with help of our dev team, I have update for you.
The resource "Overall Devices Backed Up vs. All Devices" gets its data from the Backup_vs_AllNodes NCM table. Are there any rows since April 14th?
This table is populated by ‘SolarWinds Orion NCM Caching Service’ automatically once per day. Please check if this service is running.
Thanks, Jiri. That was the fix. At some point since 4/14, the NCM Caching Service had stopped (maybe during the 7.0.2 upgrade).
'Might be a good feature request if Orion monitored its own health and alerted in the top bar (like where new blog posts and updates are advertised) when a service isn't running.
Glad to hear that it helped.
Taking your suggestion into account for future development.
