To display the compression ratio for the ZFS dataset /var/log on the pool
mypool, run the following command:

zfs get refcompressratio mypool/var/log

The refcompressratio will only display the compression ratio for that specific
dataset, not the descendant datasets. To include the child datasets, the
command looks like this:

zfs get compressratio mypool/var
