Notifications, Alarms, and Data Buffering
The administrator can configure system logging (syslogging), so that
messages about the OnSite, any connected IPDUs, computers, or other
connected devices can be sent to a syslog server for handling.
The administrator can also configure data buffering to store data from
communications on serial ports for possible monitoring. If data buffering is
enabled the administrator can also configure alarms and notifications so that
remote administrators may be alerted to problems as they occur and notified
about server performance, software and configuration changes on devices
connected to serial ports.
Data from communications with serial-connected consoles can be stored
(buffered) locally, in the OnSite’s flash memory, or remotely, either on an NFS
server or syslog server.
Syslog Servers
Messages about the OnSite, its connected IPDUs, and other connected devices
can be sent to central logging servers, called syslog servers. Console data
from devices connected to serial ports can be stored in data buffer files on
syslog servers. By default, logging and data buffering are not done.
Syslog servers run operating systems that support system logging services,
usually they are UNIX-based servers with the syslogd configured.
Prerequisites for Logging to Syslog Servers
Before configuring syslogging, the OnSite administrator must ensure that an
already-configured syslog server with a public IP address is accessible from
the OnSite. The OnSite administrator must be able to obtain the following
information from the syslog server’s administrator.
• The IP address of the syslog server
• The facility number for messages coming from the OnSite.
See the following background information about facility numbers, if needed.
Facility Numbers for Syslog Messages
Each syslog server has seven local facility numbers available for its
administrator to assign to different devices or groups of devices at different
