…ures When notification delivery fails, the dispatcher error log only exposed receiver/integration inside the free-text err string. Annotate RetryStage failures with ErrorWithIntegration and attach receiver/integration as structured fields on the dispatch failure log so operators can group by them in log aggregators without regex-parsing err.

Hi @locker95 ,
thanks for updating the PR. However, I'm afraid that we have an issue here, which cannot be resolved easily:
func (fs FanoutStage) Exec(ctx context.Context, l *slog.Logger, alerts ...*alert.Alert) (context.Context, []*alert.Alert, error) {
var (
wg sync.WaitGroup
mtx sync.Mutex
errs []error
)
wg.Add(len(fs))
for _, s := range fs {
go func(s Stage) {
if _, _, err := s.Exec(ctx, l, alerts...); err != nil {
mtx.Lock()
errs = append(errs, err)
mtx.Unlock()
}
wg.Done()
}(s)
}
wg.Wait()
// Joining once keeps one element per stage. Joining pairwise as the errors
// arrive would nest them, and callers could no longer tell which stage each
// one came from.
return ctx, alerts, errors.Join(errs...)
}This code will join the error, and thus the logging in the dispatcher is not reliable with respect to integration specific code. The correct thing to do is to log the integration specific code in the RetryStage. However, we already have that for retry codes. So, the only thing that is available is the receiver at the dispatcher level. I looked at some other possibilities:
- Walk the joined error to recover the information. This get's a definite no from me, since it is adding complexity, where we should be remove complexity.
- Don't log an error in the dispatcher at all, just log in the respective notification stages. This one is very error prone in the current setup. Due to the stages, we can't log the errors once before the fanout, and once per fanout stage. Thus, I'm not comfortable with such a change either.
So, for now please just add the receiver label to the dispatcher. Don't close the original issue with a fixes trailer.
Fanout joins errors, so an integration field on the dispatcher line isn't reliable. Leave integration in the error text; RetryStage already logs it on retries. Signed-off-by: Dean Chen <862469039@qq.com>

yeah, the joined fanout error makes the integration field a mess. dropped that wrapper and the extra field — dispatcher now just logs also took the Fixes trailer off so this doesn't close the issue. |

Summary
When a notification send fails, the dispatcher logs
Notify for alerts failedwith onlyaggrGroup,num_alerts, anderras structured fields. The receiver name and integration (e.g.slack[0]) are present only inside the free-texterrstring, which makes log aggregation (Loki/ELK) brittle.Changes
notify.ErrorWithIntegrationto annotate RetryStage failures withreceiverandintegrationreceiver(from the aggregation group) andintegration(when available viaerrors.As) as structured fields on the dispatch failure logChannel is intentionally out of scope here: it is integration-specific and already appears in some integration error messages (e.g. Slack). Receiver/integration alone cover the main operator need from #5396.
