acctcon, acctcon1, acctcon2 --
acctcon converts a sequence of login/logoff records to total
accounting records (see the tacct format in
acctcon reads login/logoff records from standard input.
/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
Here are the options for acctcon:
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
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.
is filled with an overall record for the accounting period,
giving starting time,
number of reboots,
and number of date changes.
acctcon is a combination of the programs acctcon1 and
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,
and time (in both numeric and date/time formats).
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.
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
with the /var/adm/wtmp
file as an argument, to correct this situation.
