Hi WDRAIN1!
I see that you are using Patch Management Solution 8.5
1. If your managed client computers have "Software Update Agent" 8.0.x/8.1.x/8.5 version, then they will send pending reboot event nse file in "Inv_Software_Update_Distribution_Status" table
This stored procedure 'spPMCore_RebootStatusReport' shows report data of currently pending reboot for managed client computers with "Software Update Agent" plug-in 8.0.x/8.1.x/8.5
Example of data in "Inv_Software_Update_Distribution_Status" table where are records about pending reboot after patch updates installation on 8.0.x/8.1.x/8.5
'Pending Reboot' records in "Inv_Software_Update_Distribution_Status" table have DistributionStatus = 65536
2. 'Pending Reboot' events will be available in "Evt_Reboot" table only from managed client computers which have "Software Update Agent" plug-in version 7.x
This stored procedure "spPMCore_RebootStatusReport7_0" shows pending reboot records from 'Software Update Agent' 7.x
You can check both 'Restart Status" reports for 7.1.x as well as for 8.0.x, 8.1.x & 8.5 clients. Just clone reports via mouse right click menu and go to edit mode to check which stored procedure works for them and which tables/views are parsed.
Thanks,
