Aggregated Status
We would perhaps consider this a status like any other, just defined to indicate the overall status of all components. It would be linked to the main component. Eg:
status/<id>/main/system/aggregated
An option would also be to split each aggregated status part into topics: status/<id>/main/system/aggregated/high
status/<id>/main/system/aggregated/low
status/<id>/main/system/aggregated/local_mode
