Elastic Stack 8.13.3  
Java agent：apm-agent-attach-cli-1.52.0.jar

How does apm-agent obtain dependencies? Why can't this DB get the dependency name?

Best guess is that the Hikari driver is returning something we're not recognizing. If you can put together a reproducible test case that we can run, we'll have a look at it

Sorry, I can't provide reproducible test cases.  
I observed for a while and found that one of the apps could detect the DB information when it started monitoring, but after a while it became unknown. You can see that the monitoring curve in the picture is a connection.

The agent logs don't have much useful information
