I want to edit the parsing of Novell Access manager 6.1r4 collector. I want only a sub-string in ExtendedInformation attribute instead of whole value which is coming. I read the documentation for customizing existing collectors. There it is written that, you will edit custom.js and add as an auxiliary file in that connector and execution mode will be change to custom.

For eg : Extended information -> Value2=0; Value3=0; JCC Device ID=ag-3994412863167286; MIMEtype=unknown; Event Identifier=3906; Target=Branding_URLs;

and i want to show only this part Target=Branding_URLs

But to change existing parsing for ExtendedInformation attribute, i need to know the existing code of this collector. Only then i can understand the changes i need to make. How can i get more information about this ?
