Solace Community is getting a facelift!
On March 3rd we will be starting the process of migrating Solace Community to a new platform. As a result, Solace Community will go in to a temporary read-only state. You will still be able to come onto Solace Community and search through posts to find answers, but you won't be able to ask questions, post comments, or react in any way.
We hope to have the migration complete by Wednesday March 5th (or sooner), so please keep an eye out!
How to get and test information on discarded messages
Problem
You see that you are having a lot of ingress discards due to No Subscription Match and are looking for more information about these messages. The information that might be pertinent is: Topic, Client Username, and Message VPN name.
Solution
Use the following command to get the information about the messages:
solace> show log no-subscription-match [client-username <username>][client-name <name>] [message-vpn <vpn-name>] [wide]
You will then be able to see the Topic, Client Username, and Message VPN name on the last 1,000 discarded messages.

You can use SDKPerf to test if the solution works. Here is an example for publishing a single message with no topic match:
[wskinner@dev3-225 ~]$ sdkperf_c_d36 -cip=192.168.164.199 -cu=default@default -ptl=topic -mn=1 -mt=persistent -msa=10
Result
Here you can see the CLI output:
vmr-132-44> show log no-subscription-match
Most recent no-subscription-match events:
| Client | Username | Message VPN | Topic |
|---|---|---|---|
| dev3-225/9209/#00000001 | default | default | topic`` |
