In my “new” position, the ConfigMgr environment that I administer is a demonstration environment where we show off our product to prospective customers. That means in the environment we have “real” machines that are VM’s and then we have additional devices that have been manually added to ConfigMgr with hardware inventory information, but they never check in with ConfigMgr because they are not physical devices. By default ConfigMgr has been cleaning out these devices every 90 days. Because I try to avoid repetitive work as much as possible, and because I don’t want to have to keep adding devices every 90 days, it’s time to see what I can do to change the length of time that inactive clients are in ConfigMgr before cleanup.
After a couple of quick searches, it looks like there is a setting that determines if inactive clients should be removed from the ConfigMgr database and another that determines how long Hardware Inventory is maintained. Here’s where to get to the settings:
- Step 1: Select Administration on the left hand side of the ConfigMgr console
- Step 2: Select Sites under the Site Configuration folder on the left hand side of the ConfigMgr console.
- Step 3: Select Site Maintenance at the top right of the ConfigMgr console.
The Site Maintenance window will open. Select Delete Aged Discovery Data. This setting determines how long Discovery Data is maintained in the ConfigMgr database. When this data is completely deleted for a device, the device is removed from the ConfigMgr database and console.
Because I also want to make sure that the Hardware Inventory is maintained for our inactive devices, I have also selected Delete Aged Inventory History.
The Delete Aged Inventory History Properties box will open, change the setting Delete data that has been inactive for (days): setting to your preferred setting.
This should keep the inactive devices in our ConfigMgr database, so we can use them for demo purposes, and keep the associated Hardware Inventory connected with them. More information about ConfigMgr maintenance tasks are located here. Microsoft reference for Maintenance Tasks.
