The ‘htop’ Command<\/h3>\n
htop<\/code> is an interactive process viewer for Unix systems. It’s a great alternative to top<\/code> command. It provides a real-time, color-coded overview of running processes, and it allows you to scroll vertically and horizontally, so you can see all the processes running on the system, along with their full command lines.<\/p>\n
Here’s how to install htop<\/code>:<\/p>\n
# For Debian-based distributions\nsudo apt install htop\n\n# For RPM-based distributions\nsudo yum install htop\n\n# Output:\n# Loaded plugins: fastestmirror, langpacks\n# Loading mirror speeds from cached hostfile\n# Resolving Dependencies\n# --> Running transaction check\n# ---> Package htop.x86_64 0:2.3.0-8.el7 will be installed\n# --> Finished Dependency Resolution\n# Dependencies Resolved\n<\/code><\/pre>\n
And here’s a basic usage example:<\/p>\n
htop\n\n# Output:\n# 1  [||||||||||||||||||||||||||||100.0%]     Tasks: 31, 59 thr; 2 running\n# 2  [||||||||||||||||||||||||||||100.0%]     Load average: 0.01 0.02 0.05\n# Mem[|||||||||||||||387M\/1.94G]  Uptime: 00:04:05\n# Swp[|1M\/2.00G]\n<\/code><\/pre>\n
The ‘top’ Command<\/h3>\n
top<\/code> is a command that offers a dynamic real-time view of a running system. It displays system summary information as well as a list of tasks currently being managed by the Linux kernel. It’s less user-friendly than htop<\/code> but it’s installed by default on almost all Linux distributions.<\/p>\n
Here’s an example of how to use top<\/code>:<\/p>\n
top\n\n# Output:\n# top - 15:21:02 up  5:56,  1 user,  load average: 0.00, 0.01, 0.05\n# Tasks:  80 total,   1 running,  79 sleeping,   0 stopped,   0 zombie\n<\/code><\/pre>\n
The ‘glances’ Command<\/h3>\n
glances<\/code> is a cross-platform system monitoring tool written in Python. It uses the psutil library to get information from your system. It’s a bit more advanced than htop<\/code> and top<\/code>.<\/p>\n
Here’s how to install glances<\/code>:<\/p>\n
# For Debian-based distributions\nsudo apt install glances\n\n# For RPM-based distributions\nsudo yum install glances\n\n# Output:\n# Loaded plugins: fastestmirror, langpacks\n# Loading mirror speeds from cached hostfile\n# Resolving Dependencies\n# --> Running transaction check\n# ---> Package glances.noarch 0:3.1.7-1.el7 will be installed\n# --> Finished Dependency Resolution\n# Dependencies Resolved\n<\/code><\/pre>\n
And here’s a basic usage example:<\/p>\n
glances\n\n# Output:\n# Glances v3.1.7 with PsUtil v5.8.0\n# log file: \/tmp\/glances.log\n<\/code><\/pre>\n
Here’s a comparison of the key features of atop<\/code>, htop<\/code>, top<\/code>, and glances<\/code>:<\/p>\n\n\n\n\n\n\n\n\n
Tool<\/th>\nReal-time<\/th>\nInteractive<\/th>\nCross-platform<\/th>\nDefault Install<\/th>\n<\/tr>\n<\/thead>\n
