ZFS file system - memory monitoring

I am working on a server where the 'root' user ZFS filesystem.

Now when I do Top commands it says only 750M free .But when I count the actual memory utilized it comes only to 12 GB and the total size of the server is 32G.

I think rest of the space is held up by ZFS file system.

Is there a way to find the actual free space left?I want the user to be alerted when the actual memory left is <500M

Are you on Solaris? If so do:
echo "::memstat" | mdb -k

Well, then you might want to ask your SysAdmin to execute this command for you.
