When operating over a network, syslog uses a client-server architecture where the server listens on a well-known or registered port for protocol requests from clients. Historically the most common transport layer protocol for network logging has been User Datagram Protocol (UDP), with the server listening on port 514. [ 15 ]
syslog-ng is a free and open-source implementation of the syslog protocol for Unix and Unix-like systems. It extends the original syslogd model with content-based filtering, rich filtering capabilities, flexible configuration options and adds important features to syslog, like using TCP for transport.

The product does not rely on a software agent that must run on hosts it is monitoring, so that data can be pushed back to a central server. "Supported" means that an agent may be used, but is not mandatory. An SNMP daemon does not count as an agent. SNMP Able to retrieve and report on SNMP statistics. Syslog Able to receive and report on ...
The Snare agents have been designed to collect audit log data from a host system, and push the data as quickly as possible, to a central server (or servers), for archive, analysis, and reporting. The central server can be either a syslog server, a Snare Server appliance, or a custom application.
As RELP designer Rainer Gerhards explains, the lack of reliable transmission in industry-standard syslog was a core motivation to create RELP. [2] Originally, RFC 3195 syslog was considered to take up this part in rsyslog, but it suffered from high overhead and missing support for new IETF syslog standards (which have since been published as ...
Octopussy has the ability to monitor any device that supports the syslog protocol, such as servers, routers, switches, firewalls, load balancers, and its important applications and services. The main purpose of the software is to alert its administrators and users to different kinds of events, like system outages, attacks on systems or errors ...
A server log is a log file (or several files) automatically created and maintained by a server consisting of a list of activities it performed. A typical example is a web server log which maintains a history of page requests. The W3C maintains a standard format (the Common Log Format) for web server log files, but other proprietary formats ...
