Process management: top

- [Instructor] On a Linux system,…it's helpful to be able to see what processes are running…and how many resources they're using.…While we can look at the processes…and even find out some resource information…with the ps command,…there's another program called top…which gives us up to the second information…about resource usage.…I'll run the top command here,…and as you can see there's quite a bit of information…that it presents.…Here at the very top is the name of the program…followed by the server's local time…and then a listing of how long the system has been up,…that is how long since the last boot.…

After that comes a listing of how many user sessions…are active on the system,…and then a listing of the load average.…This shows how much work the processors…are being asked to do, over the past minute,…five minutes and 15 minutes.…On the next line we see some information…about running tasks or processes.…Right now there's 169 total here for me,…one of them's running and 168 of them are sleeping…which means they're loaded and have resources…
