[Observium] restarting snmp service on windows server flags the server as down in observium

Hi, I have an alert that says if the device_uptime is less than 360, alert that the server was down. I happened to restart the snmp service on several of my servers and was surprised to find the alert triggered. I am guessing that when snmp restarts, the uptime counter goes to zero? Is there any way to get a true read of the uptime? I am trying to alert if the server rebooted within the poling window.

thanks

Tony
