Syslog Server A syslog server is a system on the network (typically a UNIX system) that can receive and log syslog messages from other devices on the network. Syslog messages allow administrators to monitor status or troubleshoot network devices. A syslog server requires software that provides syslog capabilities running on the server. UNIX systems provide a daemon, syslogd, that monitors User Datagram Protocol (UDP) port 514 for incoming messages. The messages are processed depending on their priority and on how syslogd is set up to operate. You can configure the HP Jetdirect print server with the syslog server's IP address. When a syslog server is configured, both the HP Jetdirect print server and attached device can send syslog messages using UDP. The syslog server may not receive all syslog events from the HP Jetdirect print server: ■ UDP does not guarantee delivery of messages. ■ The HP Jetdirect print server attempts to eliminate duplicate messages (to minimize unnecessary network traffic). ■ The volume of messages sent by the HP Jetdirect print server is configurable. Methods to configure HP Jetdirect syslog parameters include BOOTP, DHCP, Telnet, the embedded Web server, and management software. For selected printers, a menu accessed through the printer control panel provides limited syslog configuration. The syslog configuration command or parameter entries may vary depending on the method used. For more information, see the applicable sections in this guide. Selected syslog parameters on the HP Jetdirect print server are listed in Table A-4 HP Jetdirect Syslog Parameters.

Syslog Server
A syslog server is a system on the network (typically a UNIX system) that can receive and log syslog
messages from other devices on the network. Syslog messages allow administrators to monitor
status or troubleshoot network devices.
A syslog server requires software that provides syslog capabilities running on the server. UNIX
systems provide a daemon, syslogd, that monitors User Datagram Protocol (UDP) port 514 for
incoming messages. The messages are processed depending on their priority and on how syslogd is
set up to operate.
You can configure the HP Jetdirect print server with the syslog server's IP address. When a syslog
server is configured, both the HP Jetdirect print server and attached device can send syslog
messages using UDP.
The syslog server may not receive all syslog events from the HP Jetdirect print server:
■
UDP does not guarantee delivery of messages.
■
The HP Jetdirect print server attempts to eliminate duplicate messages (to minimize
unnecessary network traffic).
■
The volume of messages sent by the HP Jetdirect print server is configurable.
Methods to configure HP Jetdirect syslog parameters include BOOTP, DHCP, Telnet, the embedded
Web server, and management software. For selected printers, a menu accessed through the printer
control panel provides limited syslog configuration. The syslog configuration command or parameter
entries may vary depending on the method used. For more information, see the applicable sections
in this guide.

HP Jetdirect Syslog Parameters
Item
Description
Syslog Server IP address
IP address of a syslog server for sending syslog messages. If zero (0.0.0.0) or
not specified, syslog messages are disabled.
Syslog Maximum Messages
The number of syslog messages that can be sent by the HP Jetdirect print server
on a per-minute basis, from 0 to 1000. This parameter helps to control the syslog
file size. The default is 10 messages per minute. If 0, the number of syslog
messages is not restricted.
Syslog Priority
A method for filtering syslog messages that are sent to the syslog server. The
range is 0 through 8, with 0 the most specific and 8 the most general. Only
messages that are lower than the specified filter level (or higher in priority) are
reported. The default is 8, messages of all priorities are sent. If 0, all syslog
messages are disabled.
Syslog Facility
A code used to identify the source facility of a message (for example, to identify
the source of selected messages during troubleshooting). By default, the HP
Jetdirect print server uses LPR as the source facility code, but local user values
of local0 through local7 can be used to isolate individual or groups of print servers.
Typical logfile entries of syslog messages are illustrated below:
