Cara Install Dan Monitoring Sistem GNU/Linux Ubuntu Menggunakan HTOP

HTOP merupakan aplikasi yang berfungsi untuk melihat proses yang terjadi pada sistem (desktop maupun server) secara realime. Aplikasi ini (HTOP) dikembangkan oleh Hisham Muhammad, pembaca bisa menghubunginya di alamat (sumber). Aplikasi ini bisa berjalan di sistem operasi GNU/Linux padaumumnya seperti Debian, CentOS, Fedora, dan Ubuntu yang kita bahas kali ini. Aplikasi ini bersifal GPL sehingga kita  bisa melihat sumbore kode (source code) dan ikut mengembangkannya jika mampu hihi. HTOP memiliki fungsi yang mirip dengan TOP, namun dengan menggunakan HTOP kita bisa me-scroll secara vertikal dan horizontal untuk melihat keseluruhan proses yang berjalan pada sistem.

Cara Menggunakan HTOP

Untuk menggunakan HTOP kita tinggal mengetik htop di terminal (jika sudah menginstallnya), kemudian untuk melihat kombinasi perintah apa saja yang terdapat di HTOP kita tinggal mengetik
man htop
Berikut kombinasi yang bisa kita gunakan untuk memonitoring sistem kita.


Mandatory arguments to long options are mandatory for short options too.
-d --delay=DELAY
Delay between updates, in tenths of seconds
-C --no-color --no-colour
Start htop in monochrome mode
-h --help
Display a help message and exit
-p --pid=PID,PID...
Show only the given PIDs
-s --sort-key COLUMN
Sort by this column (use --sort-key help for a column list)
-u --user=USERNAME
Show only the processes of a given user
-v --version
Output version information and exit


The following commands are supported while in htop:
Arrows, PgUP, PgDn, Home, End
Scroll the process list.
Tag or untag a process. Commands that can operate on multiple processes, like "kill", will then apply over the list of tagged processes, instead of the currently highlighted one.
Untag all processes (remove all tags added with the Space key).
Trace process system calls: if strace(1) is installed, pressing this key will attach it to the currently selected process, presenting a live update of system calls issued by the process.
Display open files for a process: if lsof(1) is installed, pressing this key will display the list of file descriptors opened by the process.
Trace process library calls: if ltrace(1) is installed, pressing this key will attach it to the currently selected process, presenting a live update of library calls issued by the process.
F1, h, ?
Go to the help screen
F2, S
Go to the setup screen, where you can configure the meters displayed at the top of the screen, set various display options, choose among color schemes, and select which columns are displayed, in which order.
F3, /
Incrementally search the command lines of all the displayed processes. The currently selected (highlighted) command will update as you type. While in search mode, pressing F3 will cycle through matching occurrences.
F4, \
Incremental process filtering: type in part of a process command line and only processes whose names match will be shown. To cancel filtering, enter the Filter option again and press Esc.
F5, t
Tree view: organize processes by parenthood, and layout the relations between them as a tree. Toggling the key will switch between tree and your previously selected sort view. Selecting a sort view will exit tree view.
On sorted view, select a field for sorting, also accessible through < and >. The current sort field is indicated by a highlight in the header. On tree view, expand or collapse the current subtree. A "+" indicator in the tree node indicates that it is collapsed.
F7, ]
Increase the selected process's priority (subtract from 'nice' value). This can only be done by the superuser.
F8, [
Decrease the selected process's priority (add to 'nice' value)
F9, k
"Kill" process: sends a signal which is selected in a menu, to one or a group of processes. If processes were tagged, sends the signal to all tagged processes. If none is tagged, sends to the currently selected process.
F10, q
Invert the sort order: if sort order is increasing, switch to decreasing, and vice-versa.
+, -
When in tree view mode, expand or collapse subtree. When a subtree is collapsed a "+" sign shows to the left of the process name.
a (on multiprocessor machines)
Set CPU affinity: mark which CPUs a process is allowed to use.
Show only processes owned by a specified user.
Sort by memory usage (top compatibility key).
Sort by processor usage (top compatibility key).
Sort by time (top compatibility key).
"Follow" process: if the sort order causes the currently selected process to move in the list, make the selection bar follow it. This is useful for monitoring a process: this way, you can keep a process always visible on screen. When a movement key is used, "follow" loses effect.
Hide kernel threads: prevent the threads belonging the kernel to be displayed in the process list. (This is a toggle key.)
Hide user threads: on systems that represent them differently than ordinary processes (such as recent NPTL-based systems), this can hide threads from userspace processes in the process list. (This is a toggle key.)
Refresh: redraw screen and recalculate values.
PID search: type in process ID and the selection highlight will be moved to it.


The following columns can display data about each process. A value of '-' in all the rows indicates that a column is unsupported on your system, or currently unimplemented in htop. The names below are the ones used in the "Available Columns" section of the setup screen. If a different name is shown in htop's main screen, it is shown below in parenthesis.


The full command line of the process (i.e program name and arguments).
The process ID.
The parent process ID.
The process's group ID.
The process's session ID.
The controlling terminal of the process.
The process ID of the foreground process group of the controlling terminal.


The state of the process:
for sleeping (idle)
for running
for disk sleep (uninterruptible)
for zombie (waiting for parent to read its exit status)
for traced or suspended (e.g by SIGTSTP)
for paging
The ID of the CPU the process last executed on.
The number of threads in the process.
The nice value of a process, from 19 (low priority) to -20 (high priority). A high value means the process is being nice, letting others have a higher relative priority. Only root can lower the value.
The percentage of the CPU time that the process is currently using.
The user CPU time, which is the amount of time the process has spent executing on the CPU in user mode (i.e everything but system calls), measured in clock ticks.
The system CPU time, which is the amount of time the kernel has spent executing system calls on behalf of the process, measured in clock ticks.
The time, measured in clock ticks that the process has spent in user and system time (see UTIME, STIME above).
The children's user CPU time, which is the amount of time the process's waited-for children have spent executing in user mode (see UTIME above).
The children's system CPU time, which is the amount of time the kernel has spent executing system calls on behalf of all the process's waited-for children (see STIME above).
The kernel's internal priority for the process, usually just its nice value plus twenty. Different for real-time processes.
The percentage of memory the process is currently using (based on the process's resident memory size, see M_RESIDENT below).
Size in memory of the total program size.
The resident set size, i.e the size of the text and data sections, plus stack usage.
The size of the process's shared pages
The size of the text segment of the process (i.e the size of the processes executable instructions).
The library size of the process.
The size of the data segment plus stack usage of the process.
The size of the dirty pages of the process.
The user ID of the process owner.
The username of the process owner, or the user ID if the name can't be determined.
The time the process was started.
The number of bytes the process has read.
The number of bytes the process has written.
The number of read(2) syscalls for the process.
The number of write(2) syscalls for the process.
Bytes of read(2) I/O for the process.
Bytes of write(2) I/O for the process.
The I/O rate of read(2) in bytes per second, for the process.
The I/O rate of write(2) in bytes per second, for the process.
The I/O rate, IO_READ_RATE + IO_WRITE_RATE (see above).
Bytes of cancelled write(2) I/O.
Which cgroup the process is in.

CTID OpenVZ container ID, a.k.a virtual environment ID.

OpenVZ process ID.
VServer process ID.
OOM killer score.

All other flags Currently unsupported (always displays '-'). (sumber)

Bagaimana, Anda tertarik untuk menginstall HTOP kedalam sistem operasi Anda??? Berikut, kita akan praktekkan Cara Install HTOP di GNU/Linux Ubuntu.

Cara Install HTOP

HTOP sudah terdaftar di repository, untuk menginstallnya kita bisa melalui Synaptic, Software Center atau terminal.
