There are a few ways of taking a high level overview of processes. The first is to leverage the Exceptions tab that you will see at the top of the screen. This will navigate you to a list of all exceptions across all of the processes you have visibility to. You can then click on one of these processes to drill down into the breaks by run and by age.
There are also gadgets for the dashboard that could prove useful for high level analytics. For example, there is a "Labels" gadget which shows you how many times a label had been applied across all processes you have visibility to. You can also use the Process Groups gadget to see aggregate results for reconciliations, grouped per your requirements.
To see more granular metrics around exceptions, such as break trending (trending by breaking field or by counterparty, for example) or break assignment by user, across multiple processes, then you would require access to the Duco Data Platform.
