Defining Log Settings
Event messages have a unique format, which is the Syslog protocols recommended message format for all error
reporting. For example, Syslog and local device reporting messages are assigned a severity code and include a
message mnemonic which identifies the source application generating the message. This allows messages to be
filtered based on their urgency or relevancy. The message severity determines the set of event logging devices
that are sent for each event message. The default severity for all logs is Informational, with the exception of logs in
the Remote Log Server, which are Error.
