The imsimta qm messages utility displays the number of messages queued for the channel given. Separate counts are given for messages that are ready to be processes (or are being processed) and those messages that have been tried and are awaiting their retry backoff. For channels where the destination host is significant, in particular the tcp_* channels, the messages are displayed by destination host.
