NAME

lpana − print LP spooler performance analysis information

SYNOPSIS

lpana [−ddest ]

DESCRIPTION

Lpana prints information about the current performance of the LP line printer system for use by system administrators when determining how to configure the entire spooler system for optimum operation. 

One option is supported:

−ddest Choose dest as the printer or the class of printers.  If dest is a printer, the performance analysis information is printed on that specific printer.  If dest is a class of printers, the performance analysis information is printed on the printers that are members of the class.  By default, lpana prints the performance analysis information for all printers and/or classes. 

Lpana examines /usr/spool/lp/lpana.log for the following items:

Wait AV Average of waiting time to start to print after being queued into spooler. 

Wait SD Standard Deviation for waiting time. 

Print AV Average of printing time to have been completed after being started to print. 

Print SD Standard Deviation for printing time. 

Bytes AV Average of number of bytes to being printed per request. 

Bytes SD Standard Deviation for number of bytes. 

Sum KB Sum of bytes to have being printed for all requests in Kbytes. 

Num of Requests
Total number of requests from logging started.

In the HP Clustered environment, all printers are attached to the cluster server and all spooling is handled as if the cluster were a single system. Remote spooling applies to spooling from or to machines outside of the cluster. 

WARNINGS

Lpana performs its operation on the local system (or HP cluster) only.
