MBM counters are monotonically increasing counts representing the total memory bytes at a particular time. In order to calculate total_bytes for an rdtgroup, we store the value of the counter when we create an rdtgroup or when a new domain comes online. When the total_bytes(all memory controller bytes) or local_bytes(local memory controller bytes) file in "mon_data" is read it shows the total bytes for that rdtgroup since its creation. User can snapshot this at different time intervals to obtain bytes/second.
