Disk Space Control
Disk space of the FortiWAN Reports is being consumed by increasing report database. Once the disk space is used up, Reports will fail to continue log processing. Disk Space Control monitors the disk space status of Reports and triggers actions (purge and alert) according to user-defined conditions. Click Settings > Disk Space Control to enter the Disk Space Control settings page.
Purge old data from database
The Purge function is triggered by two conditions, day duration and percentage of free disk space. It will purge the old data from database when any of the two conditions is satisfied. This function purges data from database without data backup. Please refer section of Reports Database Utility in Advanced Functions for more information about database backup (See “Reports Database Tool”).
Days : Enter the number of days for the duration. When database data exceeds the day duration, Reports keeps the latest data of the day duration in database and purges the earlier data. Leave the field empty if you want disable the condition.
| Percentage (%) | : | Enter the percentage. When disk free space is less than the percentage of total disk space, Reports purges the earlier data from database to keep disk free space more than the amount. Leave the field empty if you want disable the condition. |
| Send notification after purge data | : | Click to enable notification via email after data purging. Settings > Email Server must be configured to ensure the notification (See “Reports Email Server”). |
Send Alerts
The alert function is triggered by two conditions, day duration and percentage of free disk space. It will alert administrator via email when any of the two conditions is satisfied. Settings > Email Server must be configured to ensure the notification (See “Reports Email Server”).
| Days | : | Enter the number of days for the duration. Reports sends an alert to users when database data exceeds the day duration. Leave the field empty if you want disable the condition. |
| Percentage (%) | : | Enter the percentage. Reports sends an alert to users when disk free space is less than the percentage of total disk space. Leave the field empty if you want disable the condition. |
Note that system schedules condition check for database purge and sending alerts at 04:00 A.M. everyday. You are suggested to set a looser condition for sending alerts than database purge so that you get the alert earlier before the data being purged, if you need to backup the data (via Reports database tool) in advance.
Mail To
e-mail address : Enter the email address for system delivers alerts and notifications to. Settings > Email Server must be configured to ensure the notification (See “Reports Email Server”).
