To select all processes use the -A or -e option: Ps command will report a snapshot of the current processes. For a single CPU system 1 – 3 and SMP systems 6-10 load value might be acceptable. The load can change from system to system. The current time, how long the system has been running, how many users are currently logged on, and the system load averages for the past 1, 5, and 15 minutes. Uptime command can be used to see how long the server has been running. uptime – Tell how long the Linux system has been running w – Find out who is logged on and what they are doing w command displays information about the users currently on the machine, and their processes.
