<p>mainly you use ps for evaluating the pid of the process and use the proc filesystem to see the used files by the specific process.

<p>I need to analyze the file i/o operations caused due to a process. 
So I would like to know, which all files are affected by this program. Is there a tool for this particular use case?.</p>

<p>One of our debugging for a slow URL processing got the culprit being the file being read each time a URL was processed by the system. So I would like to get recommendations for a tool which would monitor the file activities per process.
Any suggestions?</p>
