Htop is an interactive process viewer
First piece
1: First CPU Utilization 2:Second CPU Usage3:Third CPU Usage4:Fourth CPU UtilizationMem: Memory usage swap: Swap space usage second block
Tasks: Total number of processesNumber of Threads Load Average:1min5minaverage load before 15minUptime: Third block of system boot time?
PID: Process ID
User: The owner of the process PRI: Priority Ni:nice is used to adjust the user priority, the smaller the -20~19,nice priority, the higher the root user can increase the priority (Nice reduction), the average user can only lower the priority (Nice increase) VIRT (virtual Storage usage): Virtual memory res (resident): Resident memory shr: Shared memory S (state): Running status of the process
S: Sleeping (Idle) R: Running D: disk Sleep (uninterruptible) Z:Zombie (Waiting for parent to read it's exit status)
T:traced or suspended (e.g by SIGTSTP)
W:Paging
CPU%:CPU usage mem%: Memory usage time+: Program from power-on to now CPU-intensive command: program name and parameter fourth block
F1: Getting HelpP: Sort by CPU occupancy percentage
M: Sort by memory consumption percentage
T: Sort by consuming CPU Shichanglai
arrows: By the left and right arrows to move, you can also select by the mouse F2: Htop interface and display some special custom F3: Query F4: Filter F5: Display F6 as a process tree: Sort option F7:nice value priority increased, value decreased F8:nice value priority decreased, value increased F9: End process F10: Exit
