Querying Logs

A log records the operations and major events of the management system. By querying logs, you can learn about the running status and operation details of the management system.

Prerequisites

You have the operation rights for Log Management.

Context

Management system logs are classified into security logs, system logs, and operation logs.

Security logs record security operations that are performed on the management system, such as logging in to the server, changing passwords, creating users, and logging out of the server.
System logs record the events occurred on the management system, such as abnormal running, network failures, and attacks to the management system. These logs help you analyze the NMS status and rectify faults.
Operation logs record the user operations that are performed on the management system.

Procedure

Choose System > System Management > Log Management.
In the navigation tree in the left pane, choose Security Logs, System Logs or Operation Logs.
On the page, view the log information, or set search criteria to view specified log information.
After clicking the value in the Details column of the target log, you can view logs details.

A maximum of 1000 characters can be displayed in Details. The excess characters are displayed in the A-B form.

The management system server time is used for the filter criteria Time period. The value is 24 hours before the current time. For example, if the current time is 11:00:00, November 12, 2020, the default value of time period is from 11:00:00, November 11, 2020 to 11:00:00, November 12, 2020.
