The DCBM provides status and error ags allowing monitoring of its proper installation, its
readiness towards transactions, the fulllness of its logbook, its internal operation, among others.
Those ags are available under various formats as follows:
• In /status API: current status and errors
• In /legal API: transaction status
• In /ocmf API: OCMF EF and ST elds
Additionally, /logbook API keeps track of raised statuses when a new event occurs.
Refer to "7.6. Event logbook".
