I want to create some metrics around step functions that we currently have. I was able to make that list using python but for some reason, we are limited to use java in our company.

I want to

List ALL statemachines which are defined in current region for given account. in python i was able to achieve this using 

stepFunction = boto3.client('stepfunctions', region_name='eu-west-1')
stepFunction.list_state_machines()

Then from that, i want to list all Tasks for that given statemachine and get some metrics.

In Java, I am unable to find an API reference which will give me ALL statemachines. I was looking at http://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/index.html?com/amazonaws/services/stepfunctions/model/ListStateMachinesRequest.html API but no help.

To get the activity tasks for every state machine in your library, you will need to use the describeStateMachine call. Follow this pattern (please excuse the pseudocode):

state_machines = list_state_machines()
for each (state machine arn : state_machines) 
  sm = describe_statemachine(state_machine_arn)
  /*parse through the definition here and use regex pattern on the arns*/
  activityarns = sm.getDefinition().find(/regex/)

  metrics.add(sm.arn, activityarns)
endforeach

Hope this helps!
