Notifications, Alarms, and Data Buffering

For more background about setting up logging, notifications, alarms, and for 
links to all related procedures in this manual, see “Configuring Logging, 
Alarms, and SNMP Traps” on page 55.

Messages about the KVM/net, its connected PMs, and other connected 
devices can be sent to central logging servers, called syslog servers. Data from 
KVM-connected computers can optionally be stored in files on syslog servers. 

Syslog servers run operating systems that support system logging services, 
usually UNIX-based servers with the syslogd configured. 

An already-configured syslog server must have a public IP address that is   
accessible from the KVM/net. The KVM/net 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 KVM/net.

Facility numbers are used on the syslog server for handling messages 
generated by multiple devices. See “Facility Numbers for Syslog 
Messages” on page 54 for more background on how facility numbers are 
used.

Each syslog server has seven local facility numbers available for its system 
administrator to assign to different devices or groups of devices at different 
locations. The available facility numbers are: Local 0 through Local 7. 

The syslog system administrator sets up a server called “syslogger” to handle 
log messages from two KVM/net units. One KVM/net is located in São Paulo, 
Brazil, and the other KVM/net is in Fremont, California. The syslog server’s 
administrator wants to aggregate messages from the São Paulo KVM/net into 
the 

local1

 

facility, and to aggregate messages from Fremont KVM/net into 

the 

local2

 

facility.
