When increasing logging levels, ensure that you configure email alerts and select both disk usage and log quota. option- Option. Turn on to configure filter on the logs that are forwarded. This step in troubleshooting can be forgotten, but its an important one. Click Log Settings. Fine tune the profiles/policy recently added/removed, so that it allows the traffic.No: Check why the traffic is blocked, per below, and note what is observed. Click Create New in the toolbar. Select the type of remote server to which you are forwarding logs: FortiAnalyzer, Syslog, or Common Event Format (CEF). Enable/disable brief format traffic logging. As with most troubleshooting steps, before you can determine if the logs indicate a problem, you need to know what logs result from normal operation. Aggregation mode can only be configured using the CLI. Name. - Check if the traffic flows ok when policy is changed to flow-based, instead of proxy-based.Traffic logs, packet captures, and debug flow are the tools TAC use further to check that, always in conjunction with the configuration file (backup from GUI of Global context). 07:15 AM For more information on Logging and Log Reports, see the Logging and Reporting handbook chapter. Logging and reporting can help you in determining what is happening on your network, as well as informing you of certain network activity, such as detection of a virus or IPsec VPN tunnel errors. For details on configuring logging see the Logging and Reporting Guide. A log message records the traffic passing through FortiGate to your network and the action FortiGate takes when it scans the traffic. Fortinet Fortigate CLI Commands - cmdref.net Logs also tell us which policy and type of policy blocked the traffic. This fix can be performed on the FortiGate GUI or on the CLI. option-resolve-port: Enable/disable adding resolved service names to traffic logs. 3: forticloud. option- Option. Set to On to enable log forwarding. Forwarding mode only requires configuration on the client side. This ensures that you will be notified if the increase in logging causes problems.

Enable implicit firewall policy logging. On FortiWeb you can view event logs. Technical Tip: Displaying logs via FortiGate's CLI. Enable/disable inserting policy name into traffic logs. Without establishing the source of the event, it is impossible to establish, correlate, and investigate the events leading up to an outage or attack. Enter a name for the remote server.

You should log as much information as possible when you first configure FortiOS. Compare current logs to a recorded baseline of normal operation. Edited on No configuration is required on the server side. 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.
