iostat -x 2 sda
The '-x' option will repeatedly print the statistics at the given
interval (seconds). You can (optionally) also give the name(s) of
devices for each drive.
So, assuming that your ZK transaction log (specified in
$ZOOKEEPER_HOME/conf/zoo.cfg under the 'dataDir' key) is mounted on
/dev/sda, the above command would list statistics every 2 seconds until
you ctrl-C the process.
