Docker is a set of platform as a service (PaaS) products that use OS-level virtualization to deliver software in packages called containers. [5] The service has both free and premium tiers. The software that hosts the containers is called Docker Engine. [6] It was first released in 2013 and is developed by Docker, Inc. [7]
Components of some Linux desktop environments that are daemons include D-Bus, NetworkManager (here called unetwork), PulseAudio (usound), and Avahi.. In multitasking computer operating systems, a daemon (/ ˈ d iː m ən / or / ˈ d eɪ m ən /) [1] is a computer program that runs as a background process, rather than being under the direct control of an interactive user.
NXLog can be installed on many operating systems and it is enabled to operate in a heterogeneous environment, collecting event logs from thousands of different sources in many formats. NXLog can accept event logs from TCP , UDP , [ 9 ] file, database and various other sources in different formats such as syslog , windows event log, etc. [ 10 ...
To display and monitor the collected logs one needs to use a client application or access the log file directly on the system. The basic command line tools are tail and grep . The log servers can be configured to send the logs over the network (in addition to the local files).
Alternatively, the messages may be written to a dedicated logging system or to a log management software, where it is stored in a database or on a different computer system. Specifically, a transaction log is a log of the communications between a system and the users of that system, [2] or a data collection method that automatically captures ...
Docker, Inc. is an American technology company that develops productivity tools built around Docker, which automates the deployment of code inside software containers. [1] [2] Major commercial products of the company are Docker Hub, a central repository of containers, and Docker Desktop, a GUI application for Windows and Mac to manage containers.
It provides operating system-level virtualization through a virtual environment that has its own process and network space, instead of creating a full-fledged virtual machine. LXC relies on the Linux kernel cgroups functionality [8] that was released in version 2.6.24. It also relies on other kinds of namespace isolation functionality, which ...
A log-structured filesystem is a file system in which data and metadata are written sequentially to a circular buffer, called a log.The design was first proposed in 1988 by John K. Ousterhout and Fred Douglis and first implemented in 1992 by Ousterhout and Mendel Rosenblum for the Unix-like Sprite distributed operating system.
