Hi Tony,
Some devices don’t give an accurate uptime figure. I think on windows we end up using the snmp agent time, because that’s the only time available.
Mike might have a more accurate explanation.
I’m not sure if we get a better uptime from WMI, though.

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
