Log Message Format

The log messages for the switch have a standardized format. All system messages are tagged with the following information, except that alarm type and alarm status apply to alarm messages only:

The following messages are examples of an informational message for CLILOG:

The system encrypts AP information before writing it to the log file.

The encrypted information in a log file is for debugging purposes. Only a Customer Service engineer can decrypt the encrypted information in a log file. CLI commands display the logs without the encrypted information. Do not edit the log file.

The following table describes the system message severity levels.

Table 1. Severity levels

Severity level

Definition

EMERGENCY

A panic condition that occurs when the system becomes unusable. A severity level of emergency is usually a condition where multiple applications or servers are affected. You must correct a severity level of emergency immediately.

ALERT

Any condition requiring immediate attention and correction. You must correct a severity level of alert immediately, but this level usually indicates failure of a secondary system, such as an Internet Service Provider connection.

CRITICAL

Any critical conditions, such as a hard drive error.

ERROR

A nonfatal condition occurred. You can be required to take appropriate action. For example, the system generates an error message if it is unable to lock onto the semaphore required to initialize the IP addresses used to transfer the log file to a remote host.

WARNING

A nonfatal condition occurred. No immediate action is needed. An indication that an error can occur if action is not taken within a given amount of time.

NOTIFICATION

Significant event of a normal nature. An indication that unusual, but not error, conditions have occurred. No immediate action is required.

INFO

Information only. No action is required.

DEBUG

Message containing information useful for debugging.

FATAL

A fatal condition occurred. The system cannot recover without restarting. For example, a fatal message is generated after the configuration database is corrupted.

Based on the severity code in each message, the platform dispatches each message to one or more of the following destinations:

You can log system log messages to external system log hosts with both IPv4 and IPv6 addresses with no difference in functionality or configuration except in the following case. When you configure the system log table in EDM, under the System Log Table tab, you must select either IPv4 or IPv6.

Internally, the switch has four severity levels for log messages: INFO, WARNING, ERROR, and FATAL. The system log supports eight different severity levels:

The following table shows the default mapping of internal severity levels to syslog severity levels.
