Top Left Box: Displays, in real time, graph of your hardware resources.
Top Right Box: Displays the Tasks, average load, and the uptime
Bottom Box: Displays the processes ID, , the user account, how many resources it is consuming (CPU/MEM), how long its been running and where it can be located.
- PID: The process ID.
- USER: The username of the process owner or the user ID if the name can’t be determined.
- PRI: The kernels internal priority for the process, usually just its NI value plus twenty. Different for real-time processes.
- NI: The nice value of a process, from 19 (low priority) to -20 (high priority).
- VIRT: Size in memory of the total program size.

- SHR: The size of the process’s shared pages.
- S: The state of the process.
- S: for sleeping or idle
- R: for running
- D: for disk sleep, uninterruptible
- Z: for zombie, waiting for parent to read its exit status
- T: for traced or suspended
- W: for paging
- CPU%: The percentage of the CPU time that the process is currently using.
- MEM%: The percentage of memory the process is currently using
- TIME+: The time, measured in clock ticks that the process has spent in user and system time
- Command: Full path of the command.
