  • System Maintenance Start Time—Select the time to start system maintenance. The default is 2:00 AM. This activity is logged in the General Syslog.
  • Refresh Auto-Identified Device Interval—Select the refresh time, in days, that the appliance checks for new auto-identified log sources that you add.
  • Enable Daily AD User Cleanup Task—Select this check box and specify the time when the daily task of cleaning up Active Directory (AD) users must run. When an AD user account is used to login to LogLogic LMI, a corresponding user is created in LogLogic LMI. The task runs if this check box is selected and if the user credentials are specified under the Administration > System Settings > Remote Servers > Active Directory section, and deletes these corresponding LogLogic LMI users from the Management > Users tab in any of the following scenarios:
    • The AD user is disabled or deleted on the AD server
    • The AD user is removed from all associated roles or groups on the AD server
  • Optimize Device Selection List—Show all Source Devices is the default. If the appliance has more than 4,000 devices, selecting Show Only Device Groups improves display performance on many GUI pages. Show Only Device Groups limits device selection lists to device groups; individual devices do not appear in the device selection lists. This selection affects:
    • All LX or MX Real-Time and Summary report filter pages
    • Search Archived Data, Real-Time and Scheduled Search tabs
    • Devices tab for Alerts
    • Devices tab for Manage Users
    • Message Routing
    • Import/Export
  • Sort the Management Station Status by—Select the default sort order for displaying remote appliances (RAs) in the Management Station on the Dashboards > Management Station Status page. The default sort order is ID. Other options are:
    • Model
