Tag: Host and priority definition establish record collection kernel www.Syslog is the default log daemon for Linux systems, and the default syslog configuration file is the/etc/syslog.conf file. The syslog daemon is configurable, which allows people to specify exactly a place of storage for each type of system information. Compared to syslog,

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.

We all know that logs are generated in the operating system to facilitate the Administrator to troubleshoot all aspects of the operating system. However, the default daily system logs do not classify the logs, so it is inconvenient to classify and troubleshoot the problems. Therefore, I have learned a lot about syslog. The following is a summary of the log classification configuration method. Syslog configu

The syslog mechanism is responsible for sending and recording the information generated by the system kernel and tools. It consists of the syslog () call, the syslogd daemon process, and the configuration file/etc/syslog. conf. When the system kernel and tool generate information, send the information to syslogd by calling sy
