System
The SYSLOG utility creates a log of messages reporting significant events
occurring on an IAD, and makes this log available to a remote computer. SYSLOG
originated in early UNIX systems, and is described in RFC 3164. This RFC
specifies 24 different possible 'facilities' (services or software processes) from
which messages can be sent, and 8 'severity' levels for each event, as shown in
the following tables. The facility number and the severity level are combined into a
single field, the PRI (priority) field, which is the first field in each message.
In this release of the SLC ConnectReach system, a subset of the facilities and
severities are implemented. There are two classes of facilities, typically reported
in one of two severity levels, as shown in the table that follows.
