Syslog and Debug Recordings
Syslog is an event notification protocol that enables a device to send event notification
messages across IP networks to event message collectors, also known as Syslog servers.
The device contains an embedded Syslog client, which sends error reports / events that it
generates to a remote Syslog server using the IP / UDP protocol. This information is a
collection of error, warning, and system messages that records every internal operation of
the device.
For receiving Syslog messages generated by the device, you can use any of the following
Syslog servers:
Device's embedded Syslog server:
The device provides an embedded Syslog
server, which is accessed through the Web interface. This provides limited Syslog
server functionality.
Wireshark:
Third-party network protocol analyzer (http://www.wireshark.org).
Third-party, Syslog server:
Any third-party Syslog server program that enables
filtering of messages according to parameters such as priority, IP sender address,
time, and date.
37.1 Syslog Message Format
The Syslog message is sent from the device to a Syslog server as an ASCII (American
Standard Code for Information Interchange) message. Syslog uses UDP as its underlying
transport layer mechanism. By default, UDP port 514 is assigned to Syslog, but this can be
changed (see 'Configuring Syslog' on page
383
).
Below is an example of a Syslog message:
13:10:57.811 : 10.13.4.12 : NOTICE :
[S=
235]
[SID:
1034099026] (
lgr_flow)(63 ) UdpTransportObject#0- Adding socket event
for address 10.33.2.42:5060

Description
Message Types
Syslog generates the following types of messages:
ERROR: Indicates that a problem has been identified that
requires immediate handling.
WARNING: Indicates an error that might occur if measures are
not taken to prevent it.
NOTICE: Indicates that an unusual event has occurred.
INFO: Indicates an operational message.
DEBUG: Messages used for debugging.
Notes:
The INFO and DEBUG messages are required only for advanced
debugging. Therefore, by default, they are not sent by the device.
When viewing Syslog messages in the Web interface, these
message types are color coded.
Message Sequence Number
[S=<number>]
Syslog messages are sequentially numbered in the format
[S=<
number>], for example, "
[S=
643]".
A skip in the number sequence of messages indicates a loss of
message packets. For example, in the below Syslog message
generation, messages 238 through 300 were not received. In other
words, three Syslog messages were lost (the sequential numbers
are indicated below in bold font):
