Hi All,
How do we calculate the zfs cache value from Solaris 11.3 ?? I normally use memstat but learnt that is not a good practice. Any other way to get the value ?
Maybe you can find zfs-stats for Solaris?
If not, maybe you can get this older BSD version to work for you?

Can you elaborate more on need or problem to examine the cache usage ?
Are you having issues and what kind of workload is that ?
memstat/mdb should show correct cache usage.
I did see on 11.3 bugged output tho, so you should probably patch it up 
kstat is also quite verbose and correct.
Hope that helps
