[ NAME ]
iSMprfarc - Summarizes statistic information and outputs to a file.
[ SYNOPSIS ]
iSMprfarc [-v] [-o Directory] [-d] File [File ...]
iSMprfarc [-v] -p Directory -hour Target Period of Summarizing
iSMprfarc [-v] -p Directory -day Target Period of Summarizing
[ DESCRIPTI/ON ]
iSMprfarc is a command which summarizes statistic information in the input statistic information file
and outputs the summarized statistic information to a file. Summarizing statistic information makes
the time density of the statistic information coarser but saves file capacity.
iSMprfarc creates a file (statistic information primary summarized file) which summarizes the statistic
information for one day in units of hours from the statistic information history file (primary
summarizing). Further more, it creates a file (statistic information secondary summarized file) which
summarizes the statistic information for one month in units of days from the primary summarized file
(secondary summarizing). Also, it can create a statistic information secondary summarized file
directly from the statistic information history file without creating a primary summarized file (direct
secondary summarizing).
iSMprfarc can summarize statistic information during the period the user specifies such as change of
date. The user can directly specify the statistic information file to summarize, or specify the statistic
information file indirectly by specifying the directory where the statistic information file exists and the
target period of summarizing.
(i)
File Specification
iSMprfarc enters the File Specification Mode if a file is specified in the argument and summarizes
statistic information by using the specified file as an input file. The summarized file is output to the
server.
