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.
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 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).
