How to check replication latency and data loss in the Cross Cluster Replication of Elasticsearch? When we implement CCR how we can ensure the accuracy and efficiency of the replication. Please suggest any tool or .Net client to achieve this testing. How to perform failover and failback testing?

Welcome to our community! 😃

[Manage cross-cluster replication | Elasticsearch Guide [7.16] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/7.16/ccr-managing.html#ccr-inspect-progress) has information on that.
