Ability to view the undelivered messages #3998

Closed AvinashVenkatesaiah closed 6 months ago

AvinashVenkatesaiah commented 1 year ago

We use nats jetstream and have set up streams and consumers with "all" as the acknowledgement policy . Do we have an ability to view the undelivered messages becuase of the all acknowledgement policy . Based on our understanding , an all ack policy acknowledges all the prior messages as a result of which the messages may not be delivered . Would want to know if there is a way we can view such messages using either the nats cli or sdks

Should you select ExplicitAck instead?

Hello @derekcollison : Our use case demands we use the all acknolowdgement policy

You can get stream sequence number details on the pending messages and view them with direct gets from the stream by stream sequence number.
