Hi,

Received a Database cache hit ratio warning alert from one of the monitoring tools, the threshold for the “database cache hit ratio %” is 90% for a High and 95% for Critical

Does this unnamed monitoring tool (and undefined query) really think higher percentages are worse or are you mis-communicating?
