Linux Small Knowledge Translation-"syslog"

This conversation "syslog".

Last time I talked about "log" (LGO). This time the syslog, see log (logs) to understand what is going on. Syslog is the tool that gets the system log.

Many Uinix systems use this program, which takes on the important task of "getting all the logs of the system" to keep the system running.

The main body of the syslog is "syslogd", which is the daemon (generally translated into daemons), and the log is retrieved from the resident memory.

Syslog is characterized by the configuration file "/etc/syslog.conf", to "What kind of application?" What kind of information is important? Which file is recorded in? "etc. for meticulous configuration.

The last time I mentioned a little bit, a lot of logs make it difficult for administrators to see, and syslog can configure "get detailed logs only for programs that you want to pay special attention to".

In addition, Syslog has a non-known feature, that is, "you can transfer logs between the network and other hosts." The use of SSL and the like can achieve the encryption of the log transfer, you can do all the logs on the same server to manage.

A log is something that is essential to the system's ease of use, and Syslog is a powerful tool for getting logs. So be sure to use it skillfully.
