I think the cache monitor feature is neat and geeky, but I think “% of reads from cache” is a better number to consider. I realize you can calculate it, but I’d rather see % trended.
No system administrator or help desk technician has ever said “That’s way too much information, now I’ll never be able to fix it!”
i’d argue it shows too little, and on a graph that doesn’t scale correctly so mostly it doesn’t show useful information.
