Querying a Protection Event¶
On the Events page, you can view events generated for blocked attacks and logged-only attacks. You can view details of events generated by WAF, including the occurrence time, attack source IP address, geographic location of the attack source IP address, malicious load, and hit rule for an event.
Note
If you have enabled enterprise projects, you can select your enterprise project from the Enterprise Project drop-down list and view protection event logs in the project.
Prerequisites¶
Constraints¶
On the WAF console, you can view the event data for all protected domain names over the last 30 days. You can authorize LTS to log WAF activities so that you can view attack and access logs and store all logs for a long time. For more details, see Using LTS to Log WAF Activities.
If you switch the WAF working mode for a website to Suspended, WAF only forwards all requests to the website without inspection. It does not log any attack events neither.
If the security software installed on your server blocks the event file from being downloaded, close the software and download the file again.
