Our application can embed/use link javamelody library, This enables us to gather some information about production context.
About link jdbc configuration, everything works as expected when

• no pool framework is used (or default one)
• c3p0 pool is used
  But using link HikariCP, neither sql requests /nor jdbc calls are logged.

Having a look at the HikariConnectionProvider and HikariConfigurationUtil classes (we are using 4.2 branches), we successfully make it work.

Changes we applyied

• method HibernateConfigurationUtil#loadConfiguration(Map props)

• // Do not move this line !
      HikariConfig hikariConfig = new HikariConfig(hikariProps);
  
      // if javamelody is used
      if(props.containsKey(DRIVER_ONLY)) {
        hikariConfig.addDataSourceProperty(DStringUtils.substringAfterLast(DRIVER_ONLY, "."), props.get(DRIVER_ONLY));
      }
      return hikariConfig;
  

where DRIVER_ONLY == hibernate.connection.driver

I didn't look further why this property can not be set as the previous ones, but it only works tihs way right now.

Let me know if you need any information.
Thanks,
