Syslog Support

The Syslog protocol is an event notification protocol that allows a device to send event
notification messages across IP networks to event message collectors, also known as
Syslog servers. Since each process, application and operating system was written
somewhat independently, there is little uniformity to Syslog messages. For this
reason, no assumption is made regarding the contents of the messages other than the
minimum requirements of its priority.
Syslog uses UDP as its underlying transport layer mechanism. The UDP port
assigned to Syslog is 514. The Syslog message is transmitted as an ASCII message.
The message starts with a leading "<" ('less-than' character), followed by a number,
which is followed by a ">" ('greater-than' character). This is optionally followed by a
single ASCII space. The number is known as the Priority and represents both the
Facility and Severity as described in the Examples below.
The Avaya application performs as a Syslog client. Messages (currently Error Reports
events) generated by the Avaya application are sent via UDP and IP to a Syslog
server application.
Currently there are 5 error levels reported by the Syslog client Examples:
Emergency level message:
<128>sctp socket setsockopt error 0xf0 [File:sctp.cpp Line:453]
Warning level message
<132>Release contains no h.225 Reason neither q.931 Cause information
stateMode:1 [File: Line:-1];
Notice level message:
<133>(lgr_flow)(2546) | #0:ON_HOOK_EV
Info level message:
<134>document http://ab.pisem.net/RadAAIP.txt was not found in documents
table [File:vxml_handleDB.cpp Line:2348]
Debug level message:
<135>SCTP port 2905 was initialized [File:csAPI.cpp Line:150] [CID:0]

Gateway Faults and Alarm Monitoring

Gateway operations can be monitored in two different ways:
Running in idle mode awaiting for alarm traps - stimulus operation
Periodic polling for the MIB components - polling operation
This section describes the list of traps that the Media Gateway reports. It can be used
when working in stimulus operation mode.
