MeterRegistry using in the Map

Question

I have this code:

static method(){ // also other class called this method
for (Map.Entry<String, DataSource> dataSource :dbhealth.entrySet()) {
      Connection connection = dataSource.getValue().getConnection()
       if (!connection.isValid(timeout)) {
          log("bd connection is not valid for"+, dataSource.getKey());
         } 
}}

Here, dbhealth is a Map<String, DataSource> which stores health information. How can I get the MeterRegistry to alert the user if the connection has timed out?

I considered creating a new method to put in the constructor like so:

public xxx(xx,xx, MeterRegistry meterRegistry){
for (Map.Entry<String, DataSource> dataSource :dbhealth.entrySet()) {
      Connection connection = dataSource.getValue().getConnection()
      boolean connected = connection.isValid(timeout)
         if(meterRegistry!=null){
            Gauge.builder(C.Metrics.DS_HEALTH, () -> (connected) ? 1 : 0)
                    .register(meterRegistry);
        }
      } 
}

But this looks strange, and seems to duplicate code. Is there a more direct way to solve the problem?
