System Logging Process
By default, routers are configured to send syslog messages to a syslog process. The syslog process controls
the distribution of messages to the destination of syslog messages such as the logging buffer, terminal lines,
or a syslog server. The syslog process also sends messages to the console terminal by default.
Format of System Logging Messages
By default, the general format of syslog messages generated by the syslog process on the Cisco IOS XR
software is as follows:
node-id : timestamp : process-name [pid] : % message -group -severity -message -code : message-text
This is a sample syslog message:
RP/0/RSP0/CPU0:router:Nov 28 23:56:53.826 : config[65710]: %SYS-5-CONFIG_I : Configured
from console by console
