Subject Re: How do I see miss ratio?
Date Tue, 12 Mar 2019 19:16:42 GMT
Hi Bryan and community, 
    Thank you for your reply! Does the fresh indicates disk hits or both ram+disk hits? 

And also a few other questions, 
	What does the different colors mean in the output?  
	What does Fresh(ms) mean, the sentence on the documentation site does not make sense to me
(it says the average loop up time for fresh cache serving), but I am seeing a value of 400k,
I don’t think each lookup takes 400k ms. 

Thank you!
