If you’d like a command-line utility (Java) to browse queues, you can check out:
It’s similar to SdkPerf (which can also browse queues!) but can pretty-print certain payloads.
$ bin/PrettyDump aaron.messaging.solace.cloud aaron-demo-singapore me pw b:q1
PrettyDump initializing...
PrettyDump connected to VPN 'aaron-demo-singapore' on broker 'aaron.messaging.solace.cloud'.
Attempting to browse queue 'q1' on the broker... success!
Browse all messages -> press [ENTER],
or enter specific Message ID,
or range of IDs (e.g. "25909-26183" or "9517-"): 31737085
So you can enter either a specific message ID, a range, or just all messages on the queue. Also: you can use the shorthand f:<queueName> instead to just browse the latest message off a queue and then exit.
