however, I think I'm Ok with keeping it simple for now since it'll mostly be used for local testing.

Recent changes covered my change requests. Found a small issue and pushed a fix.
I pushed a change to avoid sending None for all properties defined on the dataclass objects you've created. This fixes a breakage in the script.
Please give it a try. Other than that LGTM.

…nTest The test was failing in CI due to a race condition where the PostgreSQL container's "Starting server" log message appeared before the Unix socket was actually ready to accept connections. This caused the ALTER USER command to fail with "No such file or directory" on the socket. Changes: - Added retry logic (5 attempts with 1s delay) for the ALTER USER command - Added explicit 60s startup timeout to the wait strategy - Improved error message to indicate number of retry attempts This fixes the flaky test failure that was blocking PR #6507.
