## ๐ Code Review โ PR #11167
**Verdict: โ
Looks good**
This is a clean, minimal fix that addresses the silent exception swallowing
described in #11166.
### Analysis
| Aspect | Assessment |
|--------|-----------|
| Correctness | โ
`log` field is properly declared at L79 as `private static
final Logger` via `LoggerFactory` |
| Consistency | โ
Follows the existing pattern at L307 (`log.error("Failed
to get storage size", e)`) |
| Error messages | โ
Descriptive โ each message identifies which metric
failed (`dispatch-behind` / `dispatch-latency`) |
| Behavior preservation | โ
Catch blocks still exist; metric recording
continues for other gauges even if one fails |
| Scope | โ
Minimal โ 2 lines changed, 1 file, no unrelated modifications |
### Minor Observations
1. **No test coverage** โ The PR description notes that Maven/Java was not
available locally. Consider adding a unit test that verifies the `log.error`
path is exercised when `ConsumeQueueException` is thrown, to prevent regression.
2. **Metrics still report stale values on failure** โ When the exception is
caught and logged, the gauge simply does not record a new value for that
collection cycle. This is acceptable behavior, but worth documenting in the PR
description or a code comment for future maintainers.
Neither observation blocks this fix. The change is a clear improvement over
silently dropping exceptions.
