Section 8. Configuring System Logs

This section provides information for managing system logs. System logs enable viewing device events in real

time and recording the events for later usage. System Logs record and manage events, and report errors and

informational messages.

This section includes the following topics:

• Defining Log Settings

• Viewing Temporary and Flash Logs

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.

The following table lists the available system log severity levels and the corresponding messages:

Table 3: System Log Severity Levels

Emergency 0 The highest warning level. If the

device is down or not functioning

properly, an emergency log message

location.

alert log is saved if there is a serious

device malfunction. For example, all

device features are down.
