Sample Daily Report
The from and to
lines tell you the time period reflected in the report:
the period from the time
the last accounting report was generated until
the time the current accounting report was generated.
It is followed by a log of system reboots, shutdowns,
power fail recoveries, and any other records dumped into
/var/adm/wtmp by the acctwtmp program. See
for more information.
The second part of the report is
a breakdown of line utilization.
The TOTAL DURATION
tells how long the system was in multiuser state
(accessible through the terminal lines).
The columns are:
During real time, monitor /var/adm/wtmp
because it is the file on which the connect accounting is based.
If the wtmp file grows rapidly, execute this command:
the terminal line or access port
the total number of minutes that line was in use
during the accounting period
the total number of
the line was in use,
divided into the
the number of times this port was accessed for a
This column does not have much meaning anymore.
It used to list the number of times a port
was used to log a user on, but because
login can no longer be executed
explicitly to log in a new user,
this column should be identical with
This column reflects not just the number of times a user logs
off but also any interrupts that occur on that line.
Generally, interrupts occur on a port
the first time ttymon is invoked after the system
has been brought to multiuser state. This column is significant
when the # OFF exceeds
the # ON by a large factor.
This usually means the multiplexor, modem,
or cable is going bad,
or there is a bad connection somewhere.
The most common cause of this is an
unconnected cable dangling from the multiplexor.
acctcon -l file < /var/adm/wtmp
You can see which tty line is the noisiest.
If the interrupting is occurring at a furious rate,
general system performance will be affected.
