Configuring the information center

The information center on a device classifies and manages logs for all modules so that network
administrators can monitor network performance and troubleshoot network problems.

Overview

The information center receives logs generated by source modules and outputs logs to different
destinations according to user-defined output rules. You can classify, filter, and output logs based on
source modules. To view the supported source modules, use info-center source ?.

By default, the information center is enabled. It affects system performance to some degree while
processing large amounts of information. If the system resources are insufficient, disable the information
center to save resources.

Log types

Logs are classified into the following types:
• Common logs—Record common system information. Unless otherwise specified, the term "logs" in
this document refers to common logs.
Diagnostic logs—Record debug messages.
•
Security logs—Record security information, such as authentication and authorization information.
•
Hidden logs—Record log information not displayed on the terminal, such as input commands.
•
Trace logs—Record system tracing and debug messages, which can be viewed only after the devkit
•
package is installed.
• Custom logs—Record vendor-specific information.

Log levels

Logs are classified into eight severity levels from 0 through 7 in descending order. The information center
outputs logs with a severity level that is higher than or equal to the specified level. For example, if you
specify a severity level of 6 (informational), logs that have a severity level from 0 to 6 are output.
