ACCTCON(8) System Manager's Manual ACCTCON(8)
acctcon1, acctcon2 - connect-time accounting
/usr/lib/acct/acctcon1 [ -pt ] [ -l file ] [ -o file ]
acctcon1 converts a sequence of login/logoff records read from its
standard input to a sequence of records, one per login session. Its
input should normally be redirected from /var/adm/wtmp. Its output is
ASCII, giving device, user ID, login name, prime connect time (sec-
onds), non-prime connect time (seconds), session starting time
(numeric), and starting date and time.
acctcon2 expects as input a sequence of login session records and con-
verts them into total accounting records (see tacct format in acct(5)).
-p Print input only, showing line name, login name, and time (in
both numeric and date/time formats).
-t Test mode. 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.
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. Hang-up, termi-
nation of login(1) and termination of the login shell each gen-
erate logoff records, so that the number of logoffs is often
three to four times the number of sessions. See init(8) and
file is filled with an overall record for the accounting period,
giving starting time, ending time, number of reboots, and number
of date changes.
These commands are typically used as shown below. The file ctmp is
created only for the use of acctprc(8) commands:
acctcon1 -t -l lineuse -o reboots <<wtmp | sort +1n +2 >>ctmp
acctcon2 <<ctmp | acctmerg >>ctacct
acctcom(1), login(1), acct(2V), acct(5), utmp(5V), acct(8), acctcms(8),
acctmerg(8), acctprc(8), acctsh(8), fwtmp(8), init(8), runacct(8)
The line usage report is confused by date changes. Use wtmpfix (see
fwtmp(8)) to correct this situation.
