I. Introduction of LoganalyzerThe Loganalyzer tool provides an easy-to-use, powerful front-end for searching, viewing and analyzing network activity data, including system logs, event logs, and many other log sources. Since it only presents the data to our users, the data itself needs to be collected by another program, such as Syslogd,rsyslog (which is now the default syslogd for the distribution), Winsyslog or Monitorware proxy. Loganalyzer is also
The importance of the system log, I believe we all have a deep understanding, when the failure, the first time is to look at the relevant error information and log information to locate the problem, can also be based on the log, log analysis, so as to obtain the system operation of some laws, this article on the system log on the first off content, specifically divided into:

(a) Rsyslog profileRyslog is a fast-track process for collecting system logs, providing high performance, security features, and modular design. Rsyslog is an upgraded version of Syslog that converts multiple source input and output conversions to destinations.Rsyslog is an open source tool that is widely used in Linux systems to forward or receive log messages through the TCP/UDP protocol. The
Rsyslog is a modular architecture used to record log files. Supports multiple protocols, such as TCP, SSL, TLS, and RELP. It also supports MySQL, pgsql, Oracle, and other relational data. Rsyslog is an enhanced version of syslog. We can use it to record local log files, or record logs of other clients on a server host.

As a system O M engineer, I think it is a daily task to view and analyze LINUX system logs. However, after a long time, I find that every time I view the site logs, I have to go to the background one by one, several servers can do this, but if you manage hundreds of thousands of online servers, this method is too slow.
Later I thought that I could not have a log server to manage logs in a centralized manner, and showed the logs to the front-end for easy viewing in the form of WEB. The idea of c

1. Brief Description
Logs record all operations on the server system. Therefore, managing server logs is a daily task of every O M personnel and an effective means to evaluate the security of servers, but how to manage the logs of many servers? If you want to watch it on one machine, you may be tired and tired.
Therefore, we need to build a log server and store all the server logs to this remote log server. In this way, we can not only centrally manage and evaluate the security status of each s
Rsyslog is a multi-thread enhanced version of syslogd. It expands many other functions based on syslog, such as database support (MySQL, PostgreSQL, Oracle, etc.), log content filtering, and log format template definition. In addition to the default UDP protocol, rsyslog also supports TCP to receive logs.This article only provides simple configuration and instructions. For more information about log-related
Use rsyslog to audit Linux Users
Rsyslog is part of the standard Linux system. It can write logs in real time and selectively Send Logs to remote log servers.
The dependency on. bash_history or script to audit the commands executed by the user is unreliable. Although both of them record user behavior, they may be tampered with by the user. Rsyslog can be used to

RSYSLOG is an efficient logging system and is the default journaling system currently used by Ubuntu and CentOS.Loganalyzer is a PHP-written Web front-end that you can use to analyze and view the logs generated by RSYSLOG.After research, I am prepared to use these two systems directly. This article has documented the problems I have encountered in configuring both systems.Introduction to Rsyslog Configurati
