Hello. I cache contents with NGINX proxy\_cache in all my sites but I’m  
not sure I’ve the best setup.

Are there rules/hints to properly set the size and/or the TTL for the  
cache ?  
Would be nice to have a tool that monitor/track files written in the  
cache and those deleted (an the reason as well)

Is there such a tool or can I enable some logging feature to get these  
data ?

Thanks
