Press F6 (or >), which will display the column names, select any one of the column, and press Enter. By default htop command displays the processes sorted by CPU usage. View. F6 or > → Select field for sorting. The top command is a great way to get a quick overview of how your system is performing and how apps are using your resources. By default, this is set to the PERCENT_CPU option. F6 Sort By can be used to sort the process via CPU usage and memory usage. Ok, so I am using the Top command on my linux VPS to try and see the processes using the most CPU %. To view the output options, simply hit the F6 function key on your keyboard. If you are unfamiliar with it, it’s basically a command line task manager like Activity Monitor and it shows processor usage, memory usage, disk activity, load average, and other helpful system resource details. The command usage is divided into three parts. Sort by processor usage (top compatibility key). Htop provides multiple options that you can use to sort your output. A load of 2.5 for example means that there are 2.5 instructions for every instruction the CPU can deal with in real time. 2) Iostat. Sort by memory usage (top compatibility key). F4 or I → Invert sort order. Zenith - sort of like top or htop but with zoom-able charts, CPU, GPU, network, and disk usage Topics cpu linux terminal-application process-monitor tui macos disk zenith MEM% – The percentage of Memory consumed by the process. htop supports mouse operation, uses color in its output and gives visual indications about processor, memory and swap usage. I'm not sure if this is a quirk of OS X or some other issue - you might want to check this with activity monitor The second part (upper-right corner) shows us standard information, such as a task summary, load average, and uptime. 1.0 INTRODUCTION. There are more process-related attributes. To sort with a new field, use the “up/down” arrow to select the correct selection, and then press “s” to sort it. Provided by: htop_2.2.0-2build1_amd64 NAME htop - interactive process viewer SYNOPSIS htop [-dChustv] DESCRIPTION Htop is a free (GPL) ncurses-based process viewer for Linux. I did not know that I could press ‘1’ to see cpu threads and always installed htop instead, which is also great. top sort by CPU in linux A leading ‘+’ will force sorting high to low, whereas a ‘-” will ensure a low to high ordering. Below this is the list of processes running on the system, sorted by CPU usage. Footer: The footer area has the htop menu option, which allows you to perform various actions immediately. P: Sort by processor usage (top compatibility key). In this tutorial we'll take a look at the most common uses of the top command, including showing how to sort the output by CPU and memory use, and change the top command display. Type the following command to install htop: ... Nice. htop is not available for Windows but there are plenty of alternatives that runs on Windows with similar functionality. The htop footer contains its menu command. Page Up and Page Down also work. ... but the htop utility functions similarly to top but it streamlines the display and ties behavior to real-time function key presses rather than a complex menu of letter-and-switch behavior. Install htop command. By default, it uses CPU% for sorting. K: Kill all tagged processes. You can scroll this list up and down and left and right (to see the full list of arguments for the processes) using the cursor keys. Press any key to return. Press h to start help. To install htop, sort the list of processes using criteria such as: CPU usage, memory, virtual memory, and others and then, search for a process. 'U' to view processes owned by a specific user. g: Go to the top of the process list. To sort them with respect to PID, users or any other parameter, press F6 which will show a number of parameters with which you can sort your processes. F5 or t → Tree view toggle. Zenith is a terminal monitor that looks sort of like top or htop but with zoom-able charts, CPU, GPU, network, and disk usage written in Rust. Optional CPU, Memory, Network, and Disk usage charts; Quick glances at Disk free space, NIC IP addresses, CPU frequency; Highlight top users of CPU, Memory, & Disk 4. In a nutshell, htop is a useful command-line tool in the Linux environment to determine the cause of load by each process. The processes enlisted when HTOP is run are sorted with respect to their CPU usage. The length of the queue determines the Load of the system. # htop. 'R' to renice processes. The Unix and Linux top command. u: Display all processes owned by a specific user; p: Sort processes based on high CPU consumption; m: Sort processes based on high memory consumption; t: sort process on time. To change the sort criteria, press “M” to sort by memory and “T” to sort by time. ... Htop. Command – The complete command for the process with program name and arguments; These are the standard columns for the htop command. However, since htop is a newer program compared to top, it offers many improvements. My Telnet-SSH screen is only about 60 rows high so the processes with the highest CPU % usage are at the bottom and I can't see them! Sorting output: Htop command provides multiple options to sort the output. Conclusion. CPU[||||| 63.2%] Tasks: 89, 114 thr; 1 running Mem[||||| 167/1001MB] Load average: 0.19 1.13 0.75 Swp[ 0/1021MB] Uptime: 00:06:54 for example. The program is bound via taskset -p 0x10 199042 to CPU core 5 (1.5% usage in pic below) Not matter in htop or ps -p 199042 -o %cpu, it shows about 8.1% CPU usage. htop is a powerful terminal-based system monitoring application that presents data of various system processes and their resource consumption in a human-readable, color-coded, easy-to-use format. U: Untag all tagged processes. htop is a small useful ncurses-based cli system monitoring program which lists the systems processes. Htop is a process viewer and a text-mode application for system monitoring in real-time like top. CPU% – The percentage of CPU used by the process. In the screenshot attached below, I sorted out according to memory utilization. These commands can be used to do various functions for e.g. Htop is a free (GPL) ncurses-based process viewer for Linux. I: Invert the sort order. /: Search processes; There are plenty of more options you that you can access through help or setup. CPU average is not the same as iowait. F "Follow" process: if the sort order causes the currently selected process to move in the list, make the selection bar follow it. Most of the peoples are familiar with the top command line utility to cross-verify the core information of CPU or memory, but htop linux command is smart alternative for top linux command. T: Sort by time (top compatibility key). – Dan Moulding Jan 15 at 4:09 The sort field is indicated by a highlight in the header. I hit the P to sort by CPU % but it wants to sort them from lowest to highest (ascending).
