# Recovering, Tracing and Monitoring

To keep the system reliable and resilient it's important to handle errors with grace.\
Ecotone provides solutions to handle failures within the system that helps in:

* Self-healing the application ([Instant and Delayed Message Handling Retries](https://docs.ecotone.tech/modelling/recovering-tracing-and-monitoring/resiliency/retries), [Locking](https://docs.ecotone.tech/modelling/recovering-tracing-and-monitoring/resiliency/concurrency-handling), [Isolation of failures](https://docs.ecotone.tech/modelling/recovering-tracing-and-monitoring/message-handling-isolation))
* Ensuring Data Consistency ([Resilient Message Sending](https://docs.ecotone.tech/modelling/recovering-tracing-and-monitoring/resiliency/resilient-sending), [Outbox pattern](https://docs.ecotone.tech/modelling/recovering-tracing-and-monitoring/resiliency/outbox-pattern), [Message Deduplication](https://docs.ecotone.tech/modelling/recovering-tracing-and-monitoring/resiliency/idempotent-consumer-deduplication))
* Recovering ([Dead Letter](https://docs.ecotone.tech/modelling/recovering-tracing-and-monitoring/resiliency/error-channel-and-dead-letter), [Tracing](https://docs.ecotone.tech/modules/opentelemetry-tracing-and-metrics), [Monitoring](https://docs.ecotone.tech/modelling/recovering-tracing-and-monitoring/ecotone-pulse-service-dashboard))
