By default nginx doesn’t cache anything the OS/Linux does it to reduce the 
diskreads. You can adjust it by tuning the 'vm.pagecache' and related sysctl

The pic doesn’t show anything specific to nginx except that you have 32 Gb 
of ram of what ~23 Gb are free ~7.7Gb are linux filesystem cache and 
something like ~2GB is used for apps etc.

To see what actually consumes the ram whole processlist would be needed and 
as people stated - also the output of nginx -V.
