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

Forget about the tool used for monitoring, important is to monitor the "Cache hit ratio" is good or we can ignore it?

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
