Troubleshooting Tip: System Event Summary is disabled

[ychia]

Description	This article describes how to fix an issue where the customer is unable to view the summary report under system events. The tab cannot be selected in the UI under Log & Report -> System Events -> Summary tab.
Scope	FortiGate 7.2.x.
Solution	To enable historical FortiView verify if disk storage is available, if the FortiGate device doesn't have disk the summary tab feature will not be available. If the device supports disk storage, verify if disk logging is enabled with the following command: show log disk settings  If the disk logging is not enabled, use the following commands to enable disk logging: config log disk setting     set status enable end To enable the option, it is necessary to enable Historical FortiView under GUI -> Log & Report -> Log Settings. Alternatively, enable Historical FortiView using the CLI command below: config report setting     set fortiview enable end The summary Tab is also available when the log data source is FortiGate Cloud. Note: After upgrading FortiGate from v7.2.x to v7.4.x, the summary tab is not available when the log data source is FortiAnalyzer. A tentative fix for this issue would be in FortiAnalyzer update v7.4.7 and v7.6.4.
