How to track down a high server load RedHat/CentOS/Fedora/SuSe


Line 1 - General server information - Current time, uptime (since last restart of server), number of users logged on (other than yourself), and the load average for the last 1, 5, and 15 minutes
Line 2 - Tasks - Number of processes, number of actively running processes, sleeping process, stopped process, and zombie processes
Line 3 - CPU usage info (User, System, Nice, Idle, Waiting, Hardware Interrupts, Software Interrupts).  Just worry about Idle, user, system, and waiting.
Line 4 - Memory usage
Line 5 - Swap usage (used should be almost 0 if not 0)
Table header for process list (Process ID, User, Priority, Nice, Virtual Memory, Resident Size, Shared Size, , State, CPU, Memory, CPU Time used, Command)
The processes themselves
