syslog vs rsyslog

With the rapid development of information technology, more and more devices in the network, and gradually we found that relying on traditional means to a table analysis equipment (routers, switches, firewalls, servers, databases, middleware, etc.) logs have seriously affected our work efficiency, and not the availability of business systems to provide protection. Always play the role of a fireman after a problem arises. Therefore, it is time for the operation of the log to centrally manage. Key

Syslog configuration log server on For large-scale network applications or applications with certain security requirements, you usually need to classify and review system logs. By default, each system records its own logs on the local hard disk. Although logs can also be recorded, there are many disadvantages: first, management is inconvenient. When the number of servers is large, it is very inconvenient to log on to each server to manage and analyze

Log4j supports syslog, but there are many deficiencies, so it needs to be modified. 1. When log4j supports syslog, the default size of the same MSG is 1024, which is also the rfc00004 standard of syslog. However, for more than 1024 MSG in actual applications, we still In the hope that the log can be completed completely, log4j will unpack MSG greater than 1024.
