This project provides a Tcl interface to the standard *nix syslog service. It implements a Tcl package that exports the full functionality of the underlying syslog facility to the Tcl programming language. This includes local and remote logging. Syslog is a standard for forwarding log messages in an IP network. It is also used to refer to the implementation of this standard and API, that supports both remote and local logging. It is typically used for computer system management and security auditing; usually to aggregate log messages in a central repository. It is standardized within the Syslog working group of the IETF. Syslog is available in all POSIX compliant and POSIX−like Operating Systems. ident is a optional string argument that is used by syslog to differentiate between processes and log contexts. It is up to the user to specify any Tcl string here. facility is an optional string dictated by syslog, and categorizes the entity that logs the message, in the following categories/facilities: Facility Description auth security/authorization messages authpriv security/authorization messages (private) cron clock daemon (cron and at) daemon system daemons without separate facility value ftp ftp daemon kern kernel messages local[0−7] local0 to local7 are reserved for local use lrp line printer subsystem mail mail subsystem news USENET news subsystem syslog messages generated internally by syslogd(8) user generic user−level messages uucp UUCP subsystem The default facility is "user". priority is another string dictated by syslog, that describes the severity of the message. In order of higher to lower severity, the possible strings are: Priority Description emergency system is unusable alert action must be taken immediately critical critical conditions error error conditions warning warning conditions notice normal, but significant, condition info informational message debug debug−level message This argument is mandatory. |
