Hi,
We're trying to find out how to retrieve the current number of queue consumers (TCP sessions) using the SEMP V2 API. The response of "GET SEMP/v2/monitor/msgVpns/{msgVpnName}/queues/{queueName}" does not contain this.

Thank you :smile:

    Hi @sjaak -
    The number of consumers and details about the conumsers can be obtained via the txFlows sub resource of the Queue API.

    "GET /msgVpns/{msgVpnName}/queues/{queueName}/txFlows"
    (https://docs.solace.com/API-Developer-Online-Ref-Documentation/swagger-ui/monitor/index.html#/queue/getMsgVpnQueueTxFlows)

    The return value is an array with one entry per consumer flow, i.e. the length of the array is equal to the number of consumers (Queue Transmit Flows are used by clients to consume Guaranteed messages from a Queue).

    I just quickly looked through the monitor and config sections of the SEMPv2 API, and am surprised that just regular (current) "bind count" doesn't seem to be in there. I don't think you should have to get an array of flow objects to just get the count, especially since it's there in SEMPv1.

    @Aaron The element is called "count" in the TxFlows response. Works :smile:

    Sure, but I still disagree with having to get all the Tx Flows just to get the count. Perhaps that's just the old-schooler SEMPv1'er in me talking.

    I agree. This can be simplified :smile:
