Additional Information
The event ID begins with a prefix that
indicates the generating software process.
Some processes on a Services Router do not
use codes. This field might be blank in a
message generated from such a process.
An Event can belong to one of the following
Type categories:
Error—Indicates an error or failure
condition that might require corrective
action.
Event—Indicates a condition or
occurrence that does not generally
require corrective action.
A severity level indicates how seriously the
triggering event affects routing platform
functions. When you configure a location for
logging a facility, you also specify a severity
level for the facility. Only messages from the
facility that are rated at that level or higher are
logged to the specified file.
