To avoid unnecessary network traffic during non-agent based scanning, not all Windows computer data is rescanned all the time. As your computer's operating system does not change on a regular basis for instance, it makes sense not to rescan this data during every scan attempt. By default, operating system data is rescanned once every 3 days at most. Each item that's scanned runs on its own schedule, which is called an "item interval" within Lansweeper. Examples of other scan items are: BIOS, memory, software, processor and video card information. Though Lansweeper sets a default configuration for your item intervals, it is possible to customize these values to suit your needs.
To configure how often scan items are scanned, do the following:
- Browse to the following section of the web console: Scanning\Scanned Item Interval
- Place your cursor in the Refresh (X days) value of a particular scan item, make the desired change and hit Enter while your cursor is still present in the line to save the change.
- A value of 5 means that, when a computer is rescanned, the specified data will only be updated if it hasn't been updated in the last 5 days.- A value of 1 means that, when a computer is rescanned, the specified data will only be updated if it hasn't been updated in the last day.- A value of 0 means that, when a computer is rescanned, the specified data will always be updated.- Scan items marked in red are disabled and will never be scanned. You can tick the Enable checkbox to enable them.- Scan items marked in gray cannot be disabled. Disabling these items would lead to unexpected scanning behavior.
- The scanning targets and methods listed below respect item intervals. When Batch Scanning rescans a Windows computer for instance, it will (by default) only update OS information if that data hasn't been updated in the last 3 days.
- Active Directory Domain- Workgroup- IP Range- Asset Group- Asset Type- Report- Windows Computer- Active Directory Computer Path- Batch Scanning- LsClient, a scanning method that has been discontinued in favor of the more powerful and more secure LsPush
- The scanning targets and methods listed below DO NOT respect item intervals. When LsPush rescans a Windows computer for instance, it will always update all (enabled) scan items, regardless of what their schedules are. All computer data will be refreshed.
- Active Directory User/Group Path, as this only scans users and groups, not computers- Windows Computer (Eventlog only)- Active Directory Path (Eventlog only)- LsPush- Rescan buttons found on the left in asset overviews, reports and on webpages of individual computers
- When you browse to a Windows computer's Lansweeper webpage and open the Scan time tab, you can see when a specific scan item was last rescanned for that computer.
