Impossible to initiliaze a run with the monitoring enabled

Summary

As soon as the monitoring application is included into a xDAQ configuration tailored to take a run (i.e. including the GEMSupervisor), initialization is impossible, the transition goes into a infinite loop with the error messages shown below.

Steps to reproduce

  1. Start xDAQ with a configuration including both the GEMSupervisor and monitoring application
  2. Take all your time to make yourself a coffee... ☕

What is the expected correct behavior?

The initialize transition should succeed.

Environment

Possible fixes

  • Fix the state retrieval in the monitoring applications (FSM is different than for data-taking applications)
  • Exclude the monitoring application from the supervised applications
