You notice you are no longer receiving volume statistics from Windows servers; what is the most likely cause?

• A. Windows credentials stored in NPM are expired
• B. Volume statistics are temporarily disabled
• C. The Windows servers are rebooting
• D. The Orion service cache needs clearing

Answer: (A)

The main concept is that Windows volume data in NPM is collected by authenticating to each server with Windows credentials stored in SolarWinds NPM. When those credentials expire, the data collector can’t log in to the Windows servers to query disk performance counters, so volume statistics stop coming in. That’s why this option is the best answer: expired credentials directly block the data collection process. If the credentials were still valid, the collector would be able to connect and pull the volume data again. If volume statistics were simply disabled, you’d expect to see a deliberate setting or a clear status indicating the metric is turned off. If the servers were rebooting, there would typically be a reboot window with a temporary gap rather than a persistent lack of data. Clearing the Orion service cache would generally affect stale data or responsiveness, not specifically prevent fetching volume stats.
