The default output of the ps command contains four columns that provide the following information: The command returns a similar output: PID TTY TIME CMD The ps command without any options displays information about processes that are bound by the controlling terminal. This guide provides an introduction to the ps aux command with brief examples to help you interpret its output. Since the ps aux command displays an overview of all the processes that are running, it is a great tool to understand and troubleshoot the health and state of your Linux system. A process is associated with any program running on your system, and is used to manage and monitor a program’s memory usage, processor time, and I/O resources. This tool should be considered a must-have for any Linux sysadmin.The ps aux command is a tool to monitor processes running on your Linux system. With the help of nmon you can monitor your Linux systems in real time or collect data to be combed through at a later date. You’d be hard-pressed to find a simpler solution to a pressing need. Modify that to fit your needs and you have an easy solution for troubleshooting an issue occurring on your Linux data center machines. The above cron job will run every day at 11:30 AM. Now open crontab for editing with the command crontab -e and enter something like this: Save that file and give it executable permissions with the command chmod u+x nmon.sh. A simple solution for this would be to create a bash script (we’ll call it nmon.sh) that contained something like the following: You could even create a cron job to schedule a regular dump of nmon-collected data (which could be handy for troubleshooting an recurring issue). Open that file to view the collected data. To do this, you would issue the command:Īfter issuing the above command you will find a file in the current working directory with the extension. Say you want to collect thirty rounds of information every 60 seconds. This can come in very handy if you need to monitor a system for a set period of time and then review the collected data later. The tool also includes the ability to capture information and save it to a file. To quit nmon, hit the q key and you will be returned to your bash prompt. By hitting the – key on your keyboard you will speed up the screen updates and, conversely, the + key will slow them down. The tool also includes the ability to increase and decrease the speed of updates. You can toggle any of the added statistics off by hitting the associated keyboard key (the same used to add). The resulting window will add those real-time statistics to the mix ( Figure C). Next we’ll add network and memory to the mix by hitting the n key followed by the m key (on your keyboard). If you hit the d key on your keyboard, nmon will display real-time statistics about any and all attached disks ( Figure B). Say you want to view information about disks. In the nmon window ( Figure A), you simply have to toggle the statistic(s) you want to view. Now that nmon is installed, you can fire it up by issuing the command nmon.

Install nmon with the command dnf install nmon.

Issue the command dnf install epel-release.

If you’re using a distribution that uses dnf (Redhat, Fedora, CentOS, etc.), the following steps will install nmon:

#Fedora process monitor software#

Install the software with the command sudo apt-get install nmon.For a distribution that uses apt (Debian, Ubuntu, etc.), do the following: This means you should be able to install nmon without too much fuss. The nmon application can be installed from your distribution’s standard repository. Let’s install nmon and see how it is used. And since it’s text-based, you can secure shell into your servers and get a quick glimpse from anywhere (as long as “anywhere” has access to said server). What’s best is that you get to choose what nmon displays. The nmon tool will, using a simple ncurses interface, display the usage for CPU, memory, network, disks, file system, NFS, top processes, resources, and power micro-partition.
