The syslog daemon is configurable, which allows people to specify exactly a place of storage for each type of system information. Compared to syslog,

facilities can also be selected. note that this is only possible when using the name of the facilities. it is not possible to select ranges the numerical codes of the facilities. # Note: there is also a facility filter function that can be used to filter out specific faiclity. It also supports range filtering. # It is also filtered based on the internal number of facility.

First, Introduction Syslog is the default log daemon for Linux systems. The default primary and secondary configuration files are/etc/syslog.conf and/etc/sysconfig/syslog files, respectively. Normally, Syslog accepts information from various functions of the system, each of which includes important levels. The/etc/syslog.conf file notifies syslogd how to report i

For statistical convenience, we want to select some messages from the log and put them in the database. Read and write support for the database to add parameters at compile time, but also to open the corresponding module in the configuration file. Module if a lot of monitoring needs to the database module, can be placed in the/etc/rsyslog.conf global configuration file, if only a certain monitoring collection used to put in the corresponding local configuration file/etc/rsyslog.d/.

From the current situation, syslog (System log), a long-standing log system, still occupies the most mainstream status. Due to the origin of Unix-like platforms, Syslog is the most easily available log system in a real-world application environment. At the same time, there are many syslog-based extension products, including a large number of network hardware devi
