Following are examples of running sh_stat.d on Shell scripts. 

sh_stat.d shows you the number of events per second that have happened since
the last line output.  The default interval is 1 second, but you can specify 
other intervals as arguments to the script.

This shows the sh_stat.d script reflecting the Code/Shell/func_slow.sh script.
