10.4.10. View Resilient Connections

The command link list can be used to show the resilient connections for a broker:
$ qpid-route link list localhost:10001

Host            Port    Transport Durable  State             Last Error
=============================================================================
localhost       10002   tcp          N     Operational       
localhost       10003   tcp          N     Operational       
localhost       10009   tcp          N     Waiting           Connection refused
In the above output, Last Error contains the string representation of the last connection error received for the connection. State represents the state of the connection, and may be one of the following values:
