Connect accounting enables you to determine how long a user was logged in and to obtain information about the usage of tty lines, the number of reboots on your system, and the frequency of the stopping and starting of the accounting software. To obtain this information, the system stores records of time adjustments, boot times, the turning on or off of the accounting software, changes in run levels, the creation of user processes, login processes, and init processes, and the deaths of processes. These records (produced from the output of system programs such as date, init, login, ttymon, and acctwtmp) are stored in /var/adm/wtmp. Entries in the wtmp directory may contain the following information: a user's login name, a device name, a process ID, the type of entry, and a time stamp denoting when the entry was made.
