13.2 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. The UDP port that was assigned
to Syslog is 514.
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
13.2.1 Syslog Servers
Users can use the provided Syslog server (ACSyslog08.exe) or other third-party Syslog servers.
Examples of Syslog servers available as shareware on the Internet:
• Kiwi Enterprises: www.kiwisyslog.com/
• The US CMS Server: uscms.fnal.gov/hanlon/uscms_server/
• TriAction Software: www.triaction.nl/Products/SyslogDaemon.asp
• Netal SL4NT 2.1 Syslog Daemon: www.netal.com
A typical Syslog server application enables filtering of the messages according to priority, IP
sender address, time, date, etc.
13.2.2 Operation
The Syslog client, embedded in the MediaPack, sends error reports/events generated by the
MediaPack unit application to a Syslog server, using IP/UDP protocol.
¾ To activate the Syslog client on the MediaPack, take these 4 steps:
1. Set the parameter ‘EnableSyslog’ to 1 (refer to Table 5-29 on page 117).
2. Use the parameter ‘SyslogServerIP’ to define the IP address of the Syslog server you use
(refer to Table
5-29 on page 117).
3. To determine the Syslog logging level use the parameter ‘GWDebugLevel’ (refer to Table
5-5 on page 67).
4.
To view changes made on-the-fly to parameters via Web or SNMP set the parameter
‘EnableParametersMonitoring’ to 1 (refer to Table
5-37 on page 128).
