Uptime information seen in uptime calendars on computer webpages is indeed stored in tblUptime. You can clear tables using DELETE/TRUNCATE and execute scripts in the Lansweeper web console under Configuration/Scanning Setup/Database Scripts, but keep in mind that:
- We do not provide support for writing custom database scripts.
- Any scripts are run at your own risk. Create a database backup first.
- SQL Compact doesn't support the TRUNCATE command, but only the DELETE command.
Also note that you can perform automated uptime cleanups using the "Delete uptime data after XX days" option under Configuration/Scanning Setup/Server Options. Cleanups are performed when the Lansweeper Server service is started and subsequently every 24 hours.
