Obtaining AFP statistics

The AFP Statistics (AFPSTATS) option lets a user obtain detailed information about a print file. You specify it individually for each print file and you can view the data online or print it. PSF presents the data in an AFPSTATS report, which provides details to let you:

  • Determine in which resource library PSF found each resource.
  • Determine whether the file is MO:DCA IS/3.
  • Diagnose some resource selection problems.
  • Obtain statistical data about how a print file printed, such as the total number of pages, the number of times a specific resource was referenced, and the number of significant events. It is important to note that these statistics might contain some inaccuracies caused by error recovery and repositioning within the print file. Therefore, do not use these statistics for accounting purposes.
  • Diagnose some print file printing performance problems.

The AFPSTATS report summarizes these resource types:

  • Character set
  • Coded font
  • Code page
  • Form definition
  • Object container
  • Overlay
  • Page definition
  • Page segment
  • TrueType and OpenType fonts
Note:
When the AFPSTATS report is active, PSF is collecting data and writing it to the AFPSTATS repository. These extra activities during PSF processing could cause degraded performance. Whenever you experience a problem with performance, first ensure that all extra activity, such as PSF traces and reports, are disabled before confirming the performance problem.
