Understanding the Importance of Checking Logs in Fortigate Firewall CLI

The Fortigate Firewall CLI (Command Line Interface) is a powerful tool for managing and configuring your Fortigate Firewall. One of the key aspects of managing your firewall is checking the logs. Logs provide valuable information about the activities and events that occur within your network and can help in troubleshooting, identifying security threats, and monitoring network traffic. In this article, we will explore the different methods to check logs in the Fortigate Firewall CLI.

1. Checking Logs in Fortigate Firewall CLI Using Command Syntax

The Fortigate Firewall CLI provides various command syntax options to check logs. One of the commonly used commands is the 'execute log display' command.

To overcome these limitations, you can use additional command options such as filters and log levels to narrow down the logs displayed.

To check logs using the 'execute log display' command, follow these steps:

Access the Fortigate Firewall CLI by connecting to the firewall using SSH, Telnet, or a console cable.
Enter the command 'execute log display'.
You can add optional parameters to filter the logs by using command options such as 'filter', 'level', 'start', and 'count'.
Press Enter to execute the command and display the logs.

Using the 'execute log display' command, you can quickly view the recent logs in the CLI. However, if you need to analyze a large number of logs or require more advanced filtering options, it is recommended to use the Fortigate Firewall web interface or FortiAnalyzer.
