acctcon, acctcon1, acctcon2 -- connect-time accounting


/usr/lib/acct/acctcon [options]

/usr/lib/acct/acctcon1 [options]



acctcon converts a sequence of login/logoff records to total accounting records (see the tacct format in acct(4)). acctcon reads login/logoff records 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, percentage of total elapsed time used, number of sessions charged, number of logins, and number of logoffs. This file helps track line usage, identify bad lines, and find software and hardware oddities. Hangup, termination of login and termination of the login shell each generate logoff 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:

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

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.




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

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.
