Inside your DicomService, you can always look at this.Association

When you build up a DicomServer, then you create a class inheriting from DicomService. This class is then passed to your DicomServer as a generic Type-Parameter.
What you should know is, that the DicomServer creates a new instance of your DicomService class for every association. If there are several associations in parallel, then the DicomServer as a collection of your DicomService instances.
That said, you can add some private fields to your class, like timestampStart or instancesCount.

public class MyDicomService : DicomService, IDicomServiceProvider, IDicomCStoreProvider
{
   private DateTime _associationStarted;
   private int _instancesCount = 0;

   public Task OnReceiveAssociationRequestAsync(DicomAssociation association)
   {
      // we can know which client it is by use association
   _associationStarted = DateTime.Now;
   }

   public Task OnCStoreRequestAsync(DicomCStoreRequest request)
   {
      // you could check the client/association connected to this instance by accessing the Association-property
      var client = Association.CallingAE;
      _instancesCount ++;
   }

   public Task OnReceiveAssociationReleaseRequestAsync()
   {
      // here on release you can access all fields and the Association property
      Logger.Log($"client {Association.CallingAE} sent {_instancesCount} instances and took {(DateTime.Now - _associationStarted).TotalSeconds} seconds");
      return SendAssociationReleaseResponseAsync();
   }
}

Thank you very much for your detailed reply, it helped me a lot
