sysdig is a great solution now.
Some usage cases include (their wiki has some exceptionally interesting examples):
See the top processes in terms of disk bandwidth usage
sysdig -c topprocs_file
List the processes that are using a high number of files
sysdig -c fdcount_by proc.name "fd.type=file"
See the top files in terms of read+write bytes
sysdig -c topfiles_bytes
Print the top files that apache has been reading from or writing to
sysdig -c topfiles_bytes proc.name=httpd
Basic opensnoop: snoop file opens as they occur
sysdig -p "%12user.name %6proc.pid %12proc.name %3fd.num %fd.typechar %fd.name" evt.type=open
See the top directories in terms of R+W disk activity
sysdig -c fdbytes_by fd.directory "fd.type=file"
See the top files in terms of R+W disk activity in the /tmp directory
sysdig -c fdbytes_by fd.filename "fd.directory=/tmp/"
Observe the I/O activity on all the files named ‘passwd‘
sysdig -A -c echo_fds "fd.filename=passwd"
Display I/O activity by FD type
sysdig -c fdbytes_by fd.type
