GOAL:
Fathom: Information about BufferIOHigh rule.
FIX:
BufferIoHigh is the ratio of _ActSummary.DbReads and _ActSummary.dbWrites (in other words the number of DB block reads compared to the number of DB block writes). The threshold indicating units of "bytes" is a mistake. This is a straight ratio that will fire when the number of reads / writes falls below 75 : 1 (by default).
The normal expectation is that there are a lot more reads going on than writes. This would need to be adjusted based on the nature of the actual application and historical knowledge of what "normal" would should be.
