Syslog System Log Application1) OverviewSyslog is the default log daemon for Linux systems. The default syslog configuration file is the/etc/syslog.conf file. Programs, daemons, and kernels provide log information for accessing the system. Therefore, any program that wants to generate log information can generate this information to a syslog interface call.Almost

How to Use syslog-ng to collect logs from a remote Linux machine If your data centers are all Linux servers, you are the system administrator. One of your tasks is to view the server's log files. However, if you view log files on a large number of machines, You need to log in to the machine one by one to read the log files. If you manage a large number of machines, it will take you a day to work. In addition, you can configure a separate Linux machine
