I mentioned Glances in my article 4 open source tools for Linux system monitoring, but I will delve into it more deeply in this article. However, Glances also monitors filesystem I/O, network I/O, and sensor readouts that can display CPU and other hardware temperatures as well as fan speeds and disk usage by hardware device and logical volume. All of these tools monitor CPU and memory usage, and most of them list information about running processes (at the very least). A few years ago, I found Glances, a tool that displays information that none of my other favorites do. ![]() For me, these primarily used to be top, atop, and htop. That’s all! If you have any questions or additional information to add, use the comment form below.Sysadmins have many tools to view and manage running processes. You can learn how to create new systemd services from this guide: How to Create Systemd Unit File in Linux One downside of running glances in web server mode is that, if the Internet connection is poor the client tends to easily disconnect from the server. You can change the refresh rate of the page, simply add the period in seconds at the end of the URL, this sets the refresh rate to 8 seconds. Monitor Remote Linux Server Under Glances Monitor Remote Linux Processes Under Glances $ sudo systemctl status rviceįinally, from your web browser, use the URL to remotely monitor your Linux servers via the glances UI, on any device (smartphone, tablet, or computer). Next, enable your new systemd service, start and view its status as follows. Disabling it will delete this symbolic link. Therefore, when you enable it, a symbolic link is created from the /etc/systemd/system//rvice to /usr/lib/systemd/system/rvice. The section informs systemd that this service is wanted by “ multi-user.target”. The -t specifies an interval for live updates in seconds. The above configuration tells systemd that this is a unit-of-type service, it should be loaded after the network.target.Īnd once the system is in the network target, systemd will invoke the command “ /usr/bin/glances -w -t 5” as a service. Then copy and paste the unit file configuration below in it. Start by creating your service unit file (which I have preferred to name as rvice) under /usr/lib/systemd/system/rvice. Run Glances in Web Server Mode as a Service I actually prefer this method to run it as a background process. If you are using the systemd system and services manager, you can run glances in web server mode as a service for efficient management, as explained in the next section. $ sudo ufw allow 61208/tcpĪfter that, from a web browser, use the URL to access the glances UI. $ sudo firewall-cmd -permanent -add-port=61208/tcpįor the UFW firewall, run these commands. ![]() If you are running firewalld services, then you should open port 61208 to allow inbound traffic to that port. By default, it will listen on port 61208. Once you have installed the above packages, launch glances with the -w flag to run it in web server mode. $ sudo zypper install glances python-bottle Īlternatively, install it using the PIP command shown. $ sudo emerge -a sys-apps/glances python-bottle $ sudo yum install glances python-bottle $ sudo apt install glances python-bottle To run glances in web server mode, you need to install it together with the Python bottle module, a fast, simple, and lightweight WSGI micro web-framework, using the appropriate command for your Linux distribution. Glances is a free open source, modern, cross-platform, real-time top and htop-like system monitoring tool, which offers advanced features compared to its counterparts, and can run in different modes: as a standalone, in client/server mode, and in web server mode.Ĭonsidering the web server mode, you do not necessarily need to log into your remote server via SSH to run glances, you can run it in web server mode and access it via a web browser to remotely monitor your Linux server, as explained below.
