Syslog Support - 3Com V7122 User Manual

EnableDiagnostics is set to 2, flash is only partially tested. If an error is detected, an error
message is sent to the Syslog.
Run-time test (Periodic): Used for monitoring the gateway during run-time.
The Periodic Test is performed every hour after startup, even when there is full traffic on
the gateway; quality is not degraded. The following hardware components are being
tested:
TSA.
PSTN framers (when they are used).
Missing DSP's.
Conference channels (where they are supported).
If an error is detected, an error message is sent to the Syslog.
To continue regular operation, the Detailed test must be disabled. Set the
parameter EnableDiagnostics to 0 and reset the gateway.

Syslog Support

Syslog protocol is an event notification protocol that enables a machine to send event
notification messages across IP networks to event message collectors- also known as
Syslog servers. Syslog protocol is defined in the IETF RFC 3164 standard.
Since each process, application and operating system was written independently, there is
little uniformity to Syslog messages. For this reason, no assumption is made on the contents
of the messages other than the minimum requirements of its priority.
Syslog uses UDP as its underlying transport layer mechanism. By default, UDP port 514 is
assigned to Syslog, but this can be changed (using the SyslogServerPort parameter).
The Syslog message is transmitted as an ASCII (American Standard Code for Information
Interchange) 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 described above is known as the Priority and represents both the Facility and
Severity as described below. The Priority number consists of one, two, or three decimal
integers.
For example:
<37> Oct 11 16:00:15 mymachine su: 'su root' failed for lonvick on
/dev/pts/8
When NTP is enabled, a timestamp string [hour:minutes:seconds] is added to all
Syslog messages (for information on NTP, see
Support).
