Any feedback here? I would love a monitor that puts it into only up or unknown status, depending on if its powered on or not (ie, it tries to poll the IP to see if its alive, if not, it puts it into unknown state, instead of "down")
Status is been collected by ICMP Either SNMP so either if no response to the status packet it will be marked as Down what you required is the against the basic function for the monitoring system .
You can add as External Node it wont change the status where it wont collect the data however the Node will be listed that might help not sure
External Node: No Status
No data is collected for this node. Useful for monitoring a hosted application or other element on the node but not the node itself.
