Connect accounting enables you to determine the following:
The length of time a user was logged in
How the tty lines are being used
The number of reboots on your system
The frequency with which the accounting software was turned off and on
To provide this information, the system stores records of time adjustments, boot times, times the accounting software was turned off and on, 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 the /var/adm/wtmpx file. Entries in the wtmpx file 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.
