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 ]
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 ...
RELP is inspired by RFC 3195 syslog and RFC 3080. During initial connection, sender and receiver negotiate session options, like supported command set or application level window size. Network event messages are transferred as commands, where the receiver acknowledges each command as soon as it has processed it.

Xerox Network Systems (XNS) Clearinghouse (Name Server). Despite this port being assigned by IANA, the service is meant to work on SPP (ancestor of IPX/SPX), instead of TCP/IP. [36] 55: Assigned: isi-gl (ISI Graphics Language) [3] 56: Assigned: Xerox Network Systems (XNS) Authentication Protocol.
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 ...
In computer log management and intelligence, log analysis (or system and network log analysis) is an art and science seeking to make sense of computer-generated records (also called log or audit trail records). The process of creating such records is called data logging. Typical reasons why people perform log analysis are:
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 ...
