how to check traffic logs in fortigate firewall cli

CLI Reference . 1: disk. A log message records the traffic passing through FortiGate to your network and the action FortiGate takes when it scans the traffic. If FortiGate logs are too large, you can turn off or scale back the logging for features that are not in use. The FortiAuthenticator has CLI commands that are accessed using SSH or Telnet, or through the CLI Console if a FortiAuthenticator is installed on a FortiHypervisor. option- Option. The Create New Log Forwarding pane opens. The data collected in this guide is needed when opening a TAC support case.When parts of this data are not present, the assigned TAC engineer will likely ask for it. This fix can be performed on the FortiGate GUI or on the CLI. Select All or Any of the Following Conditions in the Log messages that match field to control how the filters are applied to the logs. Enable/disable implicit firewall policy6 logging. Enter the IP address of the remote server. You should log as much information as possible when you first configure FortiOS. Enter a name for the remote server. In addition to logging where events occur within the network, the traffic log events must also identify sources of events, such as IP addresses, processes, and node or device names. Traffic logs record the traffic that is flowing through your FortiGate unit. The purpose of logs is to speed up your problem solving and save you time and effort. 09:08 AM 12-03-2020 The logs displayed on your FortiManager are dependent on the device type logging to it. Devices whose logs are being forwarded to another FortiAnalyzer device are added to the server as unregistered devices. It is difficult to troubleshoot logs without a baseline. Enable/disable adding resolved domain names to traffic logs if possible. Forward traffic logs concern any incoming or outgoing traffic that passes through the FortiGate, like users accessing resources in another network.Local traffic is traffic that originates or terminates on the FortiGate itself when it initiates connections to DNS servers, contacts FortiGuard, administrative access, VPNs, communication with authentication servers and similar.This traffic also generates log messages. Select the type of remote server to which you are forwarding logs: FortiAnalyzer, Syslog, or Common Event Format (CEF). This site was started in an effort to spread information while providing the option of quality consulting services at a much lower price than Fortinet Professional Services. Checking the logs A log message records the traffic passing through FortiGate to your network and the action FortiGate takes when it scans the traffic. 01-06-2022 If you need to, increase the level of logging (such as from Warning to Information) to obtain more information. If you are forwarding logs to a Syslog or CEF server, ensure this option is supported before turning it on. Also attach the configuration backup so TAC can check what was configured.Yes: What has changed since the time it was working?-Standalone Upgrade: review the release notes for known problems. 1. Technical Tip: Displaying logs via FortiGate's CLI Associating information about where the event occurred within the network provides a means of investigating an attack, recognizing resource utilization or capacity thresholds, or identifying an improperly configured network element. This ensures that you will be notified if the increase in logging causes problems. Scope, Define, and Maintain Regulatory Demands Online in Minutes. Enable/disable inserting policy name into traffic logs. The purpose of logs is to speed up your problem solving and save you time and effort.

Debug log may also be required.When opening a TAC support case, attach them and in more complex scenarios, the traffic path is needed as well:(ie: PC >> port1 (vlan 100, vdom TEST, policy 17) >> zone PROD >> vdom link TEST_to_PROD >> port9 (vlan 15, policy 413) >> internet port wa1 )Traffic logs (logging must be enabled in policy) or Security logs (AV/Webfilter/IPS/etc. Local traffic does not fall under the same policies as traffic passing through the FortiGate.
