Information Hierarchy

Information Hierarchy

If too much information is generated, it would be impossible for a user to manually sort the information to differentiate between information about normal operations and information about faults. Fortunately, users can rely on information hierarchy, which classifies information according to severity. In this way, users can preferentially pay attention to information of higher severities.

Information has eight severities. The lower the numerical value of the severity level, the more severe the information. Table 3-2 lists severities.

Table 3-2 Description of information severities

Value

Severity

Description

0

Emergency

A fault causes the device to fail to run normally and requires a restart. For example, the device restarts because of a program exception or there is a fault about memory usage.

1

Alert

A fault needs to be rectified immediately. For example, memory usage of the system reaches the upper limit.

2

Critical

A fault needs to be analyzed and processed. For example, the memory usage falls below the lower threshold or BFD detects that a device is unreachable.

3

Error

An improper operation is performed or exceptions occur during service processing. The fault does not affect services but needs to be analyzed. For example, users enter incorrect commands or passwords or error protocol packets are received.

4

Warning

Some events or operations may affect device running or cause service processing faults and therefore require attention. For example, a routing process is disabled, BFD detects packet loss, or error protocol packets are detected.

5

Notification

A key operation is performed to keep the device running normally. For example, the shutdown command is run; a neighbor is discovered; protocol status changes.

6

Informational

A normal operation is performed. For example, a display command is run.

7

Debugging

A normal operation is performed, which requires no attention.

When information filtering based on severity levels is enabled, only the information whose severity level is less than or equal to the configured threshold is output. For example, if the severity level threshold is configured to 6, only information with a severity level ranging from 0 to 6 is output.
