strace fills the bill if you know what process (or its children) you
want to watch, and you can start that process manually.

If you don't know what process you want to watch, or there are a set
of unrelated processes, strace isn't very useful.  In that case you
can use systemtap to monitor open operations on a particular file.

It takes a bit more work to use systemtap than it does to use strace,
but in many ways it's a lot more flexible and powerful:
