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, [2] support for different module outputs, [3] flexible configuration options and adds features such as using ...
strace is a diagnostic, debugging and instructional userspace utility for Linux.It is used to monitor and tamper with interactions between processes and the Linux kernel, which include system calls, signal deliveries, and changes of process state.
The Linux Trace Toolkit (LTT) is a set of tools that is designed to log program execution details from a patched Linux kernel and then perform various analyses on them, using console-based and graphical tools. LTT has been mostly superseded by its successor LTTng (Linux Trace Toolkit Next Generation).
Most implementations provide a command line utility, often called logger, as well as a software library, to send messages to the log. [14] 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 ...
Snare agents are also able to push logs over a unidirectional network in order to facilitate log transfer from networks of low classification to networks of higher classification. The Snare Server is an appliance, or software-only solution, that provides a variety of analysis tools and to facilitate the collection, analysis, reporting, and ...
systemd is a software suite that provides an array of system components for Linux [7] operating systems. The main aim is to unify service configuration and behavior across Linux distributions. [8] Its primary component is a "system and service manager" — an init system used to bootstrap user space and manage user processes.
Tracing in software engineering refers to the process of capturing and recording information about the execution of a software program. This information is typically used by programmers for debugging purposes, and additionally, depending on the type and detail of information contained in a trace log, by experienced system administrators or technical-support personnel and by software monitoring ...
Plan 9's Fossil file system is also log-structured and supports snapshots. NILFS is a log-structured file system implementation for Linux by NTT/Verio which supports snapshots. LinLogFS (formerly dtfs) and LFS are log-structured file system implementations for Linux. The latter was part of Google Summer of Code 2005. Both projects have been ...
