NAME

acctcon, acctcon1, acctcon2 - connect-time accounting

SYNOPSIS

/usr/lib/acct/acctcon [options]

/usr/lib/acct/acctcon1 [options]

/usr/lib/acct/acctcon2

DESCRIPTION

acctcon converts a sequence of login/logoff records to total accounting records (see the tacct format in acct(4)). login/logoff records are read from standard input. The file /var/adm/wtmp is usually the source of the login/logoff records, however, because it may contain corrupted records or system date changes, it should first be fixed using wtmpfix. The fixed version of file /var/adm/wtmp can then be redirected to acctcon. The tacct records are written to standard output. Here are the options for acctcon:

-l file   file is created to contain a summary of line usage
          showing line name, number of minutes used, percen-
          tage of total elapsed time used,  number  of  ses-
          sions  charged,  number  of  logins, and number of
          logoffs.  This file helps track line usage,  iden-
          tify  bad  lines,  and  find software and hardware
          oddities.  Hangup,  termination  of  login(1)  and
          termination  of the login shell each generate log-
          off records, so that  the  number  of  logoffs  is
          often  three to four times the number of sessions.
          See init(1M) and utmp(4).
-o file   file is filled with  an  overall  record  for  the
          accounting  period,  giving  starting time, ending
          time,  number  of  reboots,  and  number  of  date
          changes.

acctcon is a combination of the programs acctcon1 and acctcon2. acctcon1 converts login/logoff records, taken from the fixed /var/adm/wtmp file, to ASCII output. acctcon2 reads the ASCII records produced by acctcon1 and converts them to tacct records. acctcon1 can be used with the -l and -o options, described above, as well as with the following options:

-p Print input only, showing line name, login name, and time (in both numeric and date/time formats).

-t acctcon1 maintains a list of lines on which users are logged in. When it reaches the end of its input, it emits a session record for each line that still appears to be active. It normally assumes that its input is a current file, so that it uses the current time as the ending time for each session still in progress. The -t flag causes it to use, instead, the last time found in its input, thus assuring reasonable and repeatable numbers for non-current files.

EXAMPLES

The acctcon command is typically used as follows:

  acctcon -l lineuse -o reboots < tmpwtmp > ctacct

The acctcon1 and acctcon2 commands  are  typically  used  as
follows:
  acctcon1 -l lineuse -o reboots < tmpwtmp | sort +1n  +2  >
  ctmp
  acctcon2 < ctmp > ctacct

NOTES

The line usage report is confused by date changes. Use wtmpfix (see fwtmp(1M)), with the /var/adm/wtmp file as an argument, to correct this situation.
