System Debug

Its very hectic to debug when we have too many script statements. Most of the time when we apply System.debug in our code with many script statement we get :

*********** MAXIMUM DEBUG LOG SIZE REACHED ***********

I get frustrated with this and started rolling over the pdf which says there is a solution for this. Now if I want to see a specific line debug which is coming almost in the end of our code so I will simply write this where I want to get the debug in my code :

System.debug(Logginglevel.ERROR , ' ::::::: My Debug :::::::::::::') ;  

And after this some steps to be done

1. Create Debug logs from "Monitoring"
2. Create Filters :
• Database : NONE
• Workflow : NONE
• Validation : NONE
• Callouts : NONE
• Apex Code : ERROR
• Apex Profiling : NONE
• Visualforce : NONE

So when I execute my code only debug with Logginglevel.ERROR will be displayed.
