Item discovery:
Description::
 Discovery of files or directories. 
  {asroot|aszabbix} - which permissions to use. Sudo must be installed for asroot
  directory - directory to scan
  mask - mask to search. Use % instead of * in mask. Like '%' to find all objects, '%.txt' to find all .txt files
  maxdepth - depth to search. 1 means only one directory, not subdirs
  type - Type of objects to find (f=file,d=dir,l=link)
  sort - how to sort results (name/[+-], du/[+-])
  maxobjects - maximum objects to find. 0 means no limit.
