Hi @SUNA ,
When the internal queue fills up, this is mostly due to mapping mismatches if the index template setup wasn't successful or due to the APM Server being overloaded. Since you don't see any data in the Kibana UI, I suspect that something with the setup might be wrong. Currently we have too little details to make any more specific suggestions. As a start, you should take a look at the APM Server logs and check if there are any errors, indicating what is the root cause of the queue filling up.
If you share any error logs in this forum, please redact any sensitive information before sharing, and also include some meta information around the version, installation method and how you set up the Elasticsearch index templates.
The APM Server guide has a [troubleshooting section for when the queue fills up](https://www.elastic.co/guide/en/apm/guide/7.17/common-problems.html#queue-full), please give it a read.
