NAME

       lpana - display LP spooler performance analysis information

SYNOPSIS

       dest]

DESCRIPTION

       displays  LP  spooler performance information, which system administrators can use to optimize the configuration of the entire spooler sys-
       tem.

   Options
       recognizes one option:

	      Choose	     dest as the printer or the class of printers.  If dest is a printer, the performance  analysis  information  is  dis-
			     played  for that specific printer.  If dest is a class of printers, the performance analysis information is displayed
			     for the printers that are members of the class.  By default, displays the performance analysis  information  for  all
			     printers and/or classes.

       examines for the following items:

	      Average waiting time from when job is spooled until start of printing.

	      Standard Deviation for waiting time.

	      Average printing time from start to end of job.

	      Standard Deviation for printing time.

	      Average of number of bytes printed per request.

	      Standard Deviation for number of bytes.

	      Sum of bytes printed for all requests (in kilobytes).

	      Total number of requests since logging started.
