Syslog (AlphaCom)

Syslog is a standard for forwarding log messages in an IP network. The term "syslog" is often used for both the actual syslogprotocol, as well as the application or library sending syslog messages.

The syslog is configured from AlphaWeb.

Facility value

The Facility value is a way of determining which process of the AlphaCom created the message. Since the Syslog protocol was originally written on BSD Unix, the Facilities reflect the names of Unix processes and Daemons:

• Local0: Debug log
• Local1: System log
• Local2: Call Statistics Log

Debug log

The Debug log contains the same information as transmitted on the TST console. On AMC systems the information was stored in a small error buffer which could be read by the "err" command from the TST console.

The Debug Log reports on three priority levels:

Local0:Warning

Warning – Information to the user. Often identical to texts sent to the log port

Local0:Error

Error – The software handles a problem by e.g. aborting an operation and returning to idle, but logs a message

Local0:Crit

Disaster – Exchange reset. The state of the exchange is so bad that the software does a controlled reset to restore normal operation.

System log

The System Log reports on one priority level: Local1:Notice

Statistics log

The Call Statistics Log reports on one priority level: Local2:Info
