title: Parameters to watch while running an application on linux?
body: <p>I am running an application overnight on my Linux xscale device. I am looking for things,which would increase with the increase in the amount of time of running.
  One thing,is the memory. If you observe the memory on the xscale systems,the free memory would start decreasing,but you will see an increase in the cached memory. What are the other parameters which we can observe ,e.g. can we observe the amount of stack or heap usage?</p>
