'time' for disk stats

we all know the time shell command

Is there a way to test disk i/o of a process in a similar fashion?

I am trying different methods to limit disk writes in a 24/7 daemon process and would like to

with the daemon not running continuously.

NAME
lsmsad - Starts the Storage Administrator (SA) daemon SYNOPSIS
/usr/sbin/lsmsad DESCRIPTION
The SA daemon, lsmsad, is a process required by lsmsa, the SA graphical user interface (GUI). The daemon issues commands and obtains system information on behalf of SA. The SA daemon runs on a Tru64 UNIX system on which LSM is initialized and running. The SA client runs on any machine that supports the Java Runtime Environment. The SA daemon is automatically started at boot time. Under normal conditions, the daemon does not need to be run manually. If SA does not start during the boot process, enter: /sbin/init.d/lsmsa stop To restart SA, enter: /sbin/init.d/lsmsa start Only one SA daemon can be running on a system at a given time. If a second SA daemon attempts to start, it will fail. RESTRICTIONS
You must be root user to run lsmsad. FILES
The script that starts lsmsad at boot time. The command log file that tracks SA tasks. The access log file that tracks login to SA. The server log file that tracks server startup information and server errors. The log maintenance shell script that saves and compresses log files. SEE ALSO
