![]() Nethogs has found its way by now into the official package repositories for more popular distributions. Also, Nethogs analyzes the network usage for a single system and doesn't attempt to study all the traffic on the network. ![]() Currently, Nethogs only shows you the TCP data flow other protocols, such as ICMP or UDP, are not supported. You will find the official source code at the project website. Nethogs, which is licensed under the GPL, relies on the virtual proc filesystem for the analysis (relying on /proc/net/tcp and /proc/net/tcp6, among others). A view of the network by process is particularly useful if you want to know which application is currently involved in a particularly intensive communication. Nethogs is a little-known utility that breaks down network bandwidth by process. However, unlike Containers, virtual machines run their own operating systems rather than sharing one operating system kernel.For more than 10 years, Arnout Engelen has worked on his Nethogs tool. Like a Container, a virtual machine is functionally identical to an isolated standalone computer, with its own IP addresses, processes, files, users database, configuration files, applications, system libraries, and so on. A virtual file system for legacy Containers. The subsystem of the Virtuozzo software for managing Container memory and some system-related resources. Application templates are used to install an application or a set of applications in Containers. OS Templates are used to create new Containers with a pre-installed operating system. A set of original application files (packages) repackaged for mounting. A part of the file system storing Container files that are not shared with other Containers. An operating system virtualization solution allowing you to create multiple isolated Containers on a single physical server to share hardware, licenses, and management effort with maximum efficiency. Parallels Virtuozzo Containers for Linux. By caching identical files in multiple Containers it helps save memory and IOPS on the Hardware Node. A license key for Virtuozzo Storage to use its functionality. Every physical server must have its own key installed. A license key that you should install on the physical server to use Virtuozzo. A server where the Virtuozzo software is installed for hosting Virtuozzo virtual machines and Containers. A template used to create new Containers with a pre-installed operating system. OS virtualization provides the necessary environment for creating and managing Virtuozzo Containers. A technology allowing you to virtualize physical servers at the operating system (kernel) level. Operating system virtualization (OS virtualization). Hardware virtualization provides the necessary environment for creating and managing Virtuozzo virtual machines. A technology allowing you to virtualize physical servers at the hardware level. It can be any of the supported Windows or Linux operating systems. An operating system installed inside a virtual machine and Container. A Container is a kind of ‘sandbox’ for processes and users. However, they are isolated from each other. Containers share one host and one OS kernel. A virtual private server, which is functionally identical to an isolated standalone server, with its own IP addresses, processes, files, users database, configuration files, applications, system libraries, and so on. See also Template.Ĭontainer (or regular Container). A template used to install a set of applications in Containers. References to terms defined elsewhere in the glossary appear in italics.Īpplication template. ![]() ![]() This glossary defines terms and spells out abbreviations used in Virtuozzo documentation.
