Once I roll out the agent some computers show up right away with inventory, some after 12 hours are showing up as "Monitoring" with no problems, but are giving an error under "Deployments and Inventory" if I run the "Collect Inventory" manually it seems to then work ok. Why are these computers not collecting inventory on their own? Does it take longer than 12 hrs? Should I just wait? Also why are some working right away?Thanks
