Find out Consumers of Particular topic

[Muni]

Hi All,
How do you find out list of consumers of a particular topic? Would we be able to search who all consuming the given topic?
Let us say, I have below queues subcritpion

Q1 - hello/first
Q2 - hello/second
Q3 - hello/first
Q4 - hello/first

How do you find out the list of Queues who are consuming topics hello/first?

Hey @Muni > - you can leverage the details exposed by SMRP (solace Subscription Management and Routing Protocol) to get a list of queues subscribed to the topic of choice
show smrp subscriptions topic hello/first
You can also check further details here

Yup, good ol’ SMRP (Solace’s Subscription Management and Routing Protocol)…! ?

Note that if you’re looking specifically for queue subscriptions, then I’d suggest adding the term “persistent” to your command. E.g.: show smrp subscriptions message-vpn [VPN] topic [TOPIC] persistent

Also, the typo above (subscription vs. subscriptions).

When providing the TOPIC to look for, you can use the wildcard asterisk *. But this is not the same a the topic wildcard… it will match any number of chars. And > doesn’t work as a wildcard either:

0c6dd5f754be> show smrp subscriptions message-vpn default topic solace* persistent

Flags Legend:
T - Destination Type (C=local-client, Q=local-queue
       T=local-topic-endpoint, R=remote-router)
P - Subscription Persistence (P=persistent, N=non-persistent)
R - Redundancy Type for Local Destinations (P=primary, B=backup
       S=static -=not-applicable)

Message VPN : default (exported: No; 100% complete)
Destination Name         Flags BlkID DTO  Subscription
                         T P R       Prio
------------------------ - - - ----- ---- ------------------------------------
q1                       Q P P     0   DA solace/*
q_pers_processor         Q P P     0   DA solace/samples/*/pers/pub/>
q_samples                Q P P     0   DA solace/samples/*/pers/>
q_samples                Q P P     0   DA solace/samples/*/pers/pub/>
0c6dd5f754be>

Finally, there is a SEMPv1 command for this, rather than having to use the CLI:

<rpc semp-version="soltr/9_9VMR">
    <show>
        <smrp>
            <subscriptions>
                <vpn-name>default</vpn-name>
                <topic></topic>
                <topic-str>solace*</topic-str>
                <persistent></persistent>
            </subscriptions>
        </smrp>
    </show>
</rpc>

Hope that helps anybody else in the future.

Maybe I should join the Support team?? haha

Hint: if you search for SMRP in the solace community you will get quite a few interesting posts as well that might be helpful.
