Default Level

3: Management level

Usage Guidelines

On the FW, service modules generate logs and control the log volumes. The information center processes the received logs.

When the number of logs that are generated within a specified period (T) exceeds the threshold, the service module, with the buffer mechanism, saves extra logs to the buffer and does not send them to the information center.

You can run the display buffer command to view the statistics about log information in the buffer, including:

Discarded logs
Sent logs
Log sending rate

Example

# View the statistics about logs cached in the buffer SNMP_SET on the service module SNMP.
