   Jitsu's Live Events view provides a debugger showing function logs, warehouse batch statuses, streaming delivery results, and dead-lettered events, with a dead-letter queue and reprocessing worker for failed deliveries, and this data can now be exported to an external monitoring stack near real-time (Datadog, Grafana Cloud, New Relic, Elastic via OTLP). However, native alerting is limited to SOC2-oriented account-activity audit alerts, not specific per-destination delivery-failure alert rules/thresholds built into Jitsu itself.
