measure size of queued messages - how identify how many messages >10k shipped ?

Hi @mathaase,
three options come to my mind:

Option 1:

In your consumer queue set "max msg size allowed" to 10K.

Then, all messages > 10K are discarded from your consumer queue and you can see discard statistics for that queue..
Disadvantage: They are NOT available in the queue to the customer.

Option 2:

Setup a new audit queue with subscription to the topics you're interested in.
Set the "max msg size allowed"
Set "TTL" to a short time (e.g. 20 seconds...) - so this queue wont be filled with messages

If you're just interested in a statistics, you can check discards on that audit queue for "message too big".

Option 3:

(derived from: https://docs.solace.com/Solace-PubSub-Event-Reference/event_ref_boiler.html#CLIENT_CLIENT_LARGE_MESSAGE)

Set the large-message-threshold in the message-vpn

setting in the cli
ena
conf
message-vpn xxx
event
large-message-threshold 10000

=> With this config, you will see one-shot events (that have to be cleared afterwards) in event.log
BUT: You can't identify the content of the message
