Hello,
I have a class that performs a graph and when it is completed I want to retrieve the number of records. My code looks like this:

result = runGraph.executeGraph(graph, runtimeContext);
while (result.isDone()) {;}
Map<String, Node> mapNodes = graph.getNodes();
Node node;
node = mapNodes.get("testNode");
int numRec = node.getInputPort(0).getInputRecordCounter();

but i get a NullPointer exception on loast istruction...What am I doing wrong?

  I modified the code in the following way and it's all ok:
  

  
  result = runGraph.executeGraph(graph, runtimeContext);
  Result resultR;
  resultR = result.get();
  Map<String, Node> mapNodes = graph.getNodes();
  Node node;
  node = mapNodes.get("testNode");
  int numRec = node.getInputPort(0).getInputRecordCounter();

  Probably the most convenient way how to get these type information is to use our JMX interface or for local purpose just call
  
  graph.getWatchdog().getCloverJMX().getGraphTracking()...
  
  CloverJMX is a JMX mbean which easily provides all the tracking information about running graph.
  
  If you decide to use direct the JMX interface, let me know to provide more information about that.
