BLACK BOX® CS Installation, Administration, and User’s Guide 21

Notifications, Alarms, and Data Buffering

The CS administrator can setup logging, notifications, and alarms to alert

administrators about problems. System generated messages on CS and the

connected servers or devices can be sent to syslog servers for handling. The

administrator can also configure data buffering to store data from

communication on serial ports for monitoring.

Data from communication with serial-connected consoles can be stored:

• Locally in the CS’s flash memory, or

• Remotely either on an NFS server or a syslog server.

Syslog Servers

Messages about the CS and connected servers or devices can be sent to a

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.

Prerequisites for Logging to Syslog Servers

Before configuring syslogging, the CS administrator must ensure that syslog

server is pre-configured with a public IP address, and it is accessible from CS.

The CS 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 CS.

Facility numbers are used on the syslog server for handling messages

generated by multiple devices.

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

locations. The available facility numbers are Local0 through Local7.
