We want to monitor alive systems daily at a scheduled time(after office hours). We have users who repeatedly fail to switch off their workstations after office hours, even after several requests to help save power, and manually checking and switching off is not possible, so we want to generate a history log of days when their systems were kept on, so that they understand the loss they are generating. We have NSClient++ installed in these workstations, but how will be schedule a one time checking? We already have hourly checks and alerts for rest of our critical servers. thanks ananth.
