Rsyslog
Rsyslog is an open-source software utility used on UNIX and Unix-like computer systems for forwarding log messages in an IP network. It implements the basic syslog protocol, extends it with content-based filtering, rich filtering capabilities, queued operations to handle offline outputs, support for different module outputs, flexible configuration options and adds features such as using TCP for transport. The official RSYSLOG website defines the utility as "the rocket-fast system for log processing". Protocol Rsyslog uses the standard BSD syslog protocol, specified in RFC 3164. As the text of RFC 3164 is an informational description and not a standard, various incompatible extensions of it emerged. Rsyslog supports many of these extensions. The format of relayed messages can be customized. The most important extensions of the original protocol supported by rsyslog are: * ISO 8601 timestamp with millisecond granularity and time zone information * the addition of the name of ...

NXLog
NXLog is a multi-platform log collection and centralization tool that offers log processing features, including log enrichment (parsing, filtering, and conversion) and log forwarding. In concept NXLog is similar to syslog-ng or Rsyslog but it is not limited to UNIX and syslog only. It supports all major operating systems such as Windows, macOS, IBM AIX, etc, being compatible with many SIEM, log analytics suites and many other platforms. NXLog can handle different log sources and formats, so it can be used to implement a centralized, scalable logging system. ''NXLog Community Edition'' is proprietary and can be downloaded free of charge with no license costs or limitations. Overview 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.

Syslog
In computing, syslog is a standard for message logging. It allows separation of the software that generates messages, the system that stores them, and the software that reports and analyzes them. Each message is labeled with a facility code, indicating the type of system generating the message, and is assigned a severity level. Computer system designers may use syslog for system management and security auditing as well as general informational, analysis, and debugging messages. A wide variety of devices, such as printers, routers, and message receivers across many platforms use the syslog standard. This permits the consolidation of logging data from different types of systems in a central repository. Implementations of syslog exist for many operating systems. When operating over a network, syslog uses a client-server architecture where a syslog server listens for and logs messages coming from clients. History Syslog was developed in the 1980s by Eric Allman as part of the Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syslog-ng
syslog-ng is a free and open-source implementation of the syslog protocol for Unix and Unix-like systems.

System Administration
A system administrator, or sysadmin, or admin is a person who is responsible for the upkeep, configuration, and reliable operation of computer systems, especially multi-user computers, such as servers. The system administrator seeks to ensure that the uptime, performance, resources, and security of the computers they manage meet the needs of the users, without exceeding a set budget when doing so. To meet these needs, a system administrator may acquire, install, or upgrade computer components and software; provide routine automation; maintain security policies; troubleshoot; train or supervise staff; or offer technical support for projects. Related fields Many organizations staff offer jobs related to system administration. In a larger company, these may all be separate positions within a computer support or Information Services (IS) department. In a smaller group they may be shared by a few sysadmins, or even a single person. * A database administrator (DBA) maintains a ...

Internet Standards
In computer network engineering, an Internet Standard is a normative specification of a technology or methodology applicable to the Internet. Internet Standards are created and published by the Internet Engineering Task Force (IETF). They allow interoperation of hardware and software from different sources which allows internets to function. As the Internet became global, Internet Standards became the lingua franca of worldwide communications. Engineering contributions to the IETF start as an Internet Draft, may be promoted to a Request for Comments, and may eventually become an Internet Standard. An Internet Standard is characterized by technical maturity and usefulness. The IETF also defines a Proposed Standard as a less mature but stable and well-reviewed specification. A Draft Standard was an intermediate level, discontinued in 2011. A Draft Standard was an intermediary step that occurred after a Proposed Standard but prior to an Internet Standard. As put in RFC 2026: In ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internet Protocols
The Internet protocol suite, commonly known as TCP/IP, is a framework for organizing the set of communication protocols used in the Internet and similar computer networks according to functional criteria. The foundational protocols in the suite are the Transmission Control Protocol (TCP), the User Datagram Protocol (UDP), and the Internet Protocol (IP). In the development of this networking model, early versions of it were known as the Department of Defense (DoD) model because the research and development were funded by the United States Department of Defense through DARPA. The Internet protocol suite provides end-to-end data communication specifying how data should be packetized, addressed, transmitted, routed, and received. This functionality is organized into four abstraction layers, which classify all related protocols according to each protocol's scope of networking. An implementation of the layers for a particular application forms a protocol stack. From lowest to high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Journald
systemd is a software suite that provides an array of system components for Linux operating systems. Its main aim is to unify service configuration and behavior across Linux distributions; Its primary component is a "system and service manager"—an init system used to bootstrap user space and manage user processes. It also provides replacements for various daemons and utilities, including device management, login management, network connection management, and event logging. The name ''systemd'' adheres to the Unix convention of naming daemons by appending the letter ''d''. It also plays on the term "System D", which refers to a person's ability to adapt quickly and improvise to solve problems. Since 2015, the majority of Linux distributions have adopted systemd, having replaced other init systems such as SysV init. It has been praised by developers and users of distributions that adopted it for providing a stable, fast out-of-the-box solution for issues that had existed in ...
