This setting will send all events to remote Syslog systemĪ "panic" condition - notify all tech staff on call? (Earthquake? Tornado?) - affects multiple apps/servers/sites. Recommended practice is to use the Notice or Informational level for normal messages.Įxplanation of the severity Levels: SEVERITY LEVELĭefault SMS setting for Syslog Security option. Cisco routers for example use Local6 or Local7. Local0 through to Local7 are not used by UNIX and are traditionally used by networking equipment. If you are receiving messages from a UNIX system, it is suggested you use the “User” Facility as your first choice. Note: Items in yellow are the facility numbers available on the SMS. List of available Facilities as per RFC5424: Facility Number Since the Syslog protocol was originally written on BSD Unix, the Facilities reflect the names of UNIX processes and Daemons. The Facility value is a way of determining which process of the machine created the message. So by changing the facility number and/or the severity level you change the amount of alerts (messages) that are sent to the remote syslog server For example, is the event created by the kernel, by the mail system, by security/authorization processes, etc.? In the context of this field, the facility represents a kind of filter, instructing SMS to forward to the remote Syslog Server only those events whose facility matches the one defined in this field. The facility represents the machine process that created the syslog event. Also, a "local use 4" message (Facility=20) with a Severity of Notice (Severity=5) would have a Priority value of 165. For example, a kernel message (Facility=0) with a Severity of Emergency (Severity=0) would have a Priority value of 0. The priority value is calculated using the formula (Priority = Facility * 8 + Level). The priority is enclosed in "" delimiters. The priority value ranges from 0 to 191 and is not space or leading zero padded. When you create a new remote Syslog server, you have the option to exclude backlog events.Įach Syslog message includes a priority value at the beginning of the text. Through the SMS Admin interface, you can configure which events are sent to a remote Syslog server. SMS events can be directed to a remote Syslog server.
