Why is my dependency showing as unknown

Elastic Observability APM

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?

Which db are you using?

MySQL
Here's my db config

spring:
  datasource:
    url: jdbc:mysql://xx:xx/xxxxx?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&allowMultiQueries=true
    driver-class-name: com.mysql.jdbc.Driver
    username: xxxxx
    password: xxxxxx
    type: com.zaxxer.hikari.HikariDataSource
    hikari:
      pool-name: DatebookHikariCP
      minimum-idle: 5
      maximum-pool-size: 30
      idle-timeout: 600000
      max-lifetime: 1800000
      connection-timeout: 30000
      connection-test-query: SELECT 1 FROM dual

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
