    I think i know the issue. I created a queue and add the topic to queue subscription. As a result, the number of message spool ingress discard did not increase.

    I guess it was because i am publish direct message to the broker with no topic subscription to any queue or client. As a result, the messages are discarded by the broker.

    Publishing messages as Direct shouldn't affect your message-spool stats? Unless promotion is occurring and something is wrong with a queue (e.g. over quota). If you do a show message-spool stats it should provide a breakdown of that top-line number:

    show message-spool stats
