I accidentally set a One-Time Maintenance Window for a server to 1 week, causing the status to remain PAUSED. How can I resume the sensor?
To resume the one-time-window, navigate to the object where it was set. Under Schedules, Dependencies and Maintenance Window | Maintenance Window, select Not set (monitor continuously).
