Th two fields are separated by one or more spaces or tabs. The selector field specifies a pattern of facilities and priorities belonging to the specified action. +.SH SELECTORS + +The selector field itself again consists of two parts, a facility and a +priority, separated by a period ('.'). Both parts are case insensitive and can +also be specified as decimal numbers, but don't do that, you have been warned. +Both facilities and priorities are described in rsyslog(3). The names mentioned +below correspond to the similar LOG_-values in /usr/include/rsyslog.h. + +The facility is one of the following keywords: auth, authpriv, cron, daemon, +kern, lpr, mail, mark, news, security (same as auth), syslog, user, uucp and +local0 through local7. The keyword security should not be used anymore and mark +is only for internal use and therefore should not be used in applications. +Anyway, you may want to specify and redirect these messages here. The facility +specifies the subsystem that produced the message, i.e. all mail programs log +with the mail facility (LOG_MAIL) if they log using syslog. + +The priority is one of the following keywords, in ascending order: debug, info, +notice, warning, warn (same as warning), err, error (same as err), crit, alert, +emerg, panic (same as emerg). The keywords error, warn and panic are deprecated +and should not be used anymore. The priority defines the severity of the message. + +The behavior of the original BSD syslogd is that all messages of the specified +priority and higher are logged according to the given action. Rsyslogd behaves +the same, but has some extensions. + +In addition to the above mentioned names the rsyslogd(8) understands the +following extensions: An asterisk ('*') stands for all facilities or all +priorities, depending on where it is used (before or after the period). The +keyword none stands for no priority of the given facility. + +You can specify multiple facilities with the same priority pattern in one +statement using the comma (',') operator. You may specify as much facilities as +you want. Remember that only the facility part from such a statement is taken, a +priority part would be skipped. + +Multiple selectors may be specified for a single action using the semicolon +(';') separator. Remember that each selector in the selector field is capable +to overwrite the preceding ones. Using this behavior you can exclude some +priorities from the pattern. + +Rsyslogd has a syntax extension to the original BSD source, that makes its use +more intuitively. You may precede every priority with an equation sign ('=') to +specify only this single priority and not any of the above. You may also (both +is valid, too) precede the priority with an exclamation mark ('!') to ignore +all that priorities, either exact this one or this and any higher priority. If +you use both extensions than the exclamation mark must occur before the equation +sign, just use it intuitively. + .SH ACTIONS The action field of a rule describes what to do with the message.
