I have searched but cannot find any documentation or discussion on how to test the DLQ in 7.4.
I have set the logstash.yml for DLQ as:
But how to test this works? All of the help on this site explains
- that you can only use it with an ElasticSearch output.
- message are only sent to the DLQ when a 400 or 403 occurs
- has examples on how to input message that exist in a DLQ
So any advice on how to actually get a message to show up in the DLQ would be appreciated.
