If you are not running accounting, then you will have a hard time figuring out what processes were running - even if you do have accounting it may be difficult.

You can check out some of the following which may show some information.

last - you can tell who physcially signed into the system (by account) but not what they ran.
syslog - check if syslogd is running on server - then check /etc/syslog.conf to see where it's placing it's information - one file it may put it in is the /var/adm/messages file - this will contain errors/warnings/info

/var/adm/sa/* - you may or may not have files in this directory if sar is running - will give performance of server but not processes running.

If you give more information on what you are looking for, it may be easier for us to point you in the right direction.

Historical Disk bandwidth utilization

Early this morning our sar reports show that WIO on the system was over 50% for about an hour. We also had some users complain about response time problems during this time. Is there a way I can go back and check what disks were busy during this time (something like topas but for historical data)? (1 Reply)

reboot(8)						      System Manager's Manual							 reboot(8)

NAME
reboot - Restarts the machine SYNOPSIS
/usr/sbin/reboot [-dlnq] DESCRIPTION
When the system is running and multiple users are logged in, use the shutdown -r command to perform a reboot operation. If no users are logged in, use the reboot command. The reboot command normally stops all running processes, syncs the disks, logs the reboot, and writes a shutdown entry in the login accounting file, /var/adm/wtmp. The reboot command uses the sync call to synchronize the disks, and to perform other shutdown activities such as resynchronizing the hard- ware time-of-day clock. After these activities, the system reboots. By default, the system starts and the file systems are automatically checked. If the start-up activities are successful, the system comes up in the default run-level. You must have root privileges to use this command. Using the -n flag can result in file system damage. FLAGS
Generates a crash dump of the system before halting it. Can be used with any of the other flags. Does not log the reboot using syslog Does not sync the disks or log the reboot using syslog Performs a quick reboot without first shutting down running processes; does not log the reboot using syslog EXAMPLES
To enable the default reboot action, enter: reboot This command causes the system to stop all running processes, sync the disks, log the shutdown, and perform other routine shutdown and reboot activities. To shut down the system without logging the reboot, enter: reboot -l This command shuts down the system and performs all shutdown and reboot activities, except logging the shutdown. To reboot the system abruptly, enter: reboot -q This command reboots the system abruptly without shutting down running processes. FILES
