Does this look ok? Just added domain in the text.
"The number of monitoring counters available in each domain for

The resctrl file system supports tracking up to two memory bandwidth
events per monitoring group: mbm_total_bytes and/or mbm_local_bytes.
Up to two counters can be assigned per monitoring group, one for each
memory bandwidth event in each domain. More monitoring groups can be
tracked by assigning one counter per monitoring group. However, doing so
limits memory bandwidth tracking to a single memory bandwidth event per
monitoring group."
Revised again:
"The number of monitoring counters available in each domain for
assignment when the system supports mbm_cntr_assign mode. For example,
on a system with 32 monitoring counters:
::
# cat /sys/fs/resctrl/info/L3_MON/num_mbm_cntrs
32
The resctrl file system supports tracking up to two memory bandwidth
events per monitoring group: mbm_total_bytes and/or mbm_local_bytes.
