Describe the solution you'd like
Topic of this ticket is: Advanced Debugging I.
Specific debugging items are yet to be determined, but a few options suggested by Valentin are:

• MS debugging
• low/high load in a system, i.e. why there are low number of workflows and how to address this. Does the system is over stressed with large number of workflows in a system and how to ease this situation
• CouchDB debugging
• MariaDB debugging and its queries
• WMA errors codes explanation and how to navigate them
• How to submit test workflow and debug its execution
• WMA state transition debugging

For the expected solution, please refer to the meta-issue for further details (in short: documentation + recorded presentation).
