locations. The available facility numbers are: Local 0 through Local 7. The
administrator of your syslog server should assign you a facility number.
For this example, the syslog system administrator sets up a server called
“syslogger” to handle log messages from two OnSites. One OnSite is located
in São Paulo, Brazil, and the other OnSite is in Fremont, California. The
syslog server’s administrator wants to aggregate messages from the São Paulo
OnSite into the
local1 facility, and to aggregate messages from Fremont
OnSite into the
local2 facility.
On “syslogger” the system administrator has configured the system logging
utility to write messages from the
local1 facility to the /var/log/
saopaulo-config
file and the messages from the local2 facility to the /
var/log/fremont-config
file. If you were in Fremont and identifying the
syslog server using the Web Manager, according to this example, you would
select the facility number Local 2 from the Facility Number pull-down menu
on the Syslog screen (under Configuration>Network>Syslog in Expert mode).
OnSite System Logging Options
The OnSite includes syslog-ng, which can be configured through either the
Web Manager or the CLI utility to filter messages from the following sources:
• Devices connected to serial (CAS) and AUX ports
• Devices connected to KVM ports
• Buffered data
•Web logs

Syslog messages can be sent to the following destinations:

OnSite Alarm Notifications
The OnSite administrator can configure the OnSite to send alarm notifications
about events detected in messages sent by devices connected to serial ports.
For sending alarms generated from devices connected to serial ports,
