> An agent collects per process CPU stats by using the following: 
>  top -b -n 1 -p "+pid+" | tail -n 2 | head -n 1 | awk '{print $9}';
> The above seems to cause a NumberFormatException while trying to convert scraped output into an integer. The exception is:
> java.lang.NumberFormatException: For input string: "%CPU"
>         at java.lang.NumberFormatException.forInputString(NumberFormatException.java:76)
>         at java.lang.Integer.parseInt(Integer.java:492)
>         at java.lang.Integer.valueOf(Integer.java:593)
>         at org.apache.uima.ducc.agent.processors.LinuxProcessMetricsProcessor.collectProcessCurrentCPU(LinuxProcessMetricsProce\ssor.java:462)
>  
> When running the command by hand I seem to be getting a numeric value.
