Concepts and FeaturesHistory log, historical events: Time, event itself, log level (depending on the criticality of time)System Log service: Syslog has two processes syslogd (System is responsible for user processes), KLOGD (kernel responsible for kernel processes)CENTOS7:RSYSLOG:SYSLOGD, KLOGDComparison of Rsyslog and syslog:1 , multi-process, can receive logs for non-native processes;2, support udp\tcp\ssl\tls
This is my entire process of log analysis for haproxy in the unit.We have been in the maintenance ES cluster configuration, and did not put a set of processes including the collection end of the code, all their own once, and the online collection of logs when we generally use the logstash, but the industry many people say logstash whether it is performance and stability is not very good, The advantage of Logstash is the simple configuration, this time I chose the RsyslogToday this haproxy log, I
Set up Rsyslog log server in CentOS 6.7Preface:
With the increase of servers and network devices in the IDC room, log management and query have become a headache for system administrators.
System Administrators encounter the following common problems:
1. During routine maintenance, it is impossible to log on to every server and device to view logs;2. The storage space on network devices is limited, and logs with Too Long dates cannot be stored. system

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
Objectiversyslog System Log, called the syslog on the CentOS5, and on the CentOS6 called Rsyslog, called the enhanced version of the SYSLOG,CENTOS5 on the configuration file under/etc/syslog.conf, and CentOS6 under/etc/rsyslog.conf.The syslog default is to put our logs into files, users, log servers, pipelines.Rsyslog has one more avenue on the syslog basis, allowing logs to be placed in MySQL data.Where is rsyslo
In general, the client side of the log collection scheme needs to install an additional agent to collect logs, such as Logstash, Filebeat, and so on, and the additional program means that the environment is complex and the resource is occupied, is there a way to implement log collection without the need for an additional installation program? Rsyslog is the answer you're looking for!
Rsyslog

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.

Loganalyzer is a Web front-end for syslog logs and other network event data. It provides a simple view of the log, search, basic analysis, and some chart reporting capabilities. Data can be obtained from a database or a generic syslog text file, so Loganalyzer does not need to change the existing record schema. Based on the current log data, it can handle syslog log messages, Windows event log records, support troubleshooting, and enable users to quickly find the solution to

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
