Hi,
I have monitored that disk utilization is very high on one of red hat linux VM.
Would like to know how to find out that issue of high disk utilization is because of disk or Installed Application on that server is causing the problem.

memstat
MEMSTAT(1) Linux Programmer's Manual MEMSTAT(1)NAME
memstat - Identify what's using up virtual memory.
SYNOPSIS
memstat [-w][-p PID]
DESCRIPTION
memstat lists all accessible processes, executables, and shared libraries that are using up virtual memory. To get a complete list memstat
has to be run as root to be able to access the data of all running processes.
First, the processes are listed. An amount of memory is shown along with a process ID and the name of the executable which the process is
running. The amount of memory shown does not include shared memory: it only includes memory which is private to that process. So, if a
process is using a shared library like libc, the memory used to hold that library is not included. The memory used to hold the exe-
cutable's text-segment is also not included, since that too is shareable.
After the processes, the shared objects are listed. The amount of memory is shown along with the filename of the shared object, followed
by a list of the processes using the shared object. The memory is listed as the total amount of memory allocated to this object throughout
the whole namespace. In brackets also the amount that is really shared is listed.
Finally, a grand total is shown. Note that this program shows the amount of virtual (not real) memory used by the various items.
memstat gets its input from the /proc filesystem. This must be compiled into your kernel and mounted for memstat to work. The pathnames
shown next to the shared objects are determined by scanning the disk. memstat uses a configuration file, /etc/memstat.conf, to determine
which directories to scan. This file should include all the major bin and lib directories in your system, as well as the /dev directory.
If you run an executable which is not in one of these directories, it will be listed by memstat as ``[0dev]:<inode>''.
Options
The -w switch causes a wide printout: lines are not truncated at 80 columns.
The -p switch causes memstat to only print data gathered from looking at the process with the gicen PID.
NOTES
These reports are intended to help identify programs that are using an excessive amount of memory, and to reduce overall memory waste.
FILES
/etc/memstat.conf
/proc/*/maps
SEE ALSO ps(1), top(1), free(1), vmstat(8), lsof(8), /usr/share/doc/memstat/memstat-tutorial.txt.gz
BUGS
memstat ignores all devices that just map main memory, though this may cause memstat to ignore some memory usage.
Memory used by the kernel itself is not listed.
